药柱结构完整性的可靠性分析

Reliability Analysis on Structural Integrity of Propellant Grains

在药柱结构应力分析和推进剂伸长主曲线处理的基础上 ,讨论药柱结构完整性、可靠性的计算方法 ,并对计算结果与传统的安全系数方法进行比较 。

Based on the structural stress (stain) analysis of grains and the treatment of the master elongation curve of propellant, the reliability analysis methods of the structural integrity of solid propellant grains are discussed. In comparison of the calculated results with those given by the traditional methods of safety factor, the tendencies are identical.
