Problems solved by technology

Under high-speed operation, strong aerodynamic lift (the front is usually a negative lift that presses down, and the tail is usually a positive lift that lifts up), making the suspension and control of the train more difficult, and the train is prone to vertical and left-right shaking caused by aerodynamics , reducing the stability and comfort of high-speed maglev train operation
At the same time, since the wheel and rail are not in contact, the brake cannot be braked by friction between the wheel and rail, but can only be braked by the electromagnetic force generated by the linear motor that is opposite to the traction force, and the braking performance needs to be improved.

Description

technical field [0001] The invention relates to a high-speed magnetic levitation train with controllable aerodynamic wings. Background technique [0002] The high-speed maglev train is a new type of rail transportation. Its maglev form can be divided into the normal conduction high-speed maglev mode, which uses electromagnetic force control to realize the levitation in the way of repulsion with the track reaction plate, represented by German TR technology; the low-temperature superconducting maglev mode , use more than 100km / h to cut the magnetic force lines, induce current, form a magnetic field that repels the track reaction plate, and realize levitation, represented by Japan; the high-temperature superconducting maglev train induces current in the magnetic field of the permanent magnet track and forms The magnetic field forms a repulsive levitation force with the magnetic field of the permanent magnet track, as represented by the Chinese "Century". [0003] The magnetic ...
