Abstract

The invention discloses a suspension bracket device of an electric suspension test bed. The suspension bracket device comprises a suspension tray, a permanent magnet shell, an annular permanent magnet, a balance weight column, a balance weight block, a linear bearing and a guide rod. The annular permanent magnet is packaged in the suspension tray through the permanent magnet shell, the balance weight column is connected to the suspension tray, the balance weight block is installed on the balance weight column, the linear bearing is installed on the suspension tray, and the guide rod is inserted into a bearing hole of the linear bearing and can slide relative to the guide rod; the guide rod is fixed on the test bed through a mounting block at the bottom of the guide rod, the guide rod is inserted through a bearing hole of the linear bearing, the linear bearing can slide relative to the guide rod, the suspension frame performs a suspension experiment of moving in the linear direction through the linear bearing and the guide rod, and when the device is mounted on the horizontal test bed, the suspension tray moves in the vertical direction and suspends. The device can solve the problems that inventions are insufficient in the aspect of permanent magnet electric suspension technology tests and the theoretical research result of the technology cannot be verified, and the popularization of the technology is facilitated.

Description

technical field [0001] The invention relates to the technical field of permanent magnet electric levitation trains, in particular to a levitation bracket device of an electric levitation test bench. Background technique [0002] The maglev train realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and at the same time uses the traction force generated by the traction motor on the train to move forward. The levitation system of the maglev train is the core of the maglev train technology, which is divided into three types: electromagnetic levitation, permanent maglev levitation and electric levitation. [0003] Permanent magnetic electric levitation technology is the product of the combination of permanent magnetic levitation and electric levitation. When the permanent magnet keeps a certain distance on the induction plate and moves at a certain relative speed, an induced eddy current will be generated in the inductio...
