摘要随着国内城市轨道交通的大规模建设与陆续开通运营,其安全性日益受到广泛重视。作为城市轨道交通车辆重要组成部件的轮对装置,承受来自车辆的全部静、动载荷,轮对踏面表面和近表面的磨损、擦伤、剥离、裂纹等缺陷是危及行车安全的重大因素,必须及时有效地对车辆轮对尺寸和故障状态进行记录和分析,及时发现轮对缺陷,修复或更换超限轮对,以避免列车事故的发生。本论文在系统分析城市轨道车辆轮对踏面故障的类型、产生原因及其危害的基础上，对车辆轮对管理信息系统功能进行全面分析，重点突出常见故障与测试数据间的关系，轮缘高度超限、轮缘厚度超限、轮径差超限、轮辋宽超限、QR值超限和磨耗率超限等与测试数据间关系，并采用合理的数据分析方法开展上述数据的趋势分析，从而为故障诊断和修复手段提供可靠的技术支持。60932

Title Title Urban rail transit vehicles wheel Management Information System Functional Analysis
Abstract
As the domestic large-scale construction of urban rail transit and opened in succession, its security is becoming more and more widely attention. As an important part of urban rail transit vehicle ,wheel bears all the static, dynamic load from the vehicle, wheel tread surface and near surface of the wear, abrasion, stripping, defects such as cracks are important factors to the safety of driving, must be timely and effectively to wheel size of vehicle state and fault recording and analysis, timely find wheel for defects, repair or replace transfinite wheel on, in order to avoid the happening of the train accident. This thesis on system analysis of wheel tread of urban rail vehicles, the fault types, reasons and its harm, on the basis of the functions of the management information system for vehicle wheel to conduct a comprehensive analysis, highlighting common faults and the relationship between the test data, the out-of-gauge, flange thickness, flange height overrun, wheel diameter difference transfinite, rim width overrun, transfinite QR value transfinite and wear rate. And the test data, relationships between data and adopt reasonable analysis method to carry out the trend of the data analysis, fault diagnosis and repair method for providing reliable technical support.
