摘要
本文提供了５１ 种国产机械材料的Ｓ－ Ｎ 曲线表达式，研究了零件Ｓ－ Ｎ 曲线的系数ａ 、ｂ 和转折点寿命Ｎ０ 的确定方法，推导出了ａ 、ｂ 的计算公式，给出了理想化Ｓ－ Ｎ 曲线的合理表达式。
This paper provided the S-N curve expressions of 51 kinds of Chinese made machinery materials, studied the coefficients a and b of component's S-N curves and the determination method on life No corrcsponding to kickpoint. It derived the calculation formulas for a and b and presented the reasonable representations of idealized S-N curves.
