Description
Summary:The Automotive suspension system is deployed to absorb the shock load vibrations due to undulations of the road surface. For vehicles like car, Helical coil springs along with dampers are used in the suspension system. It is expected to perform its function without affecting the stability, steering or handling of the vehicle. The suspension springs belong to the open coil type. The conical spring is a type which has an advantage in the fact that it has a compact structure and good stability, and it is used for bearing larger load and vibration attenuation. This paper aims to assess the performance of Stainless-steelconical springs if used in four-wheeler suspension system. The values of Spring Stiffness, Deflection, Critical Buckling Load and Relative Critical Deflection are calculated for the conical springs and compared with the helical springs. The CAD model of the springs was done using Solid Works and the Finite Element Analysis was done using ANSYS Workbench. The static analysis was performed. The Load and Boundary conditions were specified. The Total Deformation, Factor of Safety, Equivalent Stress, and Maximum Shear Stress of the springs were noted. The results obtained are compared with those of a conventional open coil spring and applicability of the constructed springs to the chosen vehicle is studied depending on the results obtained.
