摘要
用Monte carlo统计模拟方法对火箭发动机固体推进剂随环境温度变化的力学性能进行了分析,提出了力学性能的可靠寿命仿真计算的方法,并对延伸率的老化可靠寿命进行了计算。
The variation of mechanical properties of a solid-propellant in rocket motor with environmental temperature was analysed by means of Monte Carlo statistical simulation method in the paper.A reliability calculation model of properties for aging and a reliable life calculation method were suggested.
