Research on Vehicle-Coupled-Guideway Vibration in Hybrid Maglev System
The model of vehicle-coupled-guideway vibration in hybrid maglev system with electromagnets and permanents was established at first in this paper, which was based on the calculation of suspension force and dynamical characteristics of guideway. The vibration in hybrid maglev system was discussed by analyzing equivalent block system of the closed loop system. The conclusion was drawn that vehiclecoupled guideway vibration couldnt be restrained when the damping is provided by absolute accelerations integral. Then it was proved that vibration could be restrained by increasing damping which was provided by gaps differential. Because gaps differential couldnt be measured directly, a practical method to obtain it from gap signal was introduced. This method was used in actual control circuit and its validity was proved by experiment. The experimental result also showed that vehicle-coupled-guideway vibration was restrained by increasing the coefficient of gaps differential, and this control method could be applied to hybrid maglev system.
