Investigations on Magnetic Suspension System of Shock Absorber by Finite Element Method

Abstract: The suspension system of two wheelers is depending upon spring type, hydraulic or pneumatic type of suspension systems. This present work gives deals with the magnetic suspension system and the magnetic suspension system is turning out to be the new option to the conventional suspension systems. The aim of this work is to study and investigate the response of two-wheeler suspension system, when it is subjected to road surface irregularities. This research work presents design, construction and working of magnetic suspension system. This system uses magnets and spring as passive dampers, which are used to reduce displacement and acceleration of spring mass in order to improve ride comfort. This type of Suspension has no problem of leakage of oil like hydraulic shock absorber. FEA analysis is carried out over the suspension spring with different materials such as Crome silicon, Carbon steel, NiCr, magnesium and Aluminium. With and without magnetic suspension is analysed for the stress and deformations. It is observed that the carbon steel has minimum deflection and the maximum stress induced in aluminium material.
