Abstract
Based on field tests in a curved section of Shanghai-Nanjing high-speed railway, a research on performance variation of self-loosening of WJ-7B fastenings was carried out such as the preloaded force and the changing law of axial force. The calculation of preloaded force of anchor-fixing bolt and rotation angle is used to analyze the tendency of self-loosening. Furthermore, setting proper maintenance intervals for tightening to ensure the long-term safety of train operation is important.
