Coil spring type analysis using the finite element method

Abstract

Abstract Manoeuvre ability and driving comfort are the most important things in the automotive sector. Spring is a fundamental mechanical element that widely used in vehicle suspension applications. Holds loads perpendicular and absorbs shock loads from wheel vibrations so that they are not transmitted directly to the chassis. Therefore, the coil spring was made from a coil of high carbon steel rods in the form of a coil. The purpose of this article was to determine the differences in stress and strain strengths of several different types of coil springs. The types of springs used include the constant pitch spring, variable pitch spring, and barrel coil spring. Various types will be designed using Inventor software while the simulation used ANSYS 19.2 software. ANSYS engineering data used SUP 9 material and was subjected to a load of 6315 N. The results of the analysis showed that among the other three types, barrel coil spring has the lowest equivalent stress and maximum shear stress of 509.72 and 293.41 MPa, respectively, so it has the highest strength.
