Problems solved by technology

[0002] At present, the known means of speeding up trains based on high-speed railways is to use magnetic levitation to reduce the friction of the wheels on the rails. However, the disadvantages of the magnetic levitation method are: 1. The train cannot change tracks, unlike trains that run on conventional railways. Turnouts pass from one rail to another; one track can only accommodate one train running back and forth, resulting in a waste of resources
2. Since the maglev system relies on electromagnetic force for levitation, guidance and driving operation, once the power is cut off, the maglev train will have serious safety accidents, so the safety guarantee measures for the maglev train after the power failure have not been completely resolved
3. Strong magnetic fields will have adverse effects on human health, the balance of the ecological environment and the operation of electronic products

Abstract

The invention relates to a locomotive and coaches in a railway system, in particular to a high speed railway based aerodynamic aerotrain applying aerodynamics and provided with simulated wings. The simulated wings simulating a wing structure of an airplane are mounted on the top portion of each locomotive and each coach of a train. During traveling, due to the simulated wings mounted on the train, airflow moving relative to the train acts on the simulated wings to generate uplifting force, the uplifting force can be applied to the train traveling at high speed, so that pressure on a rail from the train is reduced, and since the force is generated by aerodynamic force, no extra energy is consumed, and no pollution is caused. Via relative motion to the train, the airflow can act on the simulated wings to generate the uplifting force, so that pressure on the rail from the train is reduced. The simulated wings are simple in structure.

Description

technical field [0001] The present invention relates to locomotives and carriages in the railway system, and in particular to the use of aerodynamics to generate a certain degree of air suspension force for high-speed trains through the imitation wing structure imitating the wing structure of an airplane installed on the train An aerodynamic levitation train with imitation wings based on high-speed rail. Background technique [0002] At present, the known means of speeding up trains based on high-speed railways is to use magnetic levitation to reduce the friction of the wheels on the rails. However, the disadvantages of the magnetic levitation method are: 1. The train cannot change tracks, unlike trains that run on conventional railways. Turnouts enter from one rail to another; one track can only accommodate one train to and fro, resulting in a waste of resources. 2. Since the maglev system relies on electromagnetic force for levitation, guidance and driving operation, once...
