摘要
通过对 0 9V钢乙形型材母材及其焊接接头Goodman疲劳极限线图试验的研究 ,获得了具有一定存活率和置信度的P -S -N曲线以及修正的Goodman疲劳极限线图。为进行非对称循环条件下的抗疲劳设计 。
A processing method of experimental analysis of Goodman fatigue Diagram is presented in this paper by concluding the research work of the Goodman fatigue diagram of 09V steel and its welded specimen. This processing method of experimental analysis of Goodman fatigue diagram is also fit for the other engineering metal materials.
