Topology Optimization of the Actuating Arm

This paper explores the use of topology optimization (TO) to improve the actuating arm’s performance in drum brakes while minimizing material usage. The Fusion 360 software has been utilized to compare the outcomes of using three different materials: AlSi10Mg, AISI316L, and Ti6Al4V. The TO process optimizes the component’s shape while preserving critical functional areas, with careful consideration of load cases, constraints, and mesh granularity to ensure computational efficiency and accuracy. The objectives of the research were to achieve a 20% mass reduction while maintaining or enhancing durability. Our results demonstrate that the desired mass reduction, while maximizing stiffness, was successfully attained. After evaluating various material variants, the 316L material was evaluated as the optimal TO variant.
