摘要
运用“等效”理论，将非正态分布在设计点处转换为一个等效的正态分布，然后用一次二阶矩的迭代法求解可靠度．该法适用于各种分布之间的干涉解．本文着重研讨了对数正态分布和威布尔分布的等效正态分布．
Using equivalent principle. a non-normal distribution can be converted into a normal distribution at design point. The reliability then can be solved with the iteration of the second-order moment. The method applies to the interference solving of various distribution. This paper discusses the equivalent normal distribution of logarithmic normal distribution and weibull distribution.
