Abstract:

Now a day’s comfort and control are two major aspects in field of design and manufacturing. At present condition spring and damper system are used as shock absorber in automobiles. As concerned to comport and control their system are lagging to provide optimum level of performance. With view of increase the comfort and control electromagnetic suspension system introduced to fulfill the requirement of modern days. This seminar intended to explain the resurgence of interest in the suspension system in recent year and outline the significant challenges that lie a head in commercializing suspension system.

Introduction:

Bose, mention that word and music comes to mind specifically, audio systems for upscale cars, as well as expensive but worth-the-cost systems for the home. Business travelers might even connect that name with noise-canceling headphones that reduce some of the stress of flying. What one doesn't associate with Bose is automobile suspension. By and large, today’s vehicle suspensions use hydraulic dampers (shock absorbers) and springs that are charged with the tasks of absorbing bumps, minimizing the car's body motions while accelerating, braking and turning and keeping the tires in contact with the road surface. Typically, these goals are somewhat at odds with each other. Luxury cars are great at swallowing bumps and providing a plush ride, but handling usually suffers as the car is prone to pitch and dive under acceleration and braking, as well as body lean under cornering .On the other end of the spectrum, stiffly sprung sports cars exhibit minimal body motion as the car is driven aggressively, as cornering is flat, but the ride quality generally suffers. In an ongoing research project that has spanned over 24 years Bose has created a unique electromagnetic suspension system for automobiles that is close to commercial release and is set to replace traditional shocks and springs with electronic actuators. "This is the first time a suspension system is the same for a sports car and for a luxury car", said its creator, Dr Amar Bose, chairman and head of technical design. The result is a ride that is level and bump free over incredibly rough terrain and when the vehicle turns in to corners.

Suspension:
The main objectives of the suspension system are:

• To prevent the road shocks from being transmitted to the vehicle parts, thereby providing suitable riding and cushioning effect to the occupants. • To keep the vehicle stable while in motion by providing good road holding during driving cornering and braking. • Provides safe vehicle control and free of irritating vibrations and reduce wear and tear.

The different types of suspension system which are available are mentioned below.

1. Front Suspension:

Solid I-Beam:
It’s a Non-independent design .These is used on trucks and other large vehicles. Its economical and simple .It has low maintenance but poor handling.

Twin I-Beam:
Found on many Ford...
