Compared with the prior art, by using the system of the invention, a rated suspension force is provided by a suspension electromagnet ofa high-temperature superconducting coil part; and a dynamic adjustment suspension force is provided by the suspension electromagnet of a normal conducting coil part so that the maglev train can realize large-air-gap stable suspension, a precision requirement on a track line is reduced, and the system has an important value for increasing the speed of the high-speed maglev train, and particularly has decisive significance for a vacuum pipeline ultrahigh-speed maglev train system.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a hybrid electromagnetic levitation system for high-speed maglev trains. Background technique [0002] The maglev train is a new type of rail transportation with outstanding features such as low operating noise, strong climbing ability, small turning radius, high safety and reliability, low operation and maintenance costs, and low construction cost. It uses electromagnetic suction to suspend the car body above the track, and maintains a non-contact state between the train and the track, which overcomes the contact wear between the two and reduces the running resistance. After decades of technological development, the maglev train technology has basically matured and is gradually moving towards commercial production and operation. [0003] At present, according to the different levitation principles and methods used by maglev vehicles, maglev trains are generally divided into two cat...
