Design and Analysis of a Lower Control Arm in Car by Finite Element Analysis Approach

Abstract

Abstract Suspension system is the most important part in any vehicle. It directly affects the human safety as well as performance. The lower control arm is a wishbone-shaped metal strut that attaches to the wheel assembly. Structural optimization techniques under static load conditions have been widely used in automobile industry for lightweight vehicle to increase its performance level. This study deals with finite element analysis of the lower control arm of MacPherson suspension system and its re-design under static loadings. The existing design of lower control arm from one of the light commercial vehicle is selected for the study. The finite element analysis is carried out to determine the deformation and stress distribution in the existing design. The main aim of this project is to redesign the lower control arm of MacPherson suspension system under the current boundary conditions and increase the safety factor from 1.3 to 2. The baseline model of the lower control arm is created by using solid modeling software, viz. CATIA. The present study is used to reduce the weight as well as cost of the lower control arm under permissible limits.
