Vehicle Suspension Is The Mechanism Engineering Essay

Vehicle Suspension Is The Mechanism Engineering Essay This suspension system will fulfil their task by allow the forces to be distributed when the wheels are rotating on the ground, complying with design specification in every load state. Also we have the geometric variation of the body position from the trim which is caused by the static and quasi static forces, these three coordinates of the centre of gravity and three angles of the body reference system which is yaw, pitch and angle. These three angles are included under the vehicle static. The main work of suspension is to absorb the shocks and irregularities that are transferred to the body, this is accomplished by the damping systems. Normally it is possible that the tyre alone can isolate the shocks that are coming from the road, but this can only be accomplished when the vehicle is driven at a smooth road and at very low speed. Because tyres damping properties are not good enough to handle the road shocks, that is why we have suspension system, this allows the wheels to rotate freely, very safe and comfortable for driving. The basic different types of suspension systems are available today. These are semi Independent, dependant and independent suspension (Genta Morello, 2009, p. 153). Front Wheel Drive Diagram According to May, 2005, p. 470 state that, when we speak about suspension we have to include the terms sprung and unsprung weight. Sprung mass indicates as the weight of the vehicle that is supported by the springs including the frame, body and everything attached to them including the parts of the suspension and unsprung mass refers as the weight of the suspension components such as the wheels, tyres and brakes on which the springs rest, or all the parts of the suspension that are not supported by the springs The independent suspension As the name suggest the wheels in this system are attached independently, and this helps to reduce the impact that is transferred to the other wheel when the vehicle travels through road irregularities. This system involves McPherson strut, double wishbone and multilink. The strut contains shock absorber and spring is located by a ball joint, which is built in to the end of the suspension arm while the rubber mounting is moulded at the other end. This is one of the few reasons that make the suspension parts of this system work freely and it makes this by far the most common type of suspension in the market today. (3D auto.com, 2006). The negative part is it is required more solid chassis or sub frame structure, the slight change in wheel track causes the tyre to scrub during the bouncing of one wheel and the alignment of the steering geometry is critical and needs more attention (Crankshaft). http://www.autolign.co.nz/images/NolathaneIndRear2.gif Independent suspension system Dependent suspension This system usually connects the two wheels that are paralleled to each other on the same rigid straight and perpendicular axle, because all mechanical linkage work together, this can affect the movement of the other wheel when the vehicle road shocks or irregularities occur. Due to its ruggedness, this system is mostly often used on heavy truck, SUVs and rear wheel drive cars (Blue Ribbon Motoring LLC, 2010). http://img.alibaba.com/photo/51011605/Front_Dependent_Air_Suspension.jpg Dependent suspension system Semi independent suspensions: This systems utilizes a cross member that joins the two trailing arms. Regardless of the solid connection with the cross member and the trailing arms, the cross member will always twist with each up and down movement of the wheels. This twisting activity will give semi independent movement as well as stabilizer effect. The purpose of this suspension is to limit the body displacement to a minimum. This helps to increase the vehicle stability. Suspensions system can also be classified as passive or active. Passive suspension system involves shock absorber and spring. These two elements are passive because they cannot add energy to this type of suspension system and passive suspension is the one that receives the energy from sources like engine which affects the body motion. This limits the motion close to its static equilibrium (Genta Morello, 2009, p.358). The following diagrams are examples of passive and active suspension: Passive suspension system Active suspension system http://www.waset.org/journals/waset/v25/v25-11.pdf(pictures) SUSPENSION COMPONENTS: Coil springs: These are basically heavy wound steel wire used to support the weight of the vehicle as well as to absorb energy from road shocks or vibration between the road and the vehicle body. Springs usually located between control arms and chassis or around McPherson strut. They can be conical or spiral wound, constant rate or uneven rate, changeable pitch spacing and variable wire thickness. Coil springs can be customised and also be used in different variations and arrangement in the suspension system (Ciulla, 2002). Damping members When the vehicle travels through road shocks, the energy is given to the spring that is deflected, the spring creates an oscillating motion that results affects the handling and comfortability of the car. To stop this, damping members (shock absorbers) are installed. They are designed to store this oscillation energy and let the spring to return to its natural state. Few different types of shock absorbers are available today. These are hydraulic, lever type and telescopic direct acting type (Hillier, 1991, p. 