摘　　要：采用基于FRUSTUM软件的拓扑优化方法,将有限元法与变密度法相结合,在保证销体强度的基础上,以哑铃销组件的质量最小化为目标,将哑铃销哑铃处位移和最大应力作为约束进行拓扑优化,根据优化结果对哑铃销模型进行二次设计及分析,多次优化迭代后结果表明,优化后哑铃销的质量减轻25%,并且满足强度使用要求。The topology optimization method based on FRUSTUM software was adopted,which combines the finite element method with the variable density method.On the basis of ensuring the strength of the pin body,aiming at minimizing the mass of the dumbbell pin assembly,the displacement and maximum stress at the dumbbell of the dumbbell pin were used as constraints for topology optimization.According to the optimization results,the dumbbell pin model was designed and analyzed twice.The results after multiple optimization iterations show that the optimized dumbbell pin could still meet the strength requirements after its mass is reduced by 25%.
