Abstract

The invention provides a medium-low-speed magnetic levitation turnout vibration absorption type main beam structure which aims at solving the coupled vibration problem of an existing medium-low-speed magnetic levitation rail transit vehicle turnout, effectively restraining vehicle turnout coupled vibration and improving the stress condition of the turnout and the vehicle running stability. The medium-low-speed magnetic levitation turnout vibration absorption type main beam structure comprises a turnout wheel disk type steel beam provided with multiple box chambers in the line extending direction and is characterized in that multi-freedom-degree vibration absorption devices are arranged on the turnout wheel disk type steel beam at intervals in the line extending direction, and all the multi-freedom-degree vibration absorption devices are installed in the corresponding box chambers in a suspended manner.

Description

Technical field [0001] The invention relates to rail transit, in particular to a vibration-absorbing main beam structure of a mid- and low-speed maglev switch. Background technique [0002] As a new type of track form, the medium and low speed maglev rail transit has the advantages of safe operation, no pollution and low cost. It has broad application prospects in the development of urban rail transit. [0003] The medium and low-speed maglev train adopts the rail-holding operation mode, and the electromagnet installed on the train suspension frame is controlled by the levitation controller to adsorb the F rail, so that the maglev train is in a suspended state. The linear motor drives the train to run on the track. However, 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 levitate on the track at a fixed height, but the conti...
