Abstract :
This paper establishes the finite element model of continuous welded rail with the minor radius curve and infers the corresponding value formula. Using this finite element model, this paper analyzes the influence of dynamic and static load on the stability of continuous welded rail with the minor radius curve, which indicates that the model can be used to simulate more accurately the actual situation of the track lateral displacement due to the ambient temperature changing and dynamic load (unbalanced centrifugal force and vertical vibration force caused by track irregularity) effect.
