ABSTRACT
Suspension bushing is an important link in shock absorber and it must be stiff enough to maintain alignment of suspension under loads. It is crucial for ride and handling characteristics and must be durable under highly variable loading. Such elastometeric bushings exhibit non-linear behaviour depending upon excitation frequency, amplitude and level of pre-load. Designing of Rubber bush is performed using suitable modelling software and FEA analysis is performed to predict behaviour of component against load applied. The different alternatives are suggested to get better model to satisfy endurance limit proposed by Gabriel India Ltd, Nashik. To satisfy testing criterion of Rubber Bush necessary design changes and relevant experimentation validation has carried out in GIL, Nashik Testing Lab.
