| 摘 要： | 采用遗传算法进行复合材料层合板的铺层顺序优化设计，即采用整数编码方式，并对解码进行特殊处理以满足平衡铺层要求；通过父代与子代竞争延长了父代个体寿命，使优良基因有更多机会遗传给下一代；遍历所有分析过的个体信息以减少计算量，算例表明，改进的遗传算法是有效的。

| Abstract: | The genetic algorithm (GA) is applied to the stacking-sequence optimization of composite laminate plates. The integer-coded is adopted, and the encoding is dealt with particularly to make individuals generated to meet the balanced-layer requirement. The competition of parents and offspring prolongs the life span of parents and good genes are given more chances to be inherited. All information about individual calculated are compared with that of individuals generated afterwards, which decreases the computational expense. The numerical examples show that GA is convenient and effective to deal with this kind of the special problem with discrete variable, aiming at the optimum stacking-sequence design of laminate plates. |
