| 摘 要： | 本文针对承受高频小载的稳态循环疲劳载荷的结构具有长寿命这一特点，采用二维应力一强度干涉模型进行疲劳可靠性分析。给出了疲劳载荷统计处理研究结果，提出了由Ｐ－Ｓａ－Ｓｍ－Ｎ曲面确定疲劳强度分布函数的理论计算公式，并给出了二维应力－＝强度干涉模型的应用实例。

| Abstract: | Under the steady small cyclic load with the high frequency, the component will have longlife, so the two-dimensional stress-strength interferace model has to be used to analyse its fatigue reliability. In this paper, the treatment result of the fatigue load spetrum is given. By means of the P-Sa-Sm-N surface, the formula to determine the fatigue strength function is presented. finally, a example is given. |
