A Finite Element Approach for Analysis of a Helical Coil Compression Spring Using CAE Tools

Abstract

Springs is defined as an elastic body that can reserve high level of potential energy, have various important role in industries. Helical spring is the most common element that has been used in car suspension system. Spring steel is low carbon alloy, medium carbon steel or high carbon steel with very high yield stress related to light vehicle suspension system. In this research paper AISI 9255, (containing 1.5%-1.8% silicon, 0.7%-1.0%manganese and 0.52%-.6% carbon) under the effect of a uniform loading has been studied. .The FE model of the helical spring has been generated in Pro-E Wildfire 5.0 software and imported in ANSYS-10 for finite element analysis, which are most popular CAE tools. Also finite element analysis has been compared with analytical solution for different loads under the same conditions to conclude.
