Research on Continuum Structure Topology Optimization Based on Bi-Directional Interpolation Model

  • 摘要: 针对传统拓扑优化中对中间密度单元处理的单向(惩罚)性,提出一种由阈值决定中间密度单元处理方式的双向插值模型(Bi-Directional Interpolation Model, BDIM),建立基于BDIM模式的优化模型。利用拓扑优化梯度投影法,结合算例,对比分析传统插值模型、只对敏度进行双向插值模型和同时对刚度和敏度双向插值模型优化。结果表明,只对敏度进行双向插值模型具有无需过滤、全局收敛、边界清晰的多重优点。
