Analysis and Optimization of FLCA Using Finite Element Based Topology Optimization Technique

Mechanical Engineering

Front lower control arm (FLCA) is a component used in a suspension system of a light vehicle. It plays a whittle role in handling the motion of the wheel during the bump, turning, and braking. The scope here in this present work is to optimize the front lower control arm with respect to weight with four different materials. Present work, the new design concept of FLCA is presented. CATIA software has been used for the modeling, design concept of the FLCA. After that, ANSYS software is used to analyze the structural strength and optimized the part using topology optimization technique to achieve accurate dimensions with less mass. To verify the initial work, existing model has been taken from literature as the base and verified it. The work also determines the natural frequency before and after optimization. The target of the new design is 20% reduction of the overall mass of the front FLCA which manufactured by suitable material. Finally, the work has been observed that using topology optimization technique reduce mass of the FLCA without owing its responses.
