客运专线列车轮对内侧距选择的研究

首先介绍了国内外关于轮对内侧距对机车车辆动力学性能和轮轨关系影响方面的部分试验研究结果，重点以我国既有线固定辙叉道岔为例，从是否计入测量位置对轮缘厚度的影响，分析不同轮对内侧距通过道岔有害空间的问题，并就轮对内侧距变化后对机车车辆运动稳定性的影响开展滚动台试验研究，对轮对内侧距的影响进行综合分析，为我国客运专线列车轮对内侧距的选择提供参考。

Research on the Selection of the Distance between Backs of the Wheel Flanges of the Passenger Traffic only Line

A part of the test research results about the influence of the distance between backs of the wheel flanges on rolling stock's dynamic performance at home and abroad is introduced first;and then wheelsets of different distances between backs of the wheel flanges pass the gap in the fixed frog switch is analyzed while the variation of the flange thickness corresponding the different measure position was taken into account or not;and the test research about the influence of the distance between backs of the wheel flanges on rolling stock's dynamic performance is done on the rolling rig.The conclusion from the global analysis of above should be a valuable reference to select the distance between backs of the wheel flanges of the passenger traffic only line.
