Medium-and low-speed maglev train adopts embraces the rail method of operation, and the electric magnet controlling to be installed on train suspension rack by suspension controller adsorbs F rail, makes magnetic-levitation train be in suspended state. Train is driven to orbit by linear electric motors. But magnetic levitation track is not absolute rigidity and totally straight on actual track. Therefore suspension controller need to adjust control power by controlling in real time so that train can be suspended in fixing height in orbit, but the continuous adjustment controlling power can cause track structure to vibrate. But sub rail foundation kind is many in reality, structure is complicated, not only has bridge, roadbed to also have track switch etc. Under different rails, structure can make track show different vibration characteristics. So that carry out vibration research respectively for different structural vibrations such as track, bridge, track switches, find the measure of low Criterion for Maglev Guideway Structures vibration solving from multiple angles such as suspension controller, structure optimization and structural vibration reductions. Such as Chinese patent CN104389247A vibrates a kind of powered shock absorption device suitable in medium-and low-speed maglev car F rail of proposition power and F rail structure for F rail. But effective solution currently there are no for maglev vehicle-track switch Coupled vibration problem.
Present invention is generally directed to the Coupled vibration problem of medium-and low-speed maglev vehicle and track switch, it is proposed to a solution. Owing to medium-and low-speed maglev track switch adopts steel beam structure, relative to interval orbit beam, deadweight is little, natural frequency of structures is low, structural damping is little for it, suspension controller stability requirement is higher, therefore, when suspension controller adaptive capacity is strong not, vehicle is by Cha Qu and car trouble coupled vibrations easily occurs, and not only to work in forward position additionally, due to track switch, working in lateral position, when working in lateral position, the horizontal vibration of car trouble also can not look down upon simultaneously.
Summary of the invention
The present invention provides a kind of medium-and low-speed maglev track switch absorbing type main beam structure, to solve current medium-and low-speed maglev rail vehicle trouble Coupled vibration problem, effectively suppresses car trouble coupled vibrations, improves track switch stress, improve vehicle smoothness.
This invention address that the technical scheme that technical problem adopts is as follows:
The medium-and low-speed maglev track switch absorbing type main beam structure of the present invention, including the track switch web-type girder steel on circuit bearing of trend with multiple chamber, it is characterized in that: described track switch web-type girder steel interval on circuit bearing of trend arranges multiple degrees of freedom shock-absorbing means, each multiple degrees of freedom shock-absorbing means hangs in the chamber being installed on correspondence.
Described multiple degrees of freedom shock-absorbing means includes installation component, spring damping component and a quality device, mounting seat component includes the upper group of mounting seat at vertical interval, lower group of mounting seat, upper group of mounting seat, lower group of mounting seat respectively include at least three circumferentially spaced mounting seats, mounting seat is fixing with track switch web-type girder steel to be connected, each mounting seat is connected with quality device each through a spring damping component, quality device is hung in chamber.
The invention has the beneficial effects as follows and can effectively suppress car trouble coupled vibrations, the vertical of track switch and horizontal direction are vibrated all significant inhibitory action, and the dynamic stress amplitude reducing track switch girder extends the track switch girder life-span. Powered shock absorption device is arranged in track switch girder, and structure is attractive in appearance.
