High-speed dynamic pressure air floatation rail vehicle and rail structure thereof

Abstract

The invention relates to a high-speed dynamic pressure air floating rail vehicle and a rail structure thereof.The high-speed dynamic pressure air floating rail vehicle comprises a vehicle body, the vehicle body comprises a bottom plate, a top plate, a vehicle head plate and two vehicle body side plates, the length of each vehicle body side plate is the same as that of the top plate, and the lower edge of each vehicle body side plate is lower than the bottom plate; a flow limiting plate with the bottom end capable of throttling and swinging is arranged at the tail end of the vehicle body, the lower edge of the flow limiting plate is lower than the bottom plate, the flow limiting plate, the bottom plate and the two vehicle side plates can form a vehicle bottom high-pressure area, and pressure difference can be formed between the vehicle bottom high-pressure area and the upper portion of the top plate. And when the pressure difference is greater than or equal to the gravity of the high-speed dynamic pressure air floating rail vehicle, the high-speed dynamic pressure air floating rail vehicle floats. The air floatation principle and the rail train technology are fully fused, obvious lifting force is generated on the rail vehicle by means of the ground effect, the vehicle is separated from the rail, and the running speed is effectively increased.

Description

Technical field [0001] The invention relates to the technical field of suspended trains, in particular to a high-speed dynamic pressure air-bearing rail vehicle and its rail structure. technical background [0002] Traditional high-speed rail relies on the friction between wheels and tracks, which increases significantly with the increase of vehicle speed. When the vehicle reaches the super-high speed, it will consume a lot of energy to drive the train, and even hinder the further improvement of the train speed. To further improve the running speed of the vehicle, it is necessary to make the wheels of the train in normal running state get out of contact with the track. [0003] Under this background, the maglev train appears, and the suspension of the car body depends on the magnetic force generated by the strong current in the high-temperature superconductor. However, at present, the critical temperature of high-temperature superconducting materials is still low, and the refrige...

Problems solved by technology

However, the structural characteristics of the current ground-effect aircraft are still closer to aircraft, and there are huge wings in its structure, and the wing body cannot be fused, so it cannot be directly applied to trains running at high speed near the ground.
