| Abstract: | A finite element model of the No.41 seamless turnout was built up by the hnlte element method and parameterlzed modeling technique of finite element general software ANSYS APD. The forces and displacement of seamless turnout were calculated, the influences of some parameters on the rail displacements and longitudinal force of seamless turnout were analyzed, such as the sleepers of turnout, the spacing restricting device, the spacer block of the frog heel and the fastening resistance. The results could be used to guide the design of large number seamless turnout |
