摘要
通过对固体火箭发动机贮存失效规律分析,将指数分布和威布尔分布结合,建立了一种新的失效率优化模型,并对实际贮存发动机的寿命可靠性进行了计算。计算结果表明,用失效率优化模型计算的寿命较好地反映了发动机实际贮存的真实情况,从而为贮存发动机寿命可靠性计算提供了一种新的实用计算方法。
Through the failure rule analysis of deposited solid rocket motor, an optimized failure probability model was established based on the combination of exponential distribution and Weibull distribution, and was used to calculate life reliability of naturally deposited solid rocket motor. The calculated results show that the calculated storage life using optimized model agree well with the actual condition, and a new practical calculated method is provided for life reliability of deposited solid rocket motor.
