干线轨道不平顺紧急补修标准的研究

Reseach on Standards for Emergency Repair of Track Irregularities for Trunk Main Lines

本文通过计算机模拟分析各种轨道不平顺对车辆的动力响应,经过人工设置的各种轨道不平顺对车辆动力影响的轮轨动力学试验,根据我国铁路轨道的实际现状,制订出了高低、轨向、轨距、扭曲、水平等五种轨道不平顺的紧急补修标准值,对于超过紧急补修标准值的不平顺处所,则必须立即整修,及时消除可能危及行车安全的因素。

This paper is intended to describ the computer analysis of the dynamic vehicle response to track irregularities, based on the actual track conditions of existing railways. Through wheel/rail dynamic tests with artificial track irregularities, the standards for urgent repair of track irregularities in terms of profile, a alignment, gauge, twist and crosslevel, have been drawn up. The defects exceeding the standards must be remedied immediately so as to eliminate and factor endangering the safe operation of trains.
