| 摘 要： | 基于Tsai-Wu失效准则和一次二阶矩法,建立了复合材料定向管强度可靠性分析的方法。应用Python语言实现了ABAQUS 的二次开发,编程将有限元计算程序与可靠性分析方法相结合,并采用多岛遗传算法和序列二次规划算法相结合优化策略,建立了基于可靠性的定向管铺层参数动态优化模型。优化算例表明:在满足强度可靠度条件下,复合材料定向管重量减小了22.5%。

| Abstract: | Base on the Tsai-Wu failure criterion and first order reliability method(FORM),the reliability analysis of a composite material direction pipe is carried out.Secondary development of ABAQUS by using Python language,the finite element program and the reliability analysis method are combined.The reliabilitybased optimization model of a composite material direction pipe is obtained by the combined optimal strategy with multi-island genetic algorithm(MIGA) and sequential quadratic programming(SQP).The results of an example application show that the weight of the composite material direction pipe decreased by 22.5% with the requirement of strength reliability. |
