Application of Vehicle-Track Coupling Dynamics to Study on Settlement of Railway Tracks

  • Received Date: 30 Jun 2006
  • Publish Date: 25 Aug 2007
  • Dynamic characteristic of track settlement was investigated by combining the vehicle-track coupling vibration model and the track settlement model,and the dynamic response parameters of track structure and the irregularity in the vertical profiles of track were taken as a connection between the two models.The results of investigation show that,track settlement accumulates gradually with an increase in action times of dynamic loads on tracks,the initial track irregularity has a strong impact on track settlement,and the wheel-rail forces and track responses increase with the increase in accumulated settlements.
