摘要
采用蒙特卡罗随机有限元方法，结合复合材料壳体力学、纤维缠绕理论等知识，分析了固体火箭发动机纤维缠绕壳体在燃气内压随机变化作用下的应力响应，绘出应力分布曲线，为固体火箭发动机结构可靠性评估奠定基础。
Analyzed the stress response under the action of gas pressure according to random variation for the fiber winding shell of a solid rocket motor by using the method of Monte Carlo stochastic finite element and combining with shell mechanics and fiber winding theory of composite material.The curves of stress distribution were given,which laid a foundation for the reliability estimation of solid rocket motor structure