364) http://static.howstuffworks.com/gif/car-suspension-8.gif Leaf spring: This type of spring is mainly used in the heavy and commercial vehicles. It is made up of one or more flat leaves or bent toughened steel or plates of composite material that are attached at the ends to the vehicle under body. It connects the vehicle frame to the axle by using the U bolt that secures the metal plates that rest against the leaf springs. The U bolt also keeps the spring level against the axle, this helps to stop the vehicle from shaking under the load when driving. It has a hook end that makes it flexible when the road shocks and vibration occur. The leaf spring shape allows them to flex and absorb bumps. This type of spring is very reliable and strong in carrying heavy loads, they also help in spreading the load on all over the chassis while the coil spring just transmit it to a single point (Spring-makers-resource.net). Torsion bar: These are usually metal bars which act as a spring and can also be moved about its axis through twisting. The main job is to resist the torque placed on the vehicle by twist it along its axis. This torque is created by the force when the vehicle is moving, once the torque has been counteracted, it normally returns to its natural state. This provides the resistance level to the forces that are generated by the movement of the vehicle. The major disadvantage of the torsion bar is it cannot provide the progressive spring rate while the progressive torsion bars have a tendency to crack when the diameter of the bar changes (CDX Online eTextbook). Anti roll bar/Sway bar/Stabiliser: This is fitted underneath the front and rear of the vehicle, connected at the lower control arm. They operate together with shock absorbers/struts to provide the vehicle with at most stability as well as body roll and improve cornering traction. When the wheels move at different angles from the other, an anti sway bar helps it in maintaining the balance and stability in case of a bad movement or a sway of the vehicle. It can also help in reducing over steer or under steer when the correct anti roll bars are chosen. They are fitted tightly and tend to give a bumpy ride as it transfers force direct to the other wheel. The tighter it is the safer the vehicle is from rolling (Turnfast.com, 2008). http://www.jamesglass.org/JGA/2labor/Z_laborIMAGES/00general/0-5_glossary/antiroll_bar.jpg Air spring: The air spring is designed to provide a vibration free and a smooth ride with a preset constant frame height. It also helps to reduce the spring oscillation so that the steering control is not compromised. It can work as a mechanical leaf type spring or used with them. The air spring system helps to reduce the road shock transfer to the chassis, cargo and the driver. In addition to that it can be easily adjusted according to the load and road conditions by using a height control valve. Other major components used in this system are pressure regulator, air lines and air springs. Zero stability to dampen suspension oscillation is the main disadvantage of this system and shock absorber is used to overcome this (Bennet, 2007, p. 268). http://www.streetrodparts.tv/400-ap-35-48-Ford-Mustang.gif Bushes: These are the linkage between the vehicle, springs, struts and shock absorbers. They tend to provide the movement point of the vehicle as well as avoiding metal to metal contact between the body and the suspension links. They are designed to be soft enough to maintain the alignments settings that help in maintaining steering control and allow the adequate rotational movement. Bushes are usually fitted where ever there is a metal to metal contact. However, the main disadvantage is, it is wearing out after some time and thus need to be replaced and it can be expensive and hard job depends on the types of bushes or where they are going to be fitted (Autolign). Common locations of vehicle bushes. http://www.autolign.co.nz/images/Bushes_000.jpg Ball joints: The main job for the ball joint is to enable the suspension to move on any angle or rotating the coupling that is usually the interface between knuckle and a control arm in a vehicle suspension. It performs as the pivot point between the suspension and the tyre and this helps in improving the performance (TRW Automotive, 2010). ball joints Control arms: This is normally connects the body chassis to the suspension of the vehicle. COMMON SUSPENSION SYSTEM TYPES: Trailing arm: This normally connected at the front of the chassis, it allows the rear to move up and down. Two of these become double trailing systems arm and usually work precisely the same as the double wishbone. The arms of this system can be seen from the side of the chassis, travel back equivalent to it. However it takes a lot of room underneath but it doesnà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢t experience the side to side scrubbing setback as the double wishbone systems (Longhurst, 2010). Trailing arm car suspension McPherson struts: This type of suspension is the further development of double wishbone, the higher transverse link is replaced by a pivot point on the wheel house panel, that takes the end of the piston road and the coil spring, this create the forces from all directions to be concentrated at this point and this causes a bending stress in the piston road. When this happens, a normal rod diameter in shock absorber must be increased by at least 18mm from 11 mm, this will avoid the detrimental elastic camber and camber exchanges. The parts of this system are usually