摘要
分析了区间分析方法在包含界约束拓扑优化问题中使用的可行性。根据区间敏度分析优点与传统敏度分析的不足,将区间敏度分析思想引入结构拓扑优化设计中,建立了子区间基(中心)移动拓扑优化方法,并用数值实验验证了该方法的可行性及有效性。
Characteristics of interval sensitivity analysis method were studied and teaslbihty ol Introducing interval sensitivity analysis method to topology optimization of bound constrained was ana- lyzed. According to the merits of interval analysis and shortcomings of traditional sensitivity analysis, a topology optimization method of moving sub-interval center method was established. The feasibility and validity of the method was verified by a numerical experiment.
