Abstract - This paper focuses on design optimization of an existing double wishbone type suspension system from a consumer vehicle. The suspension system acts as a key element in between the vehicle and the road, and has a significant impact on the handling and feel of the vehicle. The suspension system is a critical system that directly influences vehicle dynamics, ride comfort and overall driving experience.  Optimizing core suspension factors such as weight, strength and geometry are a key to achieving optimal performance, handling, ride quality and stability. Known for its precise handling characteristics and superior ride comfort, the double wishbone suspension is an ideal candidate for improving its design to a new ceiling. By using FEM with the principles of topology optimization, we aim to create an optimized control arm design that is lighter in weight as compared to its original design, without significantly affecting its strength characteristics.

Key Words:  control arms, double wishbone suspension, topology optimization, design, efficiency, lightweight design.