combined into one assembly while its negative point is it takes a lot of room underneath the car (Reimpell, Stoll Betzler, 2001, p. 10). MacPherson Strut Double wishbone: This is an independently system, usually the wheel is directed by a pair of triangulated wishbones and track road. The lower wishbone is connected to the strut and this offers the vertical support. The sporty set up design of this system is due to its generous through loading width and a low height. This has a beneficial effect on for motion drive, the transmission of high active forces and road-holding. It also provides camber control that gives a better handling. The negative point is it can engage a space and expensive to design (Volkswagen Canada, 2010) http://www.autolign.co.nz/images/Bushtype1.jpg Multilink suspension: This is originated from the double wishbone, the suspension links use more than three lateral arms and more than one longitudinal arms, and these can be in various length and the angle can be away from their natural directions. The arms are normally connected by spherical joint or bushing at each end and this stopping them from bending, it also allows them to work in tension and compression. The pivots in this suspension are designed to allow the spindle to turn for the steering and change the geometry of the suspension by provide torque in all suspension arms. Different car manufactures have different designs. The main positive aspect is this system lets the vehicle to flex more, better handling because of the multi links while the negative part is it is more expensive to design and manufacture due to its complexity (Raiciu, 2009) Multi Link Transverse leaf spring: This system was used during the old days, it involves leaf spring and independent double wishbone together. The leaf spring is connected at each end of the lower wishbone and is mounted across the vehicle. A sub frame in the middle of the car is connected by the centre of the spring and each of the shock absorbers is mounted at each side of the lower wishbones (Longhurst, 2010) Transverse leaf spring suspension Solid-axle: leaf spring This provides an easy way of placing and mounting the hub and wheel units. Along with coil or leaf springs can create an effective non independent suspension system. The drive is transferred through the final drive unit and axles to the wheels, and this situation causes the axle to become a live axle. The torque reaction which is caused by a vehicle when it accelerates, causing a housing of the axle to spin in the opposite of the wheel rotation. During braking, a similar result can occur but with the twisting result in the way of wheel rotation. This can cause the twisting of the leaf spring and this can result in obstructing with the suspension motion ((CDX Online eTextbook). Transverse leaf spring suspension Solid-axle: coil spring This system has replaced leaf springs because they are lighter and have less unsprung weight that provides a comfortable ride but they cannot hold the axle in line. It is mainly used in the rear wheel drive vehicles. It is normally comes with one or more control arms and two lower control arms that manage the side movement and axle motion. The track bar may be needed when one upper arm is used, this connects the vehicle from one end to the other end. In reducing the vibration, rubber bushing can be used as the suspension travels through road irregularities. The track bar is not required when two upper arms are used (Monroe technology driven safety, 2008) The rear coil spring suspension is a variation of the rear leaf spring suspension often found in rear- Solid axle coil spring suspension diagram Beam axle: In this suspension the pair of front two wheels are connected to each other using a solid axle. This results in no camber loss from body roll because the wheels are always perpendicular to the road. It is also very simple structure since it doesnà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢t contain many parts, it is very strong and can be very useful in carrying bigger loads. The disadvantages of this suspension is, it is too big thus gives a lot of mass and takes a lot of space, since it is a dependent suspension the force from one wheel can be transmitted to the other wheel and this can result in an uncomfortable ride and reducing the vehicle stability in cornering (Lowry, 2004) http://www.automotivearticles.com/uploads/beam_axle_img_001.jpg Hydropneumatic suspension: This was originally invented by Citroen. The system compresses a gas rather than a fluid. The hydraulic fluid normally provide levelling and damping while the gas becomes a spring. Sometime this system can be driven using an engine driven pump that causes the hydraulic system to be pressurised and this assists it in levelling on the different height, jack assisting and stop the body roll. Fully powered braking system and power steering can also be available. The rear and front unit contains hydrolastic displacers, a small bore pipe is used to interconnect these displacers, and each displacer incorporates a rubber spring. The pipes, rubber, and fluid that are featured in this system always act as a damping system. The rubber springs are to keep the car level and freed from any tendency pitch. It can perform this without hinder the complete range of activity on any suspension and this provides the soft ride. The negative points are, it can be expensive to fix or replace it and sometime it does require a very well trained person to deal with (Marsh, 2001). Dynamic suspension This type of