传动机构零部件疲劳设计的标准载荷谱

Standard load spectrum in fatigue design of part and component of a drive unit

本文对GB3811-83起重机设计规范存在的一些有关传动机构疲劳没计标准载荷谱的具体疑难问题进行了探讨。包括:零部件分类方法,载荷时间历程中载荷分离法,疲劳计算载荷的计算原则,构成疲劳载荷谱的要素以及应力循环次数计算法等。

Present paper studies some concrete difficult problems related to standard load spectrum in fatigue design of a drive unit according to crane design regulation GB3811-83, including classification method for parts and components, load separation in load-time history, principle in calculating fatigue load, main composite factor in fatigue load spectrum and calculation of stress cycle number etc.
