Wheel/Rail Contact Irregularity in Crossing Zone of High-Speed Turnout

  • To identify the characteristics of wheel/rail contact irregularity in crossing zone of high-speed turnouts,a numerical model was set up based on the least distance searching method and analyzing the structures of point rail and wing rail. The law of wheel/rail contact irregularity induced by different point hiding structures and wheel treads was investigated by taking a No.42 high-speed turnout for 350 km/h passenger dedicated line as an example.The research results show that the biggest irregularity is located at the gauge measure and wheel/rail contact points transferring from wing rail to point rail.Under the condition of the same point hiding structure and wheel tread,lateral irregularity plays a greater role than vertical irregularity.By adopting a horizontal point hiding structure and respectively reducing the high of point rail by 10.0,3.0 and 0.0 mm in the sections with a top width of 10.0,15.0 or 35.0 mm,wheel/rail contact irregularity can be controlled effectively.Along with the running of trains and the wearing of wheels,lateral irregularity will increase,while vertical irregularity will decrease.
