Study on the Effect of Dynamic Wheel-Rail Contact Geometry Relationship in Turnout Region by the Track-Distance Roughness
Because of the complexity of turnout, the wheel-rail contact of turnout region is more complex than that of railway line. In order to study the wheel-rail contact Geometry relationship of turnout region, using cubic spline interpolation method to get the outline of control sections, the ideal wheel-rail contact relationship in turnout region was obtained by the means of trace line, and then analyze the effect of track-distance roughness on the dynamic wheel-rail Geometry contact, the result shows that appropriate gauge widening can improve the structure irregularity.
