The present invention relates to a method for suppressing vibration in a device.

のエネルギーを吸収するものである。It is known that negative damping acts between the superconducting coil of induced repulsion magnetic levitation and the levitation ground coil. In other words, in a system in which only superconducting coils and levitation ground coils are arranged, when vibrations occur, they gradually increase, which is unfavorable in terms of riding comfort.For this reason, conventional methods of passive damping or active damping have been used. Proposed. Passive damping is a method in which a conductive plate is placed between the superconducting coil and the levitation ground coil, and vibration energy is absorbed by the eddy current flowing through the conductive plate as the bogie vibrates.

てしまい、また制御用のコイルを設置する必要があり、
重量が増すという困難があった。Although this method has a simple structure, it is difficult to obtain sufficient force. In addition, active damping involves installing a control coil on the bogie opposite the levitation ground coil, mounting a control device on the vehicle, and applying a current proportional to the speed of vertical vibration to the control coil to apply damping force. It's something you get. In order to obtain sufficient effects with this method, the control device becomes large and it is necessary to install a control coil.
The problem was that the weight increased.

In other words, the present invention does not install any special equipment in the vehicle, but uses induction current collection equipment to collect the AC current. The feature is that sufficient damping force can be generated by the current flowing through the induction current collector coil by controlling the phase of the current.

The figure shows an example of the coil arrangement of a conventional magnetic levitation vehicle. The harmonic magnetic field generated from the levitation coil 3 is used to generate voltage in the induction current collector coil 4, and electric power is transferred to the vehicle. supply to. Figure 2 shows the on-board power system.
The alternating current generated by the induction current collector coil 4 is converted into direct current by the rectifier 5, and power is supplied to the storage battery 6 and the load 7. Figure 3 shows the relationship between the phase angle of the current flowing through the induction current collector coil and the force generated by this coil; when the phase lags, an upward force acts, and when the phase advances, a downward force acts. Furthermore, since the power factor is close to 1 near the zero phase, the condition for collecting a large amount of power is satisfied. FIG. 4 shows the control block of the vibration damping method of the present invention, in which the vibration accelerometer 11
The acceleration of the vertical vibration of the truck is detected by the integrator 1.
2, the speed of vibration is determined, and this is input to the phase angle control section 13, and the phase of the current is changed in proportion to the speed of vibration by a rectifier 14 using a GTO or the like.

。The phase angle control unit 13 advances the phase when the speed of vibration is positive,
Moreover, it works so that the speed and phase angle are proportional. By controlling in this way, for example, when the speed of vibration is upward, the phase of the current advances, so it can be seen that a downward force acts on the induction current collector coil, that is, a force that suppresses vibration acts.
