摘要
在以应力和强度均呈正态分布的前提假设条件下 ,归纳提出了计算机械零件可靠性统计量的三个基本方法——代数法、矩法和变异系数法 ,比较了三种方法的计算精度 。
With the assumption that the set of basic variables of stress and strength is normally distributed, three basic methods for computing reliability statistical value of machine element(algebra method,moment method,variant coefficient mothed) are generalized In the mean time , the computing precision of the three methods are compared,and their respective characteristics and application are pointed out
