基于横向振动条件下紧固连接的松动机制及影响因素
Loosening mechanism and influencing factors of fastening connections based on lateral vibration conditions
摘要
Abstract
A finite element simulation model of a fastening connection structure under lateral vibration conditions was established using the finite element analysis method,and the effects of initial preload force,load amplitude,load frequency,and rubbing factor on the anti-loosening performance of bolts were studied.The results show that an increase in initial preload force could significantly increase the frictional force on the contact surface,thereby enhancing the anti-loosening performance of bolt connections.However,excessive preload force could cause plastic deformation of bolts,thereby weakening the overall reliability of the connection.The larger the load amplitude,the faster the loosening process of the bolt connection,and the reliability of the connection also decreased accordingly.With the increased of load frequency,the loosening rate of bolt connection significantly accelerated.With the increased of rubbing factor,the anti-loosening performance of threads was significantly enhanced.关键词
