摘要
分析了受拉螺栓的应力与变形，指出这种螺栓的强度失效的主要原因是应变疲劳破坏，进一步在探讨应力-应变统计特性的基础上，提出了确定螺检应变疲劳可靠性寿命的方法，因此方法可进行螺栓可靠性寿命的预测。
In this paper, stress and strain of bolt under axiat loading are analysed. It is explained the the main cause of bolt failure in strength is strain fatigue. Then, the statistical characteristics of stress and strain are discussed. Finally, a method for strain reliability of bolt is presented, and the reliability fatigue life of the bolt can be prestimated.
