| 摘 要： | 针对复合材料梯形波纹夹层板的优化设计,提出了一个三步优化方法。第1步和第3步以结构质量为目标函数,使用广义简约梯度法进行尺寸优化,第2步以临界载荷为目标函数,使用遗传算法进行铺层优化。最后通过算例验证了优化策略的有效性。

| Abstract: | A three-step optimization method for typical composite sandwich structure with a trapezoid corrugated core was developed.In the first and the third step,Generalized Reduced Gradient Method was used for size design optimization.In the second step,Genetic Algorithm was adopted for stacking sequence optimization to improve critical load.An example was given to demonstrate the availability of the method. |
