针对复合材料加筋壁板的稳定性优化问题提出了一种用混合罚函数法、Powell法、黄金分割法、改进的坐标轮换法和遗传算法相结合的混合优化算法。并通过优化程序实现了以加筋板的屈曲载荷最大为目标的优化设计,最后通过算例验证了优化方法的有效性,同时对优化结果进行了深入地分析。得到的结论对加筋板的设计有一定的指导意义。

Directed against the problem of stability optimal design on reinforced wainscot of composite materials a kind of mixed optimization algorithm with the combination of mixed penalty function method, Powell method, golden section method, improved coordinates alternation method and genetic algorithm was put forward. The optimization design that takes the flexural load of the reinforced boadr to be a maximum as the target was realized by means of optimization program, and finally the effectiveness of the optimization method was testified through example of calculation and a deep going analysis was carried out at the same time on the optimized result. The conclusion obtained possesses certain guiding significance on the design of reinforced board.
