摘 要: | 本文在不同材料疲劳试验结果的基础上,分析了不同材料的平均载荷对疲劳交变载荷的影响,其等效载荷的修正呈现出不同的曲线线性.文中通过引入Haigh系数,统一了等寿命曲线分析中等效载荷的Goodman/Soderberg/Gerber修正方法,并给出不同材料平均载荷对等效载荷影响的修正曲线的系数.

Abstract: | According to the fatigue test results of different materials,the effect of mean load on fatigue strength are different,and the modified fatigue load are different.This paper supposed a Haigh factor to combine the modified method of Goodman/Soderberg/Gerber,and provided the different Haigh factors of different materials. |
