Abstract:

?针对某多管火箭炮(MRLS)复合材料定向管的结构设计指标,根据有限元分析方法和优化设计方法,以复合材料定向管的复合铺层厚度、铺层角度及定向管中定位部的位置为优化设计变量,定义定向管固有频率和定向管质量为优化目标,结合有限元数值计算结果,采用改进非支配排序遗传算法(NSGA-Ⅱ),建立了复合材料定向管的多目标优化模型。通过优化求解,得到帕雷托(Pareto)最优解,并由这些Pareto最优解构成决策矩阵,利用客观赋权的信息熵法计算各属性的权值,并运用逼近理想解的排序方法(TOPSIS)进行了多属性决策研究(MADM),对Pareto最优解作了排序。引入比刚度结构效能对比分析优化前后的定向管性能,表明对定向管的优化设计是有效的。
