rail tie plate as an important part of the railway line, the principle is to use a rod to connect two rail, improve the lateral stability of the rail and the ability of the track to maintain gauge; Other lines have track circuits separated by insulation in the middle of the rail tie plate.

If the rail tie plate is missing, it will lead to the wrong gauge, and the train traveling to this section will lead to the derailment of the train, and then it may lead to the subversion of the train, the consequences are unimaginable.

Switch structure is very complex, short life and traffic insecurity, maintenance and maintenance is also very laborious, is one of the three weak links of track structure, if often maintenance or replacement of switches will seriously affect the normal operation of heavy haul railway;

On the basis of the rigid-flexible coupling method, a refined vehicle is established as a model for the dynamic analysis of switches. Combined with the test results, the reliability of the model is checked. The data obtained from the model is used to analyze and study the influence law of the crossing mode, running speed and dynamic characteristics of the switch system.

1. When 20 groups of rail tie plates are set on the side stock, the wheel-rail transverse force can be reduced by 43.0% at most, and the wheel-rail vertical force can be reduced by 5.1% at most, and the more the number of gauge rods, the indicators will also be reduced. According to the index factors, it is suggested to set 10-14 groups of rail tie plates on the side bone lines of the turnout area.

2. It is recommended to reduce the wheel-rail force by using 1:20 rail bottom slope, so that the effect is more significant, in which the wheel-rail transverse force can be reduced by 14.8%, and the wheel-rail vertical force can be reduced by 16.7%.

3. When the section width is increased by 2mm, the wheel-rail force and contact stress increase can reach 8.3%, and the eastern bending stress of the corresponding section of the rail decreases by 18.8%. Therefore, it is recommended to increase the thickness by 2mm to optimize the bearing section of the core rail and the switch rail.
