摘要:
［目的］采用钢轨回流的城市轨道交通车辆在运行过程中产生的杂散电流会对附近金属物造成电腐蚀，而专用轨回流方式可解决此类问题。有必要对城市轨道交通车辆回流装置与专用轨的匹配关系进行综合分析。［方法］通过分析城市轨道交通车辆回流装置与专用轨之间的结构匹配特点，基于城市轨道交通车辆转向架、回流装置、走行轨及专用轨等结构的参数，以及悬挂参数和限界，创新性地建立了垂向和横向的尺寸链分析方法，校核了某城市轨道交通在6种工况下车辆回流装置与专用轨的空间尺寸匹配关系。通过SIMPACK仿真软件建立带回流装置车辆整车动力学仿真模型，分析在4种工况下车辆回流装置与专用轨的垂向接触压力在列车运行过程中是否处于合理范围内。［结果及结论］车辆回流装置与专用轨的空间尺寸匹配关系校核表明：回流装置的部分结构需要调整。仿真分析表明：车辆回流装置与专用轨的垂向接触压力均在合理范围内。

［Objective］ The stray current generated during the operation of urban rail transit vehicles with rail backflow method will cause electrical corrosion to nearby metal objects, while the special rail return mode can solve such problems. It is necessary to comprehensively analyze the matching relationship between the backflow device of urban rail transit vehicles and the special rail. ［Method］ Based on the structural parameters of bogies, backflow devices, running rails and special rails of urban rail transit vehicles, as well as their suspension parameters and gauges, a vertical and horizontal dimensional chain analysis method is innovatively established by analyzing the structural matching characteristics between the backflow device and the special rail. The spatial size matching relationship between the vehicle backflow device and the special rail of an urban rail transit vehicle under six working conditions is checked. The vehicle dynamics simulation model with backflow device is established by SIMPACK simulation software. Whether the vertical contact pressure between vehicle backflow device and special rail is within a reasonable range during train operation is analyzed under four working conditions. ［Result & Conclusion］ The checking of the spatial size matching relationship between the vehicle backflow device and the special rail shows that partial structure of the backflow device needs to be adjusted. Simulation analysis verifies that the vertical contact pressure between the vehicle backflow device and the special rail is within a reasonable range.
