Abstract

The invention provides a track vibration damper and a rail transit system and relates to the technical field of track vibration damping. The track vibration damper comprises a vibration direction changing mechanism and a vibration absorber; elastic waves spreading in the up-and-down direction pass through the vibration direction changing mechanism; the vibration direction changing mechanism can change the spreading direction of partial elastic waves to form direction-changed waves; the direction-changed waves are sent out from the side wall of the vibration direction changing mechanism; the vibration absorber is arranged on the side wall; the spreading direction of the other part of elastic waves is not changed so that transmitted waves are formed; transmitted waves are sent out from the bottom of the vibration direction changing mechanism; the rail transit system comprises a track body and the track vibration damper; and the vibration direction changing mechanism of the track vibration damper is connected to the bottom of the track body. The track vibration damper has a better vibration damping effect on the track body.

Description

technical field [0001] The invention relates to the technical field of rail vibration reduction, in particular to a rail vibration absorber and a rail transit system. Background technique [0002] Rail transit is an indispensable mode of transportation for people's lives, such as trains, subways and trams, etc. Among them, trains and subways will generate large vibrations when they are running. In addition to causing large noise pollution, the vibrations It also propagates in the vertical direction in the form of elastic waves, causing damage to nearby residential buildings, schools, hospitals and other buildings, and can make people in the nearby area feel obvious shocks, causing panic. [0003] The vibration reduction methods of the existing rail transit generally include setting a shock absorber under the track, such as setting a steel spring floating plate at the bottom of the track to reduce the vibration of the track. The support of the vehicle above, therefore, the s...
