| 摘 要： | <正> 常规的优化设计是以定值量作为设计变量,仅以一个笼统的安全系数来描述客观存在的各种不同的随机性。可靠性基础上的优化设计是以随机变量作为设计参量的,所以能更好地反映结构实际的安全程度。可靠性基础上的铺层优化设计是以满足可靠度指标要求为约束,得到在满足可靠度指标要求下的最优层组分布。

| Abstract: | Under generalized loading a method of optimum design for a composite laminate is presented. The optimum ratios of ply groups of laminate satisfying allowable reliability are obtained. The design objective is the weight of laminate and to satisfy the special requirement of laminate. It is shown by examples that this method is very efficient. |
