Structural Analysis & Shape Optimization for a Control Arm of a Vehicle’s Suspension.

Abstract

This paper's primary goal is to develop and conduct a structural analysis of a sheet metal control arm used in the front suspension system. The control arm permits the wheel to move up and down but prohibits it from moving forward or backward. Additionally, the part is exposed to intense loads while performing its duty because the wheelbase is attached to the chassis on one end. To create sustainable and competitive products, component material and design selection is a crucial topic in the industry. Shape optimization can be utilized as a design tool in the initial stages of the design process to fully satisfy the strength and endurance requirements on a component level. Here the focus is on a control arm where the structural requirements on it involve the part being exposed to stress-strain due to the applied forces which can be treated and reduced during the optimization process. This would enable engineers to design better products while reducing the cost of development significantly.
