摘要： 在分析冲压模具结构的基础上，提出了冲压模具结构拓扑优化方法，建立了以减重为目标的高强度钢板压边圈优化设计方法，并以DP590轿车侧向高强度双向钢底板拉深压边圈为例加以验证.结果表明：与按准则的设计相比，采用拓扑优化设计的压边圈可以减重50%，且其结构的关键位移及最大应力均未受到影响。

Abstract: Based on die structure analysis, an SIMP based die structure topology optimization model was proposed. An optimal design method for binder part was established, aiming to reduce die weight. Optimization of binder structure of a floor member part of DP590 was studied. Compared with current design, optimally designed binder can reduce 50% weight. And the critical displacement and maximum stress are not affected.
