本文主要讨论了火箭炮在发射火箭弹过程中所受冲击力的随机特性,导出随机冲击力的均值和方差(协方差)随时间变化的关系式.从这些关系式出发,对各时间段影响火箭弹散布的各随机因素进行了较深入的探讨,使各随机因素对冲击力的贡献进一步量化,为火箭炮可靠性设计及随机响应模拟提供必要依据.
This paper mainly discusses the random characteristics of rocket launchers in the process of launching rocket launchers and derives the relationship between mean and variance (covariance) of random impulses with time.From these relations, Explored the various random factors scattered in the missile and made the contribution of each random factor to the impact force further quantified, which provided the necessary basis for the reliability design and random response simulation of rocket launchers.