suspension is commonly used in Audi A4. It contains aluminium materials that are used to reduce an unsprung weight to the minimum. The differential in this system is moved to the front and the clutch to the rear, and the front axle has been repositioned 154 mm farther forward. Optimisation of axle-load distribution is achieved by relocating the car battery in the boot. By having additional differential at the rear, weight distribution is even better balanced. These vehicles will be more responsive and will take less effort to guide and position, resulting in better handling and very low under steer and gives good traction when cornering http://www.audiworld.com/news/07/b8-a4-in-depth/suspension/A4070151_medium.jpg (Audi AG, 2007) ELECTRONIC AND ACTIVE SUSPENSIONS This type of suspension is operated by the computer, which collects the data from different sensors such as how fast the vehicle is turning, speed of the wheels rotation, pitch, roll and height information. A simple system only involves maintaining the height level of the vehicle whereas, the four wheel height adjustment system can improves ground clearance when off road and minimises aerodynamic drag and economical fuel consumption. Suspension systems that are electronically controlled tend to be more expensive and are usually found in high performance and luxury cars. Active suspension systems are the most recent developments that involve microprocessing. This varies the orifice size of the restrictor valve in a hydraulic suspension or shock absorber which causes the effective spring rate to change, lateral force, load, acceleration, or a driver preference vehicle speed can be control inputs for the processor ( http://automobiles.mapsofindia.com/useful-information/modern-suspension-system.html FUTURE SUSPENSION: Active Electromagnetic Electromagnetic suspension that combines a passive spring with a brushless tubular permanent magnet actuator. During cornering and braking this system gives more safety and stability by presenting a pitch and an active roll. It can also eliminate the road shocks by due to the measurements, static and dynamic specifications of the actuator are developed. The fulfilling of the thermal and volume specifications can be completed by using a slot less external-magnet tubular actuator (http://alexandria.tue.nl/openaccess/Metis230153.pdf) (Koji, Masaharu, Takaaaki, 2006) INTEGRATED KINETIC TM H2 CES SYSTEM: This system is an interconnected passive reactive system that controls damping and reducing high roll and articulation stiffness. The tyre load optimisation improves performance. This is achieved by replacing four double-acting hydraulic cylinders each with two integrated CES damper valves on antiroll bars and shock absorbers. An automatic pressure maintenance unit (APMU), and a pair of accumulators with valves and interconnected hydraulic lines. The flow is restricted by the two CES valves in each corner, this allows the better performance and good handling. In addition to that, the CES damper valves are electronically controlled by the intelligent control algorithms in order to allow the wheel motions and a body control (Tenneco).

The Great Gatsby :: essays research papers

An essay on 'The Anatomy of Human Destructiveness by Erich Fromm. Amount of pages: 478. The book goes on in explaining the ways of aggression and how it reaches into man. Citing aggressive examples in the behavior of necrophilics and Hitler. The author goes into the early life of Hitler and his parents. How it had effect on what he became and his destructive way of life. He was a man that laid half way between reality and his fantasy. He had played war games up until the age of sixteen and after that he commanded his army like they had been a game. Taking risks with soldiers as well as ignoring precise information that would have been critical to his plans; and also the ignorance of British and US tolerance. He was a psychotic man who is a very good example of how far a man with destructive purpose can rise. Trying to explain aggressive behavior, there is focus on a core issue, instincts. Going through animal behavior and comparing it with human behavior and how similar our instincts are. There is also focus on examining primitive tribes. The object of these findings were to find out how warlike the tribes are. In the hunting-gatherers tribes, war is not as popular and profitable as in modern society. Two reasons for this is that these tribes don't have most valuable items and there is no shared type of currency to take. In these tribes, war was infrequent and not lead by permanent leaders. As opposed by modern days. What also differs is the conquest to kill as many of the enemy as possible. Aggression is ruled into several categories, such as Benign aggression which is one of a defensive type and malignant aggression which actually roots into other conditions. Premises, necrophilia, cruelty and destruction. The joy of destruction and abuse of it.   Ã‚  Ã‚  Ã‚  Ã‚  Destructiveness rest not only in acts but as worships. There is a case of idolatry, a man totally devoted to the monster of destruction. Kern, von salomon. A man like this and his acts are by no means normal, and supposedly caused by the world he knows, all morally, socially, honor, obedience is lost. The aggression takes control for many reasons. Although an extreme case of aggression, we see what may be societies cause on it's own people. Such a thing is a window to this picture.   Ã‚  Ã‚  Ã‚  Ã‚  Another focus would be on Milgram's electric experiment.

