| 摘 要： | 将纽曼级数展开的蒙特卡罗随机有限元应用于具有随机因素的纤维缠绕结构的应力求解；然后利用蒙特卡罗直接比较法和蔡希布（Ｔｓａｉ－Ｈｉｌｌ）失效判据给出该结构的可靠性算式，最后建立了此类结构的可靠性优化设计迭代法，并给出了一算例。

| Abstract: | Neumann series expansion in Monte-Carlo finite element is used to find the stress of fiber winded composite structures with stochastic factor; Structure reliability formula are then given by Monte-Carlo comparison method and Tsai-Hill failure criteria. Finally, iterated algorithm in reliability optimization design for the structure is provided and an example is shown. |
