复合推进剂交变温度作用下应力应变数值分析

Stress-Strain Analysis of Composite Propellant under Alternating Temperature Loads

摘要:

文章以某导弹发动机使用的复合固体推进剂为研究对象,采用热粘弹性有限元法分析了复合固体推进剂在交变温度载荷作用下的应力应变情况,给出了应力应变场的分布规律,判断了推进剂药柱容易失效的部位,为固体火箭发动机寿命预估新方法的探索提供参考。

Abstract:

Because of the big difference between High-Temperature accelerated aging and natural storage, the composite propellant under alternating temperature loads was analyzed with finite element method. The stress and strain distribution were obtained, which provided reference for SRM life prediction.
