一种可靠度计算的离散方法

Approach of Reliability Computation

机械系统的应力和强度往往是ｎ维随机变量的函数，可靠度难以求出。本文提出的离散方法，将大大减轻计算负担。通过蒙特卡罗模拟，证明这种方法在计算复杂系统的可靠度上，不仅简单，而且精确。

The functional relationship is usually complex when the random variables composing the strength and stress of a given system are n normal.As a result,it is difficult to accomplish the reliability.The descretizing approach presented in this paper significantly reduces the computational burden.The Monte Carbo simulation proves that it is an accurate and simplified approach for the reliability computation.
