Eddy current resistance reducing technology capable of being used outside high speed train

Abstract

An eddy current resistance reducing technology capable of being used outside a high speed train is characterized in that a resistance reducing device front air inlet (3) is formed in a conical tip body part at the forefront of a resistance reducing device housing layer (1); an annular gas outward moving gap (2) is formed in the rear part of the air inlet (3) and in the part, having a very small distance from the air inlet, on the external surface of the peripheral part of the resistance reducing device housing layer (1); a bottom resistance reducing depression (7) with a larger backward concave depth is made on the external surface of the front part of a movable air sealing device (6) which is made at the rear part of an internal side air moving space (12) on the internal side of the resistance reducing device housing layer (1); and a hydraulic control device (9) capable of controlling the movable air sealing device (6) arranged at the tail part of the internal side air moving space (12) on the internal side of the resistance reducing device to move forwards and backwartds in a reversible manner according to needs is also arranged in an eddy current resistance reducing device whichis made at the front part of the train and has the air inlet and the annular air outward moving gap.

Description

Technical field: [0001] The invention relates to a drag reduction technology that can be applied on the outer surfaces of high-speed trains, bullet trains, automobiles and other high-speed trains. Background technique: [0002] Present high-speed trains, bullet trains, automobiles, and other high-speed trains need to reduce drag during motion. And the outer surface of the compartment behind the front of the car is made into a nearly flat shape to achieve. However, although the application of this technology can achieve a certain degree of drag reduction, after long-term repeated application and technical development on the upper part of high-speed rail trains, it has basically matured and finalized, and there is little room for further substantial improvement. For the resistance of high-speed trains such as high-speed trains in motion, it is necessary to consider finding more effective drag reduction mechanisms for other bluff body shapes.
