防止螺栓联接失效的计算方法

Calculating Methods for Preventing Bolt Linkage Inactivation

微动磨损会引起螺栓联接失效。文章分析了微动磨损下螺栓联接失效的原因,基于螺栓轴向弹性变形及接触面上的粗糙峰被碾平等因素,提出了防止螺栓联接失效的计算方法和公式。

The inching abrasion can cause the bolt linkage inactivation. This paper analyzes the reasons of the bolt linkage inactivation under the inching abrasion and, based on the factors such as bolt's axial elastic deformation, flattening-out of rough peaks on contact surfaces, etc., puts forward some calculating methods and formulae for preventing bolt linkage inactivation.
