Vacuum pipeline magnetic levitation train braking system and method

Abstract

The invention discloses a vacuum pipeline magnetic levitation train braking system and method. Inflation ports are arranged on a vacuum pipeline at intervals. When the pressure inside the pipeline reaches the atmospheric pressure is detected, the inflation ports are closed and the inflation is stopped; and brake wing plates are arranged at the top portions of train compartments, and the opening and closing of the brake wing plates are in cooperation with the opening and closing of the inflation ports for control. When a train sends an emergency braking signal, an air compressor inflate the pipeline through the inflation ports, meanwhile the brake wing plates at the top portions of the train are quickly opened, the air resistance is increased when the train moves, and the train deceleratesto achieve the braking purpose. The vacuum pipeline magnetic levitation train braking system has simple structure, safety and reliability. The emergency braking problem of the vacuum pipeline magneticlevitation train is solved, and stable, safe and effective braking of the train in a vacuum environment and without train wheels is ensured.

Description

technical field [0001] The invention belongs to the technical field of braking of railway vehicles, and relates to a braking system and a braking method for a vacuum pipeline magnetic levitation train. Background technique [0002] As the speed increase of trains in the atmospheric environment is facing more and more problems, energy consumption is increasing, the benefits of speed increase are getting smaller and smaller, and the challenges of operation safety are getting bigger and bigger, which forces people to rethink The future of high-speed trains. American science and technology madman Musk proposed the concept of a vacuum tube capsule super train. The theoretical speed can reach more than 6,000 kilometers per hour. It only takes about 2 hours from Beijing to New York. However, the high-speed operation of the train will bring another problem, which is the speed of the train in a vacuum environment. Braking problem. [0003] The maglev train is a new type of transpor...

AI Technical Summary

Problems solved by technology

Judging from the current braking methods, except for regenerative braking (excluding resistance braking), other braking methods realize braking by converting the kinetic energy of the train into heat energy and dissipating it into the air. In the environment, since the heat generated during the braking process cannot be dissipated, it will cause the temperature of the brake device to rise and reduce the braking efficiency, and even cause the brake device to fail

[0005] Especially when the train needs emergency braking, normal braking measures alone cannot achieve the desired effect
