Description

technical field [0001] The invention relates to a novel high-speed magnetic levitation train structure, in particular to a novel high-speed magnetic levitation train and a levitation mechanism with simple structure and low electromagnetic pollution. Background technique [0002] A maglev train is a train propelled by magnetic levitation force, that is, magnetic attraction and repulsion. Because the magnetic force of its track separates the contact surface between the train and the track and reduces friction, the maglev train has high speed, stable and comfortable operation, easy to realize automatic control, no noise, no harmful exhaust gas, which is beneficial to environmental protection and can be used It has many advantages such as saving construction expenses, low operation, maintenance and energy consumption costs, and it is an ideal super express train in the 21st century. All countries in the world attach great importance to the development of maglev trains. [0003]...

AI Technical Summary

Problems solved by technology

[0003] At present, China, Japan, Germany, Britain, the United States and other countries are actively researching maglev trains. At present, China mainly studies low- and medium-speed maglev trains. The main technology of high-speed maglev trains is in the hands of Japan and Germany, and they are divided into two categories in terms of structure. One is a high-speed constant-conduction maglev train represented by Germany. This type of suspension has a small air gap and a speed of 400-500 kilometers per hour, which is suitable for long-distance rapid transportation between cities. The other is based on The superconducting maglev train represented by Japan has a large air gap, but its speed can reach more than 500 kilometers per hour. The train floats, although the above-mentioned maglev technology has many advantages, there are still some shortcomings, such as: 1. Since the maglev system uses electromagnetic force to complete the suspension, guidance and driving functions, the safety guarantee measures for maglev after power failure, especially for trains The braking problem after a power failure is still a problem to be solved, and its high-speed stability and reliability still need a long time of operation test; The requirements for sinking weight and turnout structure are higher than those of superconducting technology; 3. Superconducting magnetic levitation technology has higher energy consumption than conventional technology due to the eddy current effect, the cooling system is heavy, and the strong magnetic field has an impact on the human body and the environment; 4. Both the normal conduction and superconducting maglev train track lines use electromagnets, which need to rely on electric power during operation, and there are problems such as large power consumption
