Abstract
The bolted joint is the important fastening parts of structures. Its fatigue and self-loosing will affect the safety of the system. In this paper, the finite element contact models are built to analyze the mechanical property of bolted joint numerically. The stress, strain and clamping force when the bolted joint is subjected to preload, axial force and transverse load are investigated. The results show that the bolt is the most dangerous part of bolt-nut connected member. The clamping force of bolted joint will gradually lose with the increasing loading cycles of cyclic transverse load which generally explains the stress loosing rule of bolted joint.
