损伤可加冲击模型的可靠性指标

Reliability Index of Shock Model with Increasing Damage

研究了Poisson-Geometric过程的性质,针对损伤次数分别为泊松过程及Poisson-Geometric过程的冲击模型,在损伤可累加的情形下,研究了期望损伤、可靠度和平均寿命等可靠性指标。

The properties of compound Poisson-Geometric process were discussed. The shock models with the impact number of times obeying the Poisson process and Poisson-Geometric process are studied. The reliability index such as the expectation damage, reliability and the average life span are explored in order to provide the basis for the system life.
