摘要：地铁牵引电机动态载荷是影响地铁安全运行的重要因素，但现实生活中难以对其准确测量。本课题通过收集文献资料发现地铁牵引电机悬挂方式对电机承受的动态载荷影响较大，进而对三种电机悬挂方式进行对比分析，这三种电机悬挂分别是轴悬式、架悬式和体悬式，最后整理出理论上的结论。利用多体动力学建模软件ADAMS-Rail，建立三种电机悬挂方式的A型地铁模型。仿真时，对三个模型设置相同的轨道参数、外部激励和运行时间，保证所有仿真变量完全一致，对比分析得出仿真结果。经过仿真结果与理论结论的比对研究，确定仿真结果较于实际情况有一定的准确性，验证了运用仿真技术来预测电机动态载荷的可行性。80894

Dynamic Load Forecasting Technology for Subway Traction Motor

Abstract：Subway traction motor dynamic load is an important factor affecting the safety of the subway, but in real environment it is difficult to accurately measure it。 In this paper, it is found that the traction motor of the subway traction motor has a great influence on the dynamic load of the motor, and then the three kinds of motor suspension modes are compared and analyzed。 The three kinds of motor suspension are axle-suspension, semi-suspension, and full-suspension。 Finally, we sort out the theoretical conclusions。 Using the multi-body dynamics modeling software ADAMS-Rail, three types of subway models of motor suspension are established。 In the simulation, the same orbit parameters, external excitation and running time are set for the three models, and all the simulation variables are exactly the same。 The simulation results are obtained by comparison and analysis。 After comparing the simulation results with the theoretical conclusions, it is proved that the simulation results are as accurate as the actual ones。 So the feasibility of using the simulation technology to predict the dynamic load of the motor is verified。
