摘要： 针对转矩波动下电动轮系统机电耦合振动问题,推导了d/q轴坐标系下考虑永磁体磁场谐波的永磁同步电机电磁转矩数学模型以反映轮毂电机转矩波动特征。基于电动轮扭转和纵向耦合振动方程分析了电动轮系统固有特性,考虑电流闭环的影响,并集成转矩模型和振动方程建立了电动轮系统机电耦合模型。基于机电耦合模型分析了耦合对转矩波动和系统振动特性的影响规律,结果表明:电机转子的转速波动在电动轮旋转模态频率处会对电机转矩波动产生负反馈削弱效果;机电耦合主要会改变电动轮耦合系统第三阶模态阻尼比进而影响振动特性,而且阻尼比随磁链的增加而线性增加,随电感的增加而下降直至趋于稳定。因此,合理选取轮毂电机电磁参数对抑制电动轮系统振动有一定的意义。

Abstract: In view of the electromechanical-coupled vibration problem of electric wheel, the electromagnetic torque of permanent magnet synchronous motor is derived in taking account the effects of space harmonics of the permanent magnetic field. Then, based on the equations of coupled torsional and horizontal vibration, the inherent characteristics of the electric wheel system are analyzed. The electromechanical-coupled vibration model of the electric wheel is established by introducing closed-loop control of d/q axis current and combining the electromagnetic torque model and vibration equations. Based on this model the influence rules of electromechanical coupling effects on torque ripple and vibration performance are studied. Results show that the speed fluctuation of the rotor arising from torque ripple will in turn exert an effect of weakening on the torque ripple, especially at the rotating modal resonant operating condition of the electric wheel. The third modal damping ratio of the electric wheel coupling system is evidently influenced by the electromechanical coupling effects and varies with electromagnetic parameters, among which the magnet flux linkage has the largest impact.

Key words: automatic control technology, vehicle engineering, torque ripple, electric wheel system, electromechanical coupled vibration, modal damping ratio
