Effect of gauge widening of switch on dynamic characteristics of high-speed turnout;

Technical studies on high-speed turnouts for china railways

To provide a theoretic reference for the design of high-speed turnout,the contact force between wheel and rail and the vibration properties of a vehicle-turnout coupling system were analyzed by using the spatial coupling vibration theory for high-speed vehicle-turnout,and the structure irregularity of high-speed turnout was used as the vibration excitation.
