等幅循环载荷作用时零件疲劳可靠度尺寸的计算方法

The computation method of mechanical part's dimension with given fatigue reliability under the affection of constant amplitude circulatory load

本文根据现有的疲劳理论,提出了等幅循环载荷作用时,零件疲劳可靠度尺寸的计算方法,与常用的方法相比,这种方法计算量小,运用更方便,适用性更强。

According to the available fatigue theory this paper presents a computation method of mechanical part's dimension with given fatigue reliability when the part is under the affection of constant amplitude circulatory load. As compared with the conventional method, this method has the advantage of less computation, easier use and more suitability.
