摘要/Abstract

摘要： 采用准静态载荷标定的方式制作牵引拉杆载荷传感器，将其安装于某型高速动车组进行线路载荷测试，得到列车启动牵引、高低速直线运行、通过坡道及制动停车等典型工况下的载荷时间历程及载荷变化特点。在此基础上，编制不同速度等级下的牵引拉杆载荷谱，并依据线性累积损伤准则分析结构疲劳损伤分布及运行速度对疲劳损伤的影响规律。研究结果表明，与拖车牵引拉杆载荷相比，动车牵引拉杆载荷幅值变化受电机扭矩载荷的影响较大，尤其在列车启动、制动阶段，其趋势载荷变化明显；随着列车运行速度的增加，牵引拉杆载荷幅值不断增大，得到动车牵引拉杆载荷的振动主频与列车运行速度呈正比。定义相对疲劳损伤来表征每级载荷的疲劳损伤贡献程度，得到结构疲劳损伤与牵引拉杆载荷幅值的对应关系，获取列车运行速度对结构疲劳累积损伤的影响规律。动车牵引拉杆载荷在列车时速280 km/h时产生的结构疲劳累积损伤最小，而拖车牵引拉杆的疲劳累积损伤值随着运行速度的增大呈现增大的趋势。该研究结果对高速列车转向架结构的优化设计及相关理论研究具有一定的参考价值。

Abstract: A load sensor for traction rod is fabricated by quasi-static load calibration method, which is installed on a certain type of high-speed electronic mutil unit(EMU) for line load test. The load time history and load variation characteristics under typical working conditions such as traction during starting, straight line with high and low speed, entry and exit ramp, and braking for stopping are obtained. On this basis, the load spectrum of traction rods at different speed levels are compiled. Based on the linear cumulative damage criterion, the distribution of fatigue damage and the influence of train speed on fatigue damage are analyzed. The results show that, compared with the traction rod load of the trailer bogie, the load amplitude of the traction rod of the motor bogie is greatly affected by the motor torque load, especially in the starting and braking stages of the train, and the trend load changes obviously. With the increase of train speed, the load amplitude of traction rod increases continuously. It is obtained that the main vibration frequency of traction rod load is proportional to the train speed. Relative fatigue damage is defined to represent the contribution of every load grade to fatigue damage. The corresponding relationship between structural fatigue damage and load amplitude of traction rod, and the influence of train speed on cumulative fatigue damage of structure are obtained. The cumulative fatigue damage of the motor bogie traction rod load on structure reaches its smallest value when the train speed is 280 km/h. However, the cumulative fatigue damage value of the trailer bogie traction rod load on structure increases with the train speed. The research results have certain significance for the optimization design of high-speed train bogie and related theoretical research.
