Topology Optimization of Battery Bracket for Electric Vehicle

【Abstract】In order to reduce the weight and cost， the topology optimization method based on variable density method was used to carry out multi-objective topology optimization of the battery bracket. The optimization results show that the mass of the optimized battery bracket has been reduced by 16.7%， and the structural performance meets the design requirements， which has been verified through vehicle road tests. The optimization process shows that topology optimization provides a fast and effective solution for lightweight design of structures.
