摘要

本文分析了城市(地铁)和干线铁路两种交通系统轨道上检测到的损坏和缺陷的累积情况。总结所进行的分析,应注意的是,图10和图11所示的缺陷在基辅地铁的轨道上更常见。同时,根据图27,在干线铁路运输的轨道上更经常遇到缺陷,也值得注意的是,缺陷范围更广,其比例不超过5%。根据作者的说法,这与运输系统运行条件的特殊性有关,特别是移动设备轴上的负载、移动特性和其他运行参数。为了得出更准确的结论,有必要使用数学建模方法进行大量工作,以考虑单个参数对钢轨缺陷和损伤累积的影响。

Comparative analysis of damages and defects in rails of different railway transport systems
This article provides an analysis of the accumulation of detected damages and defects in the rails of two transportation systems - urban (metro) and mainline railway transport. Summarizing the analysis conducted, it should be noted that defects according to figures 10 and 11 are more often encountered on the tracks of the Kyiv Metro. At the same time, defects according to figure 27 are more often encountered on the tracks of the mainline railway transport, and it is also worth noting a wider range of defects, the share of which does not exceed 5%. According to the authors, this is related to the peculiarities of the conditions for operating transportation systems, particularly the load on the axle of the moving equipment, the movement characteristics, and other operational parameters. In order to make more accurate conclusions, it is necessary to perform a number of works using mathematical modeling methods to take into account the influence of individual parameters on the accumulation of defects and damages in rails.
