Spatial Coupling Vibration Properties of High-Speed Vehicle-Turnout

  • Received Date: 09 Jan 2008
  • Publish Date: 25 Aug 2008
  • 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.The research results show that the impact between wheel and rail is more exquisite at switch than at frog;the contact force between wheel and rail and the acceleration of a vehicle have 4 peak values;compared with switch rail and point rail,stock rail has a small acceleration,but the attenuation of its acceleration is fast;the vertical force transferred by spacer block is bigger than that transferred by rail fastening.
