Abstract

The invention discloses a detection method, device and readable storage medium of a track noise source, and relates to the technical field of signal processing. A method for detecting a track noise source includes: predicting wheel-rail noise and bridge structure noise for an elevated track section to be detected, and obtaining vibration response information of wheels corresponding to the elevated track section to be detected, vibration response information of rails, and bridge structure information. Vibration response information: based on the vibration response information of the wheel, the vibration response information of the rail and the vibration response information of the bridge structure, the noise contour of the elevated track section to be detected is obtained. After obtaining the noise contour of the elevated track section to be detected, the main distribution of the wheel-rail noise source and the bridge structure noise source of the elevated track section to be detected can be determined according to the noise contour, and then corresponding measures can be taken according to the noise source. vibration and noise reduction measures.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a detection method, device and readable storage medium of a track noise source. Background technique [0002] With the development of urban rail transit, due to the construction of elevated rail routes around residential areas and office areas, when trains run on elevated rail routes, noise will be generated to affect surrounding users. Noise sources need to be identified for elevated track routes in order to reduce noise. At present, the identification method of the noise source of the elevated track route is to judge the frequency domain distribution of the noise through spectrum analysis, thereby inferring the noise source of the elevated track route indirectly. Therefore, the noise source of the elevated track route inferred by the indirect guessing method may deviate from the actual elevated track route. Contents of the invention [0003] The present ap...
