Multi-mass-sheet two-side clamping device for rail vibration reduction

Abstract

The invention discloses a multi-mass-sheet two-side clamping device for rail vibration reduction. The multi-mass-sheet two-side clamping device comprises elastomers, supports, elastomer-steel member assemblies, pressing plates, first locking pieces, second locking pieces, pressing bars with pressing ends, leaf springs and rail gaskets, wherein the elastomers, supports, the elastomer-steel member assemblies, the pressing plates, the first locking pieces, the second locking pieces and the pressing bars with pressing ends are arranged on the first side and the second side of a rail, and the leafsprings and the rail gaskets are located on the pressing plates and the elastomer-steel member assemblies; the spring gaskets and the elastomer-steel member assemblies are attached to the rail, so that the vibration impact of a train on the rail is retarded; the elastomer-steel member assemblies increase structural damp of the rail and adjust the vibration frequency of the rail to be close to thefrequency of a main structure, and the resonance characteristic of the structure is changed, so that the vibration reduction and noise reduction effects are achieved. The multi-mass-sheet two-side clamping device can greatly reduce the energy transmitted by wheels and the rail, prevents the generation of vibration and noise, greatly prolongs the service life of the wheels and the rail, is beneficial to reduction of the use cost of a railway and noise pollution, is convenient to replace and disassemble, and has a very strong practical value and application prospect.

Description

Technical field [0001] The present invention relates to the technical field of vibration and noise reduction devices, and in particular to a clamping device on both sides of a multi-mass sheet used for rail vibration reduction. Background technique [0002] Since the development of railway transportation, the contact movement of wheels and tracks has been accompanied by the generation of impact energy, so the generated vibration is inevitable, causing environmental pollution and bringing great noise pollution to people's lives. The traditional vibration and noise reduction method is to place rubber pads under the sleepers. However, the vibration and noise reduction effect of the rubber pads is not good, and the life of the rubber pads is relatively short, and replacement is more troublesome. With the continuous development of science and technology , The speed of high-speed rail is getting faster and faster, and the vibration and noise generated by it are getting bigger and bigge...

[0002] Since the development of railway transportation, the contact movement of wheels and tracks has been accompanied by the generation of impact energy, and the resulting vibration is inevitable, causing environmental pollution and bringing great noise pollution to people's lives.

The traditional vibration and noise reduction method is to place the rubber pad under the sleeper, but the vibration and noise reduction effect of the rubber pad is not good, and the life of the rubber pad is relatively short, so it is more troublesome to replace. With the continuous development of science and technology , the speed of high-speed rail is getting faster and faster, and the vibration and noise generated by it are getting bigger and bigger. The rubber pad can no longer meet the current vibration reduction requirements.
