摘要
高铁轨道中长波不平顺值是评价轨道几何状态的重要参数,也是指导高速铁路现场轨道精调作业的主要依据,是列车安全高速运行的重要指标之一。本文针对目前高铁轨道矢距差法计算不平顺值,存在计算复杂、计算与检测弦起点的选择有关、结果并不唯一、计算值与实际轨道精调作业调整量方向不一致等问题,提出基于坐标绝对偏差法计算轨道中长波不平顺值的新方法。利用该方法不仅使轨道中长波不平顺值的计算变得简单,而且还与轨道检测弦的起点无关,计算结果唯一,并能满足工程实际需要。
The long-wave irregularity in the high-speed railway orbit is an important parameter to evaluate the geometric state of the track, and it is also the main basis for guiding the fine-tuning of the high-speed rail on-site, It is also one of the important indicators of high-speed train safety. In this paper, according to the problems that the computation of high-speed railway track irregularity calculation is complicated, the choice of calculation and detection string starting point is not unique, the calculation value is inconsistent with the adjustment direction of the actual track fine-tuning operation, and the calculation is based on the coordinate absolute deviation method to calculate the track a new method for long wave irregularity. This method not only makes the calculation of the long-wave irregularity in the track simple, but also has nothing to do with the starting point of the track detection string, the calculation result is unique, and can meet the actual needs of the project.
