用模拟试验法对 P-S-N 曲线试验方案的分析

An analysis on the test scheme of P—S—N curve by the use of simulated testing method

本文针对材料的Ｐ—Ｓ—Ｎ曲线测试过程的设计，采用ＭｏｎｔｅＣａｒｌｏ法进行模拟试验，在试验的应力级数、每级试件数、，时间与精度上进行分析，确定出最佳试验方案，从而减少了大量的试验时间和试件。

Aimed at the design of testing procedure for the P—S—N curve of materials this paper adopted the Monte Carlo method to carry out a simulated test and conducted an analysis on number of stress levels in the test,number of samples for each level,testing time and its accuracy in order to determine an optimum testing plan.Thus reduces greatly the testing time and number of samples.
