Abstract

The invention discloses a high-speed train anti-vibration and noise reduction structure, which comprises a transmission shaft and a noise reduction mechanism, wheels are connected to the outer sides of the two ends of the transmission shaft correspondingly, a first anti-vibration mechanism is arranged in the middle of the transmission shaft, second anti-vibration mechanisms are arranged at the twoends of the transmission shaft, the first anti-vibration mechanism is composed of a fixing seat, a first mounting seat, a first supporting rod and a first return spring, and fixing grooves are formedin the two ends of the top of the fixing seat correspondingly. According to the high-speed train anti-vibration and noise reduction structure, the gas flow in a gas supply pipeline is controlled through a flow controller, gas is ejected on the suction side of a cavity of a train by an ejector, thus a cutting layer on the upper part of the cavity is affected, collision between the cutting layer and the back wall of the cavity is reduced, thus the aerodynamic noise in the cavity is decreased, and the purpose of noise reduction is achieved.

Description

technical field [0001] The invention belongs to the related technical field of anti-vibration and noise reduction of trains, and in particular relates to an anti-vibration and noise reduction structure of a high-speed train. Background technique [0002] High-speed trains, also known as high-speed trains, refer to trains that can run continuously at high speeds, and the maximum speed generally reaches more than 200km / h. With the development of technology, the speed of high-speed trains put into operation can reach 350km / h. On January 17, 2014, during the Qingdao Pure Test "South Railway Test", the speed of the high-speed train was as high as "605 km / h". [0003] When a high-speed train is running, the collision between the wheels and the rails and the wind noise of the train cannot be avoided, which will affect the overall vibration and noise of the train. Therefore, anti-vibration and noise reduction measures for high-speed trains are essential. In the prior art, the comm...
