摘要
为实现再入体结构轻量化设计,开展了旋转惯性过载作用下再入体结构拓扑优化设计技术研究。本文利用灵敏度"逻辑与"综合方式的多工况结构拓扑优化设计方法,结合惯性载荷作用下拓扑灵敏度分析,研究了旋转惯性过载作用下再入体结构拓扑优化设计。针对锥筒形支架结构,以整体刚度最大化为目标函数,材料用量为约束条件,进行了结构拓扑优化设计,得到了合理的优化构形。
The topology optimization of continuous structures with rotary inertia loads was investigated in this paper,using the method of the topology optimization of structure convert into topology optimization of multiple load cases.The logical AND scheme is used to combine multiple load cases,the elimination sequence of an element depends on its highest relative reference value among all load cases.The work focused on problem considering rotary inertia loads.Evolutionary procedure for this problem of rotary inerti...
