Abstract

Abstract

A mechanical model and its software based on the finite element principle were presented, the additional longitudinal force and displacement of the welded turnout combination system were discussed. With an example, the influences of track parameters on rail displacement and longitudinal force of the combination system and single welded turnout were calculated, and the results were analyzed.The results show that the ballast resistance has a stronger influence on the welded turnout combination system than that of the single welded turnout, the influence of fastener resistance and the gap limit of spacer pieces is almost the same; the fastener resistance has a little more but the gap limit of spacer pieces has a little less influence on the welded turnout combination system than that of the single welded turnout.
