Abstract:The structural instability caused by the loosening of bolts of the sound barrier of high-speed railways has become an important reason affecting its safe use, but there is still a lack of basic research on the possible structural vibration of the sound barrier when the bolts are loosened. In this study, a finite element model of the sound barrier of high-speed railway was constructed, and the vibration mode simulation analysis under different bolt loosening conditions was carried out. The results show that the… Show more
