摘要

针对电动车存在的动力传动系统扭转振动问题，提出综合考虑控制电机动态特性及传动系统间隙/柔性的机电耦合仿真方法。建立考虑电磁刚度影响的传动系统扭转振动集中质量模型，研究模态特性，并试验验证模型的正确性；考虑齿间侧隙及半轴柔性，搭建传动系统集中-分布质量模型进行动态响应仿真及试验验证；建立、仿真控制电机模型及机电耦合模型，获得转矩波动影响下传动系统扭转振动时频响应。结果表明，所提机电耦合仿真方法能呈现较丰富的动力学现象，有助于进一步揭示电动车传动系统扭转振动特性。

Abstract

Faced on driveline torsion vibration of EV, electromechanical coupling simulation method considering the dynamic characteristics of the control motor and driveline clearance/flexible was proposed. Firstly, driveline lumped mass vibration model was established considering the influence of electromagnetic stiffness, modal characteristics were grasped and verified by test; then lumped-distributed mass model was constructed considering backlash and flexible axle, dynamic response simulation and experimental verification were conducted; finally set up the control motor model and the electromechanical coupling model, driveline torsion vibration response has been obtained under the influence of torque ripple. Results show that the proposed electromechanical coupling simulation method can provide abundant dynamical phenomena, helps to further reveal the driveline torsion vibration characteristic of EV.
