Halbach permanent magnet eddy current vibration suppression structure of magnetic levitation turnout

Abstract

The invention discloses a halbach permanent magnet eddy current vibration suppression structure of a magnetic levitation turnout. The structure comprises a turnout main beam, a halbach permanent magnet eddy current damper and a foundation platform; the halbach permanent magnet eddy current damper comprises an induction plate and a bilateral halbach permanent magnet array; the induction plate is installed on the turnout main beam; the bilateral halbach permanent magnet array comprises a first halbach permanent magnet array and a second halbach permanent magnet array which are arranged at an interval; the first halbach permanent magnet array and the second halbach permanent magnet array are installed on the foundation platform; the induction plate is located between the first halbach permanent magnet array and the second halbach permanent magnet array. The halbach permanent magnet eddy current damper is adopted, so that damping force can be increased between the turnout main beam and thefoundation platform, and the vibration of the turnout main beam is restrained.

Description

technical field [0001] The invention relates to a vibration suppressing structure of a magnetic levitation switch, in particular to a halbach permanent magnet electric eddy current structure for suppressing vibration of a magnetic levitation switch. Background technique [0002] The maglev train controls the electromagnet installed on the suspension frame of the train to attract the F rail through the suspension controller, so that the maglev train is in a suspended state, and the linear motor drives the train to run on the track. But the maglev track on the actual line is not absolutely rigid and completely straight. Therefore, the suspension controller needs to adjust the control force through real-time control, so that the train can be suspended on the track at a fixed height, but the continuous adjustment of the control force will cause the vibration of the track structure. In actual operation, due to the existence of structures such as bridges, roadbeds, and turnouts, ...