Augusta and Ncwo Essay

This report analyses the case study about â€Å"Augusta National Golf Club and NCWO battle for admitting female membership†. Mainly, this report will examine and identify the communication traits and flaws that can be found in this case study and will provide solutions and what should be done rather than taking a stand on who is right and wrong. Therefore, all the communications between Augusta’s Chairman, Mr. Johnson, NCWO’s Chairwoman, Ms. Burk, the CEOs of Sponsor companies, the Augusta members and the media were researched and studied. Furthermore, this report mainly uses secondary data such as newspaper articles and journals to support the arguments and ideas. Moreover, the core purposes of this report is to evaluate the interactions and point out some communication management factors and flaws from this dispute, set it as an example and provide solutions to be improved in the future business communication. Main body Augusta, the private golf club Augusta is the private golf club which its culture and membership are mainly reflected on its prestige and exclusiveness. Moreover, members of Augusta join the club to satisfy mutual interests and to fulfil the social needs and the need for self-esteem such as being a part of the highly regarded golf club in the country. Because it is a private club, it holds its legal rights to choose its own members. (Peraino, 2002). Furthermore, the club clearly specified the club (team) norms (obligation, preference and prohibition) such as â€Å"members are required to sign an agreement not to speak about the club† and have to withhold the membership information to the outsiders. Saporito). Therefore, Augusta organizational control can be identified as a bureaucratic control system where the Chairman, Mr. Johnson has the ultimate power to dominate the club’s affairs. NCWO On the other hand, the NCWO’s sole purpose is to promote women rights and members join the committee to achieve security and satisfy their mutual interests. As you can see from the case, Ms. Burk, the chair of NCWO usually do the decision making for the committee. Although the decision making criteria are not formally discussed in the case or in the media (newspaper articles), we can assume that NCWO lacks the rational decision making process in groups such as orientation, discussion, decision making and implementation. Also, in his article Munching (2002) states that â€Å"she (Burk) forgot to ask herself one question: What women want to do? † which clarify the lack of communication between members of the group and its chair. The dispute The offensive approach and the vulgar feedback It can be seen in the case that without deeply analysing the situation, Ms. Burk took an offensive approach demanding and insisting on female membership, base mainly on the speech about â€Å"inclusion of women in Augusta† by Mr. Lloyd Ward. Moreover, Augusta’s Chair, Mr. Johnson also gave a vulgar feedback to this demand which sparks into a dispute of gender issue. Moreover, negative impressions between them were formed on limited information and stereotyping where Burk is seems as the trouble maker and Johnson as the rigid discriminator. Therefore, this miscommunication and poor transaction of messages led to unnecessary conflicts and egotism of the two corresponding Chairs. The Sponsors, members and Burk When the direct demand fails, Burk took the indirect persuasion and argumentation approach through the Augusta’s sponsors for its prime event, the Masters. She appealed to CEOs of sponsor companies like Citigroup, IBM, Coca-cola, Cadillac and CBS using generalisation and cause-effect relationship methods of arguments to boycott the Masters. For example, she praised their stance in gender discrimination within their firm and point out the possible public opinion in the involvement with the Masters. However, only Citigroup and Coca-cola agreed to help her and these decisions can be seen as corporate social responsibility to raise their public images. On the other hand, others remain neutral to avoid uncertainties involving in the dispute. Moreover, she turns to persuade the members of Augusta, who are highly regarded CEOs of the corporate world. However, with them she used the illegitimate methods of arguments such as appeal to the masses and â€Å"ad hominem† whereby she threatens them and their organization by claiming to reveal the membership list and the â€Å"daily anecdotes of gender discriminations in their (members’) companies†. (2005). For instance, it is noted in Peraino’s (2002) article that â€Å"she told Newsweek that â€Å"We’ve already done quite a bit on the public-embarrassment front†Ã¢â‚¬ . In addition, she even tried to convince Tiger Wood not to participate in the Masters but he too was â€Å"criticized for suggesting that