Analysis on Vertical Vibration Negative Influences of In-wheel Motor Electric Vehicle and Shock Absorber Desig

  • 摘要: 针对轮边驱动电动汽车非簧载质量显著增大对车辆乘坐舒适性和操稳性造成的影响,采用功率流方法从能量传递角度进行了分析。仿真结果表明:非簧载质量的增大增加了悬架的能量消耗,影响车辆乘坐舒适性,同时也增加了车轮的能量消耗,影响轮胎接地性能,降低了车辆操稳性。为此,提出了车身型吸振器结构,避免了车轮型吸振器在人体敏感频段容易引发的共振。对吸振器的刚度、阻尼和电机定子质量进行了优化设计,使得车辆垂向振动的能量消耗降低,改善了车辆的乘坐舒适性和操稳性。
