Design and Experimental Analysis of Helical Suspension Spring with Different Materials

Automobile suspension plays an important role in passenger comfort and stability of the vehicle. So far now, many materials have been evaluated for manufacturing of helical suspension springs as per requirement. The objective of this work is a comparative study and analysis of suspension helical coil spring with two different materials (chrome silicon and hard drawn carbon steel) and perform experimental and static analysis using finite element analysis to determine the optimum material to reduce the stress and deflection. Suspension model is created in ProE CREO 2.0 and the model is structurally analyzed using ANSYS 15.0. Helical suspension springs of two materials are prepared and experimental tests are performed for analysis of physical characteristics for the two materials. The results and comparative study show the optimum material that can be selected as a spring material for efficient function and long life.
