摘要：
走行系统是影响高速动车组运行安全的关键系统构成，掌握走行系统不同工况下不同部位或设备的振动特性，对实现高速动车组走行系统安全状态检测、健康监测、故障诊断与在线预警具有重要意义。该文基于高速动车组运行实测数据，详细地分析高速动车组车体及转向架多个部件或部位在直线、曲线及道岔通过不同运行工况下振动特性演变规律。首先对数据来源、实验方案及现有高速列车振动特性评价方法进行阐述，进一步分析车体振动特性及转向架多位振动特性，重点涵盖轴箱、构架、齿轮箱和电机关键部件。分析结果对于掌握高速动车组关键设备或部位动态响应及其变化规律具有指导与支撑作用，同时为高速列车关键部件振动性能评价、部件维护检修等提供参考依据。

Abstract: The running system is the most critical influential factor to the operation safety of high-speed train. To grasp vibration characteristics of different parts or equipment under different operating conditions of the running system is of great importance for the realization of the safe condition monitoring, health monitoring, fault diagnosis and online early warning of the running system of high-speed EMU. The vibration characteristics of multiple components or high speed train parts on vehicle-body and bogie were analyzed in straight lines, turns and switches, which were based on the measured data getting from running high speed train in this paper. Firstly, the data source, the experimental scheme and the evaluation method of the vibration characteristics of the high-speed trains were described. Then the vibration characteristics of the vehicle body and the bogie were analyzed, including the axle box, frame, gear box and motor. The analysis results can be used as a reference for mastering the dynamic response of the key parts and the position of the high-speed train and evaluation or maintenance of the key components of high-speed trains.
