Taking the antenna bracket structure of a rail vehicle as the research object,OptiStruct software is used to perform topological optimization and size optimization design on the antenna bracket structure,and the relevant optimization process and results are specifically explained and analyzed in this paper.According to the relevant standards of EN 12663,the optimized antenna bracket structure is simulated and verified,and the results show that the strength meets the standard requirements.The new antenna bracket structure reduces the weight by 68.1%compared to the original structure,and the optimization results are ideal.The lightweight method of antenna bracket structure proposed in the paper achieves the goal of reducing the total weight of the bracket,minimizing material usage,and lowering production costs.
