摘要
本文采用计算机模拟的方法, 通过对10 余种材料进行模拟分析得出: 在用升降法测定材料的疲劳极限时, 应力级差的选取范围在材料的疲劳极限的2 % ~6 % 之间比较合理,
In this paper ,the authors adoptthe method of computerimitation ,and through studying over a dozen materials,draw the conclusion : when using Up - down method to determinethefatiguelimit of ma terial,the stressincrementis selected at range from 2 % to 6 % of the fatigue limit,and the disperse has importantinfluence on the precision offatigue limit .
