摘要
本文论述了在疲劳可靠性分析和设计中求P-S_a-S_m-N曲面的必要性,探讨了P-S_a-S_m-N曲面一般形式的选择原则,提出了矩法和最大似然法两种疲劳试验方案,分别给出了根据试验所得的疲劳性能数据求P-S_a-S_m-N曲面的方法,并用实例加以说明。
: The necessity of getting P-Sa-Sm-N curved surface in the fatigue reliability analysis and design is discussed, and the principles for choosing the P-Sa-Sm-N curved surface are given. Two different approaches (moment method and maximum likelihood method) for fatigue tests are presented, and the methods are respectively suggested by which the P=Sa-Sm-N curved surface could be obtained from the data of the above two kinds of fatigue tests.
