Brief Discussion of Checking Fatigue Strength of Bolts

螺柱的疲劳分析 ,首先需确定螺柱承受循环载荷的交变应力强度幅。本文对其计算原理和方法作了介绍 。

In order to carry out the fatigue analysis of the bolts, it is necessary to determine the changing range of the stress intensity in the bolts due to the cycle load. In this paper, the calculation method for the changing range of the stress intensity in the bolts was introduced. At the same times, the practice example was used to analyze the key points in carrying out the fatigue design of the bolts.
