【摘要】 基于连续体ICM拓扑优化方法,笔者提出了不在体积约束下的多阶频率加权和为目标函数,考虑非设计集合的拓扑优化方法。在CAD/CAE设计系统中,针对高速立式加工中心的动态特点,确定加工中心的关键结构件立柱为优化对象,并考虑其它重要零件影响。根据此方法设计的高速立式加工中心立柱,使得整机动态特性有很大提高。更多还原

【Abstract】 According to ICM(independent-continuous mapping) topology optimization theory,a new topology optimization method considering undesigning aggregates is proposed in this paper.The constraint function is volume of structure,and the objective function is the weight of the first nature frequencies.In CAD/CAE designing system,to the whole CNC dynamic characters,pillar is taken as the optimal object with considering the influence of other important components.Optimized CNC pillar improves whole CNC dynamic characters noticeably.更多还原
