Abstract:

The conventional reliability models can’t reflect the effect of times of random loading on the reliability and the contribution of random load to the failure rate, especially, to the early failure rate is covered. In this paper, according to the statistical meaning of random loading， the reliability model is developed with the order statistics theory for the component under repeated loading.

Key words: reliability , model,  , failure , rate,  , component , reliability,  , times , of , loading,  , timedependent , reliability
