Abstract

The invention provides a vibration damping and sound absorbing assembly for a rail and an assembly system with the same. The vibration damping and sound absorbing assembly for the rail comprises a sound absorbing structure, wherein at least a part of the steel rail is coated with the sound absorbing structure, and the sound absorbing structure is used for absorbing noise generated when a vehicle runs on the steel rail and attenuating vibration generated on the steel rail. The sound absorbing structure comprises a sound absorbing part and a coating part, the surface, facing the steel rail, of the sound absorbing part fits at least a part of the steel rail, and the sound absorbing part is made of foam metal; the coating part is connected with the sound absorbing part and used for coating thesound absorbing part to inhibit vibration of the sound absorbing part and shield noise in order to prevent the noise from radiating outwards. The vibration damping and sound absorbing assembly and the assembly system effectively solve the problem of a poor noise reduction effect on steel rails in rail transit in the prior art.

Description

technical field [0001] The invention relates to the technical field of sound absorption and noise reduction, in particular to a vibration-absorbing and sound-absorbing component for rails and an assembly system with the same. Background technique [0002] At present, the noise problem of high-speed railway and urban rail transit has attracted more and more attention from all parties. How to reduce the environmental noise of railway has always been one of the important tasks of environmental protection workers. In the prior art, damping rails are mainly used for sound absorption and noise reduction, that is, damping and restraint devices are pasted on the rails to reduce the vibration of the rails to reduce noise. [0003] However, the above-mentioned noise reduction methods do not have the function of absorbing and shielding radiation noise, and the effect of sound absorption and noise reduction is not good, causing environmental pollution to residents along the line. Cont...
