Finite Element Analysis of Open Coil Helical Springs

The present work attempts to analyze the safe load of the open coil helical spring. This work describes static analysis of the helical compression spring. In this research, steel helical spring related to light vehicle suspension system under the effect of a uniform loading has been studied by using SOLIDWORKS Software. This Software uses the displacement formulation of the finite element method to calculate component displacements, strains, and stresses under internal and external loads. Spring weight, maximum stress and deflection have been studied and factors of safety under the effect of applied loads have been calculated. The torque can be used to cause a rotation. The main objective of this research paper is to use of Finite element method (FEM) is a numerical technique for finding approximate solutions to boundary value problems for partial differential equations. It uses subdivision of a whole problem domain into simpler parts, called finite elements, and variation from the calculus of variations to solve the problem by minimizing an associated error function through some light on the fatigue stress analysis of springs used in automobiles. Reduction in weight is a need of automobile industry.
