Abstract:In order to accurately explore the loosening characteristics of bolt connection under transverse vibration conditions, this paper comprehensively considered the influence of local slip and torque slip, established a bolt connection model considering inertial force, analyzed the forces at different positions of the screw threads, and obtained a theoretical calculation method for calculating the critical loosening load of bolts, which is verified by the transverse vibration test. The results show that the theoretical calculation method has higher accuracy. The critical loosening load of bolts under different parameters such as preload, friction coefficient of thread surface, vibration number, pitch, vibration frequency and thread rise angle is quantitatively calculated, and the main influencing factors of bolt loosening are revealed. When the preload and friction coefficient of thread surface are increased and the vibration number, pitch, vibration frequency and thread rise Angle are reduced, the critical loosening load of bolts will increase, which is conducive to improving the anti-loosening ability of bolt connection against self-loosening. The research results have a guiding significance for the design of bolt-joint locking.
