对某重型车桥桥壳在设计工况下的静强度性能进行了有限元分析，并对该桥壳结构进行了轻量化设计。采用拓扑优化方法，以初始设计作为优化的基结构，以重量最轻为目标函数，以结构的静强度性能为约束条件，进行了优化迭代计算。轻量化设计后，减轻了桥壳的重量，且轻量化结构满足强度要求。

Finite element analysis was performed on the static strength properties under design conditions of a heavy axle housing, and lightweight design was performed. Using topology optimization method, iterative calculations for optimization were performed, the original design was taken as the base structure of optimization, the lightest weight was taken as the objective function, the structural static strength properties was taken as the constraints. After the lightweight design, the housing weight was reduced, and the lightweight structure met strength requirements
