| Abstract: | Pre-tightening force of high strength bolt should be correctly set in order to improve the con- nection quality, fully exploit the potentiality of material strength, avoid unnecessary waste of material and reduce manufacturing cost. This paper introduces the relationship between pre-tightening force of high strength bolt and friction coefficient of thread surface based on the stress state of bolt and the theory of material strength. |
