摘要
建立了一类系统受冲击损伤的数学模型,在系统工作环境承受冲击损伤的到来服从几何分布、冲击引起的损伤服从指数分布的条件下,讨论了系统损伤未达到危险临界值的概率、平均损伤、引起系统失效的冲击次数的均值及系统损失效率等相关可靠性指标。
Established a mathematical model of system impact damage. Under the conditions that system working envi- ronment absorbing the coming shocks obeys geometric distribution and impact damage obeys the index distribution, discussed the related reliability index of the probability of risk threshold z of the system, the average risk, the mean number of shocks caused the system failure and the efficiency of system losses.
