基于SFEM的SRM纤维缠绕结构的可靠性分析

Reliability Analysis for Fiber Winding Chamber of Solid Rocket Motor via Stochastic Finite Element Method

采用纽曼级数展开的蒙特卡罗随机有限元方法(SFEM),分析了固体火箭发动机(SRM)复合材料缠绕的燃烧室在内压正态变化下的应力响应,然后利用应力强度干涉原理分析计算其可靠性。

Adopt extended Neumann stochastic finite element method （ SFEM ） to analyze the stress response of the fiber winding chamber of solid rocket motor （ SRM ） under the action of gas pressure with normal distribution, then analyze and compute the its reliability according to the stress strength interference principle.
