摘　　要：基于逆向工程与拓扑优化技术完成了支座的轻量化设计。首先通过逆向工程建立起支座三维模型;其次,通过静态有限元应力分析给出优化的约束条件;然后以最小体积分数为优化目标,以最大Von-mises应力和最大位移为约束,以单元密度为设计变量完成支座的轻量化设计。结果表明,在满足所有约束条件下,优化后的支座质量降低了近18%,效果较好。The lightweight design of support is completed based on reverse engineering and topology optimization technology. The three-dimensional model of the support is established through reverse engineering. The optimization constraints are given through static finite element stress analysis. Then the lightweight design of the support is completed with the minimum volume fraction as the optimization objective, the maximum von-Mises stress and the maximum displacement as the constraints, and the element density as the design variable. The results show that the quality of the optimized support is reduced by nearly 18% under all constraints.
