Problems solved by technology
[0003] At present, the relevant laboratories have built a rail high-speed train model experiment platform and a maglev train model experiment platform, but the subjects and experimental research in the two fields are irrelevant to each other, and they are even more separated. The advanced technologies in their respective fields are incompatible and cannot achieve complementary advantages.

The invention provides a sub-vacuum maglev supersonic train model experimental platform for additionally arranging an inverted U-shaped excitation cover on the present high-speed rail. The sub-vacuummaglev supersonic train model experimental platform comprises a train model (hereinafter referred to as the train model) shell, wheels, the rail and permanent magnet bar blocks which are installed inthe train model. The externally additionally arranged inverted U-shaped excitation cover (series) is combined with the existing rail road base wall skirt to establish the closed sub-vacuum pipeline, and the train model performs high-speed operation in the pipeline. A pulse current module (series) is connected with inverted U-shaped excitation coils in turn through circuits. The excitation pulse phase sequence and electric energy transmission of a photoelectric detection system, a speed servo control unit and a charging and energy storage device are controlled by a train operation control system so as to change the alternating magnetic field and control the train model to operate in a speed-up or slow-down mode. The train model still depends on magnetic levitation as the power in the speed-up mode to realize frictionless low-air-resistance and supersonic operation; and the train model naturally falls due to gravity in the slow-down mode, the wheels are contacted with the rail and mechanical braking is realized so as to realize stopping or safe parking.
Description
Technical field: [0001] The invention relates to a brand-new supersonic train model experiment platform, especially a sub-vacuum pipeline formed by building roadbed dadoes on both sides of the existing high-speed rail track and installing reverse U-shaped excitation covers, using magnetic levitation as the driving force, and using the track as a safety mechanism. A dynamic supersonic high-speed train model with low air resistance. Background technique: [0002] At present, there are two types of trains whose speed is constantly increasing. One is a high-speed wheel-rail train powered by a high-voltage electric drive motor to allow the wheels to run on the track. The speed can reach 400Km / h, and the braking is stable and safe, but the wheel Sweeping force, especially track contact friction and air resistance will seriously hinder the improvement of its speed; another kind of maglev high-speed train powered by maglev without (track) contact friction, because there is no mechan...
