Design and Analysis of an Automobile Helical Suspension Spring with Variable Cross-Section

The objective of this study is to conduct a comparative analysis of helical coil suspension springs made from chrome vanadium and hard-drawn carbon steel. The analysis includes both empirical and static strength evaluations using finite element analysis (FEA) to identify the optimal material for minimising the stress and deflection. The suspension model is created in Pro-E and structural analysis is performed using ANSYS. The physical properties of the two materials are compared through empirical analysis. The results of this comparative study help determine the most suitable material for suspension springs, ensuring improved performance and longevity.
