由控制器、横向加速度传感器和半主动减振器等组成的半主动悬挂系统与由风缸、液压缸或电磁铁等促动器组成的主动悬挂系统相比，具有无需外部动力源且不会因控制差错而导致振荡等不安全因素的优点。为了验证半主动减振器的工作性能及其改善高速列车乘坐舒适性的效果，在以300km／h速度运行的500系列动车组上进行了实车试验。结果表明，装用半主动悬挂装置后，车体的横向加速度和横向加速度能量谱都有明显下降，取得了改善乘坐舒适性级2．5dB的效果。
The semi-active suspension system composed of controller, lateral acceleration sensor and semi-active shock absorber, compared with the active suspension system composed of actuator such as cylinder, hydraulic cylinder or electromagnet, has the advantages of no external power source and no Because of control errors and other unsafe factors lead to the advantages of oscillation. In order to verify the performance of the semi-active shock absorber and its effect of improving the ride comfort of high-speed trains, a real vehicle test was carried out on a 500 series EMU operating at a speed of 300 km / h. The results show that the lateral and lateral acceleration energy spectra of the vehicle body obviously decrease after the semi-active suspension device is installed, and the effect of improving the ride comfort level of 2.5 dB has been achieved.
