摘　　要：运用相对密度法,以最大位移和模态频率为约束,并添加工艺约束,对钻床的底座进行拓扑优化;根据拓扑优化的结果进行加强肋的布局,并对优化结果进行静力、模态、谐响应分析,以验证优化结果。With max-displacement and modal frequency constraints and processing constraints, this paper makes topology optimization of a drill base using relative density; According to the optimization results, the layout of stiffening ribs is determined, then static, modal and harmonic analysis of the optimized model are done to prove the optimization results.

关 键 词：相对密度法 拓扑优化 加强肋的布局 模态 谐响应分析
