| 摘 要： | 提出结构钢光试样等寿命曲线方程，并提出用等寿命曲线方程绘制结构钢光试样等寿命图的新方法．只要测得材料在对称循环（r＝－1）下的S-N曲线，就可以用等寿命曲线方程绘制材料的等寿命图．用等寿命曲线方程绘制等寿命图与传统的方法相比，可减少60％～70％的疲劳试验．

| Abstract: | The constant life fatigue curve equation for structural steel smooth specimens is presented. Based on the equation, the article presents a new method by which constant life fatigue diagram of structural steel smooth specimens can be obtained, so long as material data for S-N curve of symmetry cycle (r = -1) are determined. When compared to traditional method, constant life fatigue diagram based on constant life fatigue curve equation can reduce fatigue tests by 60%～70%. |
