Abstract
Now a day’s comfort and control are two major aspects in field of design and manufacturing, especially in the field of automobiles. Suspension is a major component of automobile. It decides the control of vehicle. At present condition spring and damper system are used as shock absorber in automobiles. As concerned to comfort 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.
Introduction
As mentioned above, the poor performance of conventional shock absorbing system lead the way to the application of electromagnetism to this field. The idea of application of electromagnetism was introduced by BOSE. It’s one of world famous brand for audio systems. So it was easy for them to deal with electro magnetism. 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.
Suspension
The main objectives of the suspension system
• 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.
• To keep body perfectly in proper level while traveling on uneven path
• To safe guard passengers and goods against road shocks
• To preserve the stability of the vehicle while in motion
• To maintain proper steering geometry
Challenges
Every automotive suspension has two goals. They are passenger comfort and vehicle control. Isolating the vehicle’s passengers from road disturbances like bumps or potholes provides comfort. Control is achieved by keeping the car body from rolling and pitching excessively, and maintaining good contact between the tire and the road.
Solution
In 1980, Bose founder and CEO Dr. Amar Bose conducted a mathematical study to determine the optimum possible performance of an automotive suspension, ignoring the limitations of any existing suspension hardware. The result of this 5-year study indicated that it was possible to achieve performance that was a large step above anything available. After evaluating conventional and variable spring/damper systems as well as hydraulic approaches, it was determined that none had the combination of speed, strength, and efficiency that is necessary to provide the desired results.
