| 针对SR电机对轮毂驱动电动汽车行驶平顺性的影响，本文首先建立了开关磁阻（SR）电机的转矩波动方程，并根据电机的矢量控制原理，利用Sim Power System Toolbox模块库，搭建了电机模型；然后利用Matlab/Simulink软件，搭建了基于电机模型的机-电耦合振动仿真模型，并进行受轮毂电机转矩波动干扰的车辆垂向动力学模拟仿真。研究结果表明：附加轮毂电机后，车身振动和车轮动载荷都会变大；说明此类汽车工程化应用之前，需要优化悬架，以适应轮毂电机的转矩波动。 |

| In order to study the influence of SR motor on the ride comfort of hub drive electric vehicle, in this paper, firstly, the torque fluctuation equation of switched reluctance (SR) motor is established, and according to the vector control principle of motor, the motor simulation model is built by Sim Power System Toolbox, then using MATLAB/Simulink software, the mechanical-electrical coupling vibration simulation model is built based on the motor model, and the vertical dynamic simulation of the vehicle disturbed by the wheel motor torque fluctuation is carried out. The results show that the vibration of the body and the dynamic load of the wheel will increase after the wheel hub motor is added, which indicates that the suspension needs to be optimized to adapt to the torque fluctuation of the wheel hub motor before the application of this kind of automobile. |
