燃烧室压强随机分布的模拟及响应

Simulation and Response of Stochastic Pressure of SRM Chamber

采用混合同余法与变换抽样法对固体火箭发动机纤维缠绕燃烧室压强的多种随机分布进行了模拟，并结合蒙特卡罗随机有限元方法分析了该结构在正态分布压强作用下的力学响应。其结果可用于此类结构的可靠性评估与设计。

Several stochastic distributions of chamber pressure have been simulated by mixed congruence method and conversion sampling method. SRM chamber structure mechanics response under the action of normal distribution chamber pressure has been analyzed by used of Monte Carlo stochastic finite element method.The simulation result can be used in the evalution and design of SRM structure reliability.
