摘要: 为某商用车增程器建立了包括发动机、离合器、扭转减振器、发电机和增程器控制系统在内的增程器扭转振动模型,重点分析了典型工况下系统的响应状态、激励转矩和扭转振动的时域和频域特性。结果表明,增程器的扭转振动主要与发动机和发电机激励转矩波动与突变,以及部分工况下的共振有关。

Abstract: A torsional vibration model consisting of the models of engine, clutch, torsional damper, generator and range extender controller is established for the range extender of a commercial vehicle, and the response states of system, excitation torque and the time-domain and frequency-domain characteristics of torsional vibration under typical conditions are emphatically analysed. The results show that the torsional vibration of range extender is mainly related to the fluctuation and abrupt change of excitation torque of engine and generator and the resonance in some conditions
