THE DESIGN ENHANCEMENT AND ANALYSIS OF TWO WHEELER SUSPENSION COIL SPRING

A suspension system or shock absorber is a mechanical device designed to smooth out or damp shock impulse, and dissipate kinetic energy. The shock absorbers duty is to absorb or dissipate energy. In a vehicle, it reduces the effect of travelling over rough ground, leading to improved ride quality, and increase in comfort due to substantially reduced amplitude of disturbances. The design of spring in suspension system is very important. In this paper the design and analysis of a shock absorber coil spring is presented. 3D models are created using CATIA drafting package. The models are designed according to variation of the pitch of the spring and compared with the original dimensions of the spring. Static Structural analysis and Modal analysis are performed on the designed models of shock absorber by varying materials for the spring. The analysis is done by considering loads like bike weight, 1 person and 2 persons. The designed models and materials were compared to obtain best model and best material for coil spring in Shock absorber.
