交变温度作用下推进剂耗散能与累计损伤的数值计算*

摘要

By numerical calculation of dissipated energy and accumulated damage factor of propellant under alternating temperature loads ,the numerical values of dissipated energy and accumulated damage value of propellant under different loads conditions have been gotten .A new basis platform have been provided for the research of correlativity for accelerated aging process and natural storage life of solid rocket engine .A reference for the new methods of the life prediction of the solid rocket engine have been provided .%通过推进剂在交变温度作用下损耗能和累积损伤因子的数值计算，得到了不同载荷条件下推进剂的耗散能和累计损伤值，为固体火箭发动机加速老化过程与自然贮存相关性研究提供新的基础平台，为固体火箭发动机寿命预估新方法的探索提供参考。
