Abstract: One of the important part of vehicle suspension is the shock absorber which is used to reduce shock impulse. Characteristics such as ride comfort and handling of a vehicle are mainly determined by the suspension system which transmits forces between vehicle and road. This paper deals with electromagnetic shock absorbers which is the future of suspension system. An electromagnetic shock absorber uses magnetic energy which can be actively controlled according to our requirement. In this case Magnetorheological fluid is used for controlled damping. Magnetorheological fluid is composed of nano magnetic particles which are suspended in a carrier fluid like oil. Magnetorheological fluid has the ability to change its viscosity according to the surrounding magnetic field. Like the traditional suspension systems, electromagnetic shock absorber also has no mechanical valves or small moving parts that can wear out.
Keywords: Electromagnetic shock absorber, suspension system, active control, Magnetorheological fluid.
