摘要/Abstract

摘要： 轨道电路是实现轨道车辆占用监测及通信的铁路信号重要组成部分，对行车安全具有十分重要的意义，其中轮轨电阻对轨道电路性能的影响是一个重要的方向。设计一系列基于滚动试验台的轮轨电阻测量实验，通过对行车中多种常见干扰因素如测量参数、轮重、走行速度和轨道状态等进行对比测试，研究其对轮轨电阻的影响。当电压增大、轴重增大、锈蚀越少、车轮踏面粗糙度越高、轮轨间油污减少时，轮轨电阻随之降低，分路效果变好。

Abstract: Track circuit is an important part of railway signal used for monitoring of railway vehicle occupancy and communication, which is of great significance to traffic safety. The influence of wheel-rail resistance on the performance of track circuits is an important direction. In this paper, a series of wheel-rail resistance measurement experiments based on rolling test bench are designed to study the influence of various common interference factors such as measurement parameters, wheel weight, running speed and track state on wheel-rail resistance. When the voltage increases, the axle load increases, the rust is less, the wheel tread roughness is higher, and the oil pollution between the wheel and rail is reduced, the wheel-rail resistance decreases and the shunting effect becomes better.

Key words: track circuit, wheel-rail resistance, equivalent simulation device, effect analysis
