A mass block bow-shaped clamping device for rail vibration reduction

Abstract

The invention discloses a bow-shaped mass block clamping device for rail vibration reduction. The bow-shaped mass block clamping device comprises screwing structures, clamps, novel leaf springs, elastomer-steel member assemblies, supports and elastomers wrapping a rail, wherein the screwing structures, the clamps, the novel leaf springs, the elastomer-steel member assemblies, the supports and theelastomers are arranged on the first side and the second side of the rail. The elastomers are attached to the rail to absorb rail vibration energy, so that overall vibration and vibration in the two side directions of the rail are retarded, the vibration impact of a train on the rail is retarded, the pressures between the screwing structures and the leaf springs are adjusted through rotation and vertical movements of the screwing structures relative to the stainless steel clamps, the elastomer-steel member assemblies increase structural damp of the rail and adjust the vibration frequency of the rail to be close to the frequency of a main structure, and the resonance characteristic of the structure is changed, so that the vibration reduction effect is achieved. The bow-shaped mass block 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 invention relates to the technical field of vibration and noise reduction devices, in particular to a mass block bow-shaped clamping device for rail vibration reduction. Background technique [0002] Since the development of railway transportation, the contact movement of wheels and rails 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 longe...

[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.
