Influence of Rail Fastener Failure on Vehicle Dynamic Derailment

  title={Influence of Rail Fastener Failure on Vehicle Dynamic Derailment},
  author={Wen Ze-feng},
In order to investigate the effect of disabled fastener system on railway vehicle derailment,a non-symmetrical vehicle-track coupling dynamics model was established.The abrupt change of track stiffness along the track was assumed to simulate the failure situation of rail fastener system.The effect of discrete sleeper support on the coupling dynamics of vehicle and track was taken into consideration.The creepage formulas of wheel/rail rolling contact were deduced,in which the lateral,vertical… CONTINUE READING