Augusta has a right to its exclusionary policies† (Gutner, 2002). Therefore, one can clearly see from the case study that Burk used many deductive logics and generalisations in influencing and communicating with the sponsors, the members and the players. Burk and Johnson From the start, Mr. Johnson strongly showed his assertiveness as well as his aggressiveness for his club and its membership rules. However, one can recognize the cognitive dissonances from Mr. Johnson’s feedbacks and replies where he imposed denials and unwillingness to change the traditional rules and culture. Moreover, this effect can also be found in Saporito’s article, as â€Å"he booted the Masters’ sponsors–Citigroup, Coca-Cola and IBM–so the companies wouldn’t face criticism by association† and adopted the commercial free move. In addition, Johnson and Burk took hold of some perceptual biases against each other and some of these are selective perception where both of them ignored each other’s rational reasons. Furthermore, stereotyping can clearly be seen between them where they posed each other as threats and arch enemies. Conclusion and results In conclusion, one can identify more communication flaws than the benefits in his case. This is mainly because the poor usage of appropriate communication features and the channels used to communicate, for example, Burk main communication channel with her advocates and opponents is through letters. Moreover, narcissism and egotism also got involved later in the dispute where both of the Chairs started to address and confront each other comments and feedback harshly rather than solving the dispute. (Munching, 2002). As a result, Johnson acquired victory by reasoning through generalization and analogy among private clubs and sororities claiming its legal rights to choose its own members. The dispute between Mr. Johnson (Augusta Golf Club) and Ms. Burk (NCWO) is very phenomenal in indicating miscommunications between two unfriendly organizations. As for the recommendations for this case, since the start, both parties should use more subtle and civil approaches to address the problem to each other and discuss in person how to compromise the situation. For example, Shiflett (2003) implies in his article that Augusta never meant to discriminate and it is only following its highly constructed social role as an all male-club. Moreover, they should utilize more â€Å"lateral thinking†, avoid what is right and wrong and conclude to the best possible solution. In addition, Burk should change her persuasion techniques towards more â€Å"features-benefits mix† and should drop her deductive logic on women rights and organizations. Furthermore, both of them should leave out their egotisms and stereotypical perceptions when dealing with the gender issue. On the other hand, while confronting with the members she should shows cause-effect relationships of their inaction and argues upon their specific reasoning. Munching, 2002). As for Mr. Johnson reactions, he should be more aware on the public images of the club and its members. Moreover, Augusta’s individual orientation of culture should swap with a more collective one where all stakeholders can give out their opinions. Last but not least, the channels used for communication in this case should be changed into more personal and face to face l ike personal meetings or through telephone. This was even suggested by Tiger Wood that â€Å"they’d sit down together and all would be resolved†. (Munching, 2002).

Vaccinations Should Be Mandatory Out Of Vaccinating Children

When it comes to certain topics there is always going to be controversy surrounding them; this is the case with the topic of whether or not children should be vaccinated. According to the Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) they recommend that children get vaccinated against up to 14 diseases within their first two years of life, and receiving booster shots as they get older. This idea leads to numerous debates on why children should be vaccinated or why parents should be able to opt out of vaccinating their children due to developmental concerns or religious beliefs. In my opinion, however, regardless of religious beliefs, vaccinations should be mandatory—unless there is a medical reason not to—because not only do vaccinations protect children from various diseases and can save their lives, but they also protect others around them and future generations. In April, California’s State Legislature moved forward a bill that would make it mandatory for children enrolled in public schools to be vaccinated, regardless of religious or personal beliefs. If the parents still do not want to vaccinate their children than they must homeschool them. In return, this sparked a huge debate on whether or not the bill should be passed.
