Abstract

The invention discloses a high-speed bullet train with end plates and air brake ground effect wings, and belongs to the technical field of high-speed bullet trains. Ground effect wings are installed on a high-speed bullet train engine and two sides, close to the ground portion, of each compartment in an equal altitude and evenly spaced mode, an end plate is arranged on a wingtip of each ground effect wings, and meanwhile an air brake is arranged on the upper surface of each ground effect wings. The high-speed bullet train with the end plates and the air brake ground effect wings is suitable for a current railway system, abrasion loss between wheel tracks is reduced to some extent, maintenance cost is reduced, and emergency braking distance is shortened effectively. Good air dynamic characteristics are utilized sufficiently, ground effect characteristics of the ground effect wings are enlarged by the end plates additionally, emergency braking is achieved effectively by pneumatic braking, and mechanical wear is reduced greatly. The defects that an existing high-speed bullet train is critical in abrasion between wheel tracks and reconstruction of railway track network of magnetic suspension trains are overcome.

Description

technical field

[0001] The invention belongs to the technical field of high-speed motor vehicles, and in particular relates to a high-speed motor vehicle with an end plate and a deceleration plate ground effect wing. Background technique

[0002] First of all, many technical bottlenecks faced by high-speed EMUs when speeding up have been solved to a certain extent with the continuous improvement of high-performance electric motors, but the costs it brings are also huge, such as severe wheel-rail wear and the resulting High maintenance cost from (see reference [1]: RaghunathanR.S., Kim H.-D., Setoguchi T.Aerodynamics of High-Speed ​​Railway Train[J].Progress inAerospace Science,2002,38:469-514 ). A large number of studies have shown that as the speed of high-speed trains increases, the amount of wheel-rail wear decreases and the contact fatigue intensifies; as the axle load increases, the amount of wheel-rail wear increases rapidly and the contact fatigue weakens; there is a...
