Abstract : The main aim of this work has to develop the approximate analytical formulae for shock absorber used in suspension system which is designed to reduce shock impulse and dissipate kinetic energy. In a vehicle, it increases comfort by decreasing amplitude of disturbances and thus improves ride quality by absorbing and dissipating energy. When a vehicle is moving on a road and strikes a bump, spring comes into action quickly. After compression, spring will attempt to come to its equilibrium state which is on level road. Helical springs can be made lighter with more strength by reducing number of coils and increasing the area. Another compression spring is Wave Spring, overall length and operating heights of these springs are less than a normal helical spring due to which they reduce part weight and raw material cost for producing a spring. The results obtained by various mathematical modelling have been compared and an estimate of the error analysis has been carried out. This is comparatively little information of helical spring and wave spring. These techniques are used to determine parameters like fatigue life, deformation, stresses, safety factor in springs with different materials to adjust "Stiffness to weight ratio". Index terms - Compression spring, wave spring, helical spring, mathematical modelling, fatigue life, stiffness-weight ratio.
