Broadly speaking, suspension system consists of a spring and a damper. This system is aimed to improve vehicle performance on all terrain conditions from rough to flat surfaces. For example when the vehicle hits an uneven surface, the spring deforms from their original shape and return to their normal position but tend to over shoot and set up oscillations. This work emphasizes the method for designing and analyzing the suspension system for a race car in various aspects. Suspension systems must support both road handling and ride quality, which are at odds with each other. Suspension Systems: The purpose of the suspension system is to isolate the vehicle body from road bumps and vibrations while keeping the wheels in contact with the road. The design of front and rear suspension of a vehicle may be different. They are basically divided into two types of systems one is the independent system and other is the dependent suspension systems. For the rear wheel drive the vehicle has coil springs and trailing arms to position the axis longitudinally. The dvantage of this suspension system is that we can figure out the effect of moving each joint. This strut was designed by Earl S Mc Pherson. This report generally gives a review on various types of suspension systems, their layouts at the front and the rear, their role in handling, quality and durability of a vehicle during its operation .Also a brief introduction on role of the suspension systems in interaction with tyres and the dynamics of the complete vehicle is also explained. Wheel unit Location: When a vehicle is in operation, several forces operate to displace the wheel units- driving thrust, braking torque, cornering forces. Magnetic Suspension System,Ask Latest information,Abstract,Report,Presentation (pdf,doc,ppt),Magnetic Suspension System technology discussion,Magnetic Suspension System paper presentation details This reduces the dampening effect which causes the performance of the shock absorbers to deteriorate. This article provides a discussion on various solutions used in modern suspension systems of automotive vehicles. The load carrying characteristic depends on the diameter of the wire, its springs and spacing of the coils. A lower vehicle performs better on smooth roads but as the road condition vary the roads start getting transmitted causing discomfort. The rear suspension must maintain the alignment of the wheels with the front and even the frame. Its upper end is located in a moulded rubber mounting. Together with leaf spring it forms an effective, non independent suspension system. Ride handling is influenced by suspension system geometry. A coil spring is made of single length spiral wire which is heated and wound on the former to produce the required shape. In this research the ride and handling performance of a specific automobile with passive suspension system is compared to a proposed fuzzy logic semi Integral suspension system for motor vehicles based on passive components These springs can be used for many purposes and have many advantages like it can be moulded into any shape and is very silent during use. Its main advantage is that it can be used in the front as well in the rear of the vehicle. Preventing this oscillation is called dampening. So as to reduce these effects load adjustable type shock absorbers are used. 2.1. This drive shaft can be used as an upper link of the suspension. If there were no roads irregularities and roads were perfectly flat we would not have required the suspensions, but that’s not the case we have many road irregularities at present and so to make the ride better we need suspension systems that can make the ride handling, quality and durability of the vehicle more effective and also comfortable to the occupants in the vehicle. This is a standard hydraulic type, providing dampening action when heavy loads are placed on the rear of the vehicle. If the suspension reaches the limit of travel, these stops prevent the direct metal to metal contact helping the body of the vehicle and the suspension not to get damaged. Pressure on the oil is provided by the nitrogen gas at the base of the cylinder acting on a free-floating separation piston which separates the gas from the oil. It is also another type of non-independent type suspension system, as the deflection of a wheel on one side is transmitted to the other wheel also. The main problem is making the magnets strong enough when running off a cars electrical system. It suspends the body and associated parts so that they are insulated from road shocks and vibrations. During bumps, or compression, the rod and its piston move into the shock absorber. No plagiarism, guaranteed! We've received widespread press coverage since 2003, Your UKEssays purchase is secure and we're rated 4.4/5 on reviews.co.uk. The vehicle ride handling and quality can be improved by keeping the unsprung mass as low as possible, but the suspension systems should be strong enough to withstand the loads imposed on it during cornering, braking and uneven road surfaces. In the front wheel drive suspension, the control arm is a wishbone shape with two widely spaced mounting points. Passenger cars do not use this suspension system anymore but they are still being used in the heavy vehicles. Peer-review under responsibility of the organizing committee of ICOVP 2015. The shorter and thickness of the bar, stiffer is the spring rate. It uses two wishbone arms to locate the wheel consisting of two mounting points one on the chassis and one on the knuckle. They must be located longitudinally and laterally while still having the freedom to move vertically to allow suspension travel. Tyres have a vertical reaction point with the roadway for the fact that they manage all the input of forces and even the disturbances on the road because they perform on the action of the driver. As the piston moves in the cylinder, valves control the movement of the oil from one chamber to the other chamber. Abstract.

On vehicle with non independent suspension, leaf springs provide a simple means of performing these functions. This kind of suspensions system can maintain a constant height irrespective of load and automatically adjusts the damping and ride height of the vehicle and even enables the driver to influence the suspension characteristics. Principle of Suspension: The suspension system isolates the vehicle body from the road shocks and vibrations which otherwise would be transferred to the passengers and also to the load. suspension system TYPES OF SUSPENSION SYSTEM 1) INDEPENDENT SUSPENSION SYSTEM. The energy of road shock causes the spring to oscillate. We can also adjust the height of the shock absorber by changing the pressure, and also the stiffness of the suspension springs.
