Estimation and Analysis for the Fatigue Life of Rail Joint Bolt

摘要：

　　One of the most important reasons for railway traffic accidents is the fatigue failure of the rail joint bolt.Therefore,the research on the fatigue properties of rail joint bolt has important practical significance.This paper analyzed the influence of different pre-tightening torque on the fatigue life of the rail joint bolt.Besides,the best pre-tightening torque of the bolt was acquired through theoretical calculations.Finally,the fatigue life of the rail joint bolt was predicted according to the relevant basic theory and methods of fatigue life analysis,which applied numerical simulation technology.
