2.
The objective function of this model is the minimized weight, which is subjected to both the buckling constraints and stress constraints.
基于ICM(独立、连续、映射)方法建立了以结构重量最小为目标,以屈曲临界力、应力同时为约束的连续体拓扑优化模型:采用独立的连续拓扑变量,借助泰勒展式、过滤函数将目标函数作二阶近似展开;借助瑞利商、泰勒展式、过滤函数将屈曲约束化为近似显函数;将应力这种局部性约束采用全局化策略进行处理,即借助第四强度理论、过滤函数将应力局部性约束转化为应变能约束,大大减少了灵敏度分析的计算量;将优化模型转化为对偶规划,减少了设计变量的数目,并利用序列二次规划求解,缩小了模型的求解规模。

补充资料:关节屈曲线


关节屈曲线
joint flexion line

一般指小指第一、二关节的屈曲线,通常不止一条,若小指短而内屈,关节屈曲线只有一条,常为先天愚型的表现。
