介绍一种疲劳强度评估方法

Introduction of a Method of Evaluating Fatigue Strength

从随机变量分布的概念出发,介绍一种疲劳强度的评估方法,并以正态分布为例,给出具体计算步骤。此法所得结论稳定,不会因个别数据的取舍而产生明显的波动,用于经常性的成品货源鉴定,可以节省时间和试样。

Starting from the idea of randon variable distribution, a method of evaluating the fatigue strength is introduced, and taking normal distribution as an example, steps of actual calculations are given out. Results of this method are stable and will not be influenced materially by cancelling or taking some individual data. So it is suitable for use in evaluating finished products delivered consistently from a source, and it will save time and samples.
