Abstract

The invention provides a superconducting magnet connecting device and a superconducting electric magnetic levitation vehicle track system, and the superconducting magnet connecting device comprises a cavity which is disposed on a suspension framework; a heat insulation supporting mechanism which is arranged in a superconducting magnet and is used for connecting and fixing the inner Dewar flask of the superconducting magnet; an elastic supporting mechanism which is arranged in the cavity and used for absorbing first resultant force applied by the suspension framework through the cavity and outputting second resultant force buffered by the first resultant force; a force transfer component which is arranged between the superconducting magnet and the suspension framework; and a plurality of force transmission components which are connected with the heat insulation supporting mechanism and the force transfer component, and are used for dispersedly acting the second resultant force on the heat insulation supporting mechanism so as to dispersedly transmit the second resultant force to the inner Dewar of the superconducting magnet. The force transmission path from the superconducting magnet to the suspension framework is simplified, and the problems that the rigidity requirement of the superconducting magnet is high, the running comfort of a vehicle is low, and the superconducting magnet cannot be stably and safely supported when the vehicle runs at a low speed are solved.

technical field [0001] The invention relates to the field of designing a superconducting electromagnetism levitation running mechanism, and in particular relates to a superconducting magnet connection device and a superconducting electromagnetism suspension vehicle track system. Background technique [0002] The superconducting electric magnetic levitation vehicle (EDS) generally adopts side wall suspension, and the ground suspension guide coil and the ground propulsion coil are arranged on the two side walls of the U-shaped track. The superconducting electromagnets are arranged on both sides of the suspension frame, and the magnetic field generated by the ground propulsion coil It interacts with the superconducting magnet to drive the vehicle, and the magnetic field generated by the superconducting magnet cuts the suspension coil on the ground to form an induced current and an induced electric field, and relies on the interaction between the induced electric field and the su...

Problems solved by technology

[0005] First, the Dewar outside the superconducting magnet suitable for the whole vehicle is generally 5 to 6 meters long, and a series of springs are arranged at the front and rear ends of the top respectively. The load of the whole vehicle is first transmitted to the outer Dewar of the superconducting magnet, and then Inwardly transmitted to the coil of the superconducting magnet, that is, the outer Dewar of the superconducting magnet bears the concentrated load of the whole vehicle; therefore, the strength and stiffness of the outer Dewar are extremely high, resulting in a large mass of the superconducting magnet, which often occupies the entire suspension frame. 50% or more of the mass, and this part of the mass is the unsprung mass, the increase in mass is extremely detrimental to the dynamic performance of the maglev vehicle and the comfort during normal driving

[0006] Second, the superconducting magnet cannot generate sufficient electromagnetic levitation force and guiding force when running at low speed. At this time, the superconducting magnet needs to be safely supported on the suspension frame when it is supported by the landing gear and guide wheels. The first series of springs in the above patent are Air springs, air springs are basically unable to bear the tension, so the first series of springs cannot elastically hang the superconducting magnet, resulting in the inability to support the superconducting magnet stably and safely when the vehicle is running at low speed; in addition, only relying on rigid brakes to support the superconducting magnet at low speed will Causes excessive vibration, resulting in poor comfort when superconducting electric magnetic levitation vehicles run at low speeds
