An Numerical Investigation of Open Coil Helical Compression Spring Using Different Alloys Materials for Light Duty Vehicle

Abstract

The main purposes of automobile open coil suspension systems are to isolate the chassis of the vehicle and the passenger from shocks and vibrations caused by irregularities of the road surface. The main objective of this work is to concentration on the stress and deflection of open coil helical spring used in light vehicle suspension spring with different materials. Finite Element Analysis of open coil helical spring has been carried out. In FEA 3D modeling is done in SOLIDWORKS and analysis is in ANSYS software. From the ANSYS results, it is observed that the maximum deflection in the Chrome Vanadium spring is 217.47 mm and in Chrome Silicon and Hard drawn steel springs are 212.83 mm and 212.36 mm respectively. From the ANSYS results, it also seen that the shear stress in the Chrome Vanadium spring is 757.21 MPa and in Chrome Silicon and Hard drawn steel springs are 753.65 MPa and 761.32 MPa respectively. From ANSYS results the maximum shear stress of Chrome Silicon alloy steel spring is less compared to Chrome Vanadium and Hard Drawn alloy steel spring.
