建立了铁道车辆1:8比例的半车四自由度横向主动悬挂试验模型,应用LQR控制方法进行了主动悬挂与被动悬挂的试验对比研究,并与仿真计算结果进行比较.研究结果表明,主动悬挂方式能有效衰减振动,尤其是共振点处的振动;主动悬挂与被动悬挂相比,车体横移振幅在高频共振点附近平均降低80％左右,在其余频段平均降低约30％;车体侧滚角振幅在高频共振点附近平均降低65％左右,在其余频段平均降低约20％.“,”A one eighth scale half vehicle lateral active suspension experimental model with four degrees of freedom is established. The active suspension and passive suspension experiments are comparatively studied with LQR control law, and the experimental results is comparied with the simulation results. It is shown that the active suspension can effectively attenuate vibration, especially the vibration at the resonant frequency. Compared with the passive suspension, the amplitudes of the lateral and roll vibratio...
