摘要
文章叙述了一种高强度螺栓拧紧工艺设计方法。以汽车前减震器与转向节连接螺栓为例,通过采用计算校核结合扭矩测试及夹紧力测试,对拧紧工艺进行正向设计开发,确定了最佳拧紧策略及工艺参数。该方法可推广使用到其他关键连接部位拧紧工艺的开发上,对保证在服役条件下紧固连接的可靠性有重要的意义。
The design method of high strength bolt tightening process is presented. Taking the front shock absorber and the knuckle connecting bolts as an example, through the use of calculation and verification, combined with the torque test and the clamping force test, the tightening process is developed in a forward direction. The best tightening strategy and process parameters is determined. The method can be used to the development of the tightening process of other critical joints. It is significant to ensure the reliability of joints under service conditions.
