| 摘 要： | 本文在疲劳寿命分布研究的基础上，对疲劳强度分布特性进行了研究。利用疲劳寿命分布与疲劳强度分布间的转换关系进行转换，发现疲劳强度的分布不是通常假设的正态分布，而是偏态分布。并根据寿命分布与强度分布作出了疲劳失效概率的P－S－N三维空间曲面，这在理论上和工程上均有重要价值。

| Abstract: | Based on the study results of the fatigue life distribution, the fatigue strength distribution characteristics of a HSLA steel was studied in this paper, and the fatigue strength distribution has been derived from the conversion relationship between the fatigue life distribution and the fatigue strength distribution. Research results show that the fatigue strength distribution is not normal but skew. For the above distributions, the P-S-N space curved surface which expresses the fatigue failure probabitity was drawn, and the curved surface will play an important role not only in practice but also in theory. |
