摘要
为分析牵引电机振动对高速列车动力车垂向动力学性能的影响,在传统列车-轨道垂向耦合动力学模型基础上,考虑牵引电机与列车之间的耦合运动关系,建立牵引电机不平衡磁拉力、轨道随机不平顺共同作用下的含牵引电机振动的列车-轨道垂向耦合动力学理论模型,并利用实车线路运行试验验证了模型的有效性,在此基础上,分析含牵引电机振动的列车-轨道垂向耦合动力学模型与传统列车-轨道垂向耦合动力学模型垂向随机振动响应之间的差异,并揭示了牵引电机不平衡磁拉力对高速列车车体、转向架构架、轮对,以及牵引电机壳体及其转子垂向动力学特性的影响规律。研究成果为高速列车动力车的垂向振动特性分析及结构参数优化提供了有效的理论分析工具。
In order to analyze the influence of traction motor vibration on the dynamic performance of high-speed train’s power vehicle,based on the traditional train-track vertical coupling dynamic model and considering the coupling motion relationship between the traction motor and the train,a train-track vertical coupling dynamic model with considering traction motor vibration under the combined action of the traction motor unbalanced magnetic pull and track random irregularity is established,and the effectiveness of the model is verified by real vehicle test.Based on this,the difference between the vertical random vibration response of the train-track vertical coupling dynamic model with considering traction motor vibration and the traditional model is analyzed,and the influence of the traction motor unbalanced magnetic pull on the vertical dynamic characteristics of the high-speed train key components and the traction motor is revealed.The research results provide an effective theoretical analysis tool for the vertical vibration characteristic analysis and structural parameter optimization of the high-speed train’s power vehicle.
