DESIGN AND ANALYSIS OF COIL SPRING IN VEHICLES USING FINITE ELEMENTS METHOD

Suspension system plays a very important role in new vehicles. Its duty is to damp, smooth out the shock impulse furthermore to absorb or dissipate energy so that the suspension system provides the comfort and safety for the passengers and vehicles. In this paper, the simulation of spring is carried out by using Solid works 2018 with specific dimensions and analysis it with finite element analyzer ANSYS 14. Three materials are selected to simulate the spring steel, copper alloy, and carbon composite. The deformation, strain, stress and shear stress are obtained numerically under various values of load (1500, 2000 and 2500) N. The results showed that the deformation in carbon composite is less than steel and copper alloy so that the carbon composite is the best material for helical spring and can withstand the load and deflection.
