Description
Technical field
The invention belongs to train wheel noise reduction technology field, is damped more particularly to a kind of particle for wheel
Device.
Background technology
China possesses the railway operating kilometrage for occupying the second in the world and the high high-speed railway total kilometrage to rank first in the world at present.
High-speed railway while the mankind be provided going on a journey convenient succinct, but also in the process of running constantly to the straight rolling of ambient radiation and
Other great harm such as bend whistler, windage noise and the noise of penetration capacity, have seriously affected Along Railway residence
The normal life of the people and animal and body and physiological health.And the remote mileage of high ferro and straight running route cause rolling to make an uproar
Sound becomes its main harm noise, and focuses primarily upon 500~5000Hz.
The content of the invention
The present invention proposes that one kind is used for car to solve the vibration noise technical problem in high speed train wheel operational process
The granule damper of wheel.
The purpose of the present invention is achieved through the following technical solutions：A kind of granule damper for wheel, the particle resistance
Buddhist nun's device includes dampener body 2, connecting plate 3 and damping particles 5；The dampener body 2 is solid by welding manner and connecting plate 3
Connect together, the dampener body 2 is a cavity, and the damping particles 5 are filled in the cavity；3 both ends of connecting plate
It is connected with wheel 6 by bolt, is bolted in the middle part of the granule damper on wheel 6.
Further, 2 cross section of dampener body is rectangle, its width matches with the plane on 6 wheel rim of wheel.
Further, the granule damper is installed in the dovetail groove 7 on 6 wheel rim of wheel, being installed on wheel 6
Grain damper quantity is even number, and is uniformly distributed along 6 circumferencial direction of wheel.
Further, the material of the connecting plate 3 is metal, and 5 material of damping particles is metal or nonmetallic, installation
The granular mass of filling is identical inside each granule damper on wheel 6.
Brief description of the drawings
Fig. 1 is granule damper profile of the present invention；
Fig. 2 is granule damper installation partial schematic diagram of the present invention；
Fig. 3 is granule damper integral installation schematic diagram of the present invention.
Embodiment
The technical solution in the embodiment of the present invention is carried out below in conjunction with the attached drawing in the embodiment of the present invention clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, belongs to the scope of protection of the invention.
With reference to Fig. 1-Fig. 3, the present invention proposes a kind of granule damper for wheel, and the granule damper includes damping
Device main body 2, connecting plate 3 and damping particles 5；The dampener body 2 is fixed together by welding manner and connecting plate 3, institute
It is a cavity to state dampener body 2, fills the damping particles 5 in the cavity, damping particles 5 are filled in certain packing ratio
In the cavity of dampener body 2；It is preferably filled with than for 60%.3 both ends of connecting plate are connected by bolt with wheel 6, described
It is bolted in the middle part of granule damper on wheel 6.
2 cross section of dampener body is rectangle, its width matches with the plane on 6 wheel rim of wheel.
The granule damper is installed in the dovetail groove 7 on 6 wheel rim of wheel by bolt, being installed on wheel 6
Grain damper quantity is even number, and is uniformly distributed along 6 circumferencial direction of wheel, to ensure the dynamic balancing in vehicle operation.Phase
Adjacent its connecting plate edge of two dampers shares a fastening bolt, to ensure that damper will not vibration.
The material of the connecting plate 3 is metal, and 5 material of damping particles is metal or nonmetallic, is installed on wheel 6
Each granule damper inside filling granular mass it is identical, to ensure the dynamic balancing in train travelling process.
Both at home and abroad generally wheel is reduced using measures such as bump leveller, damping ring, sound barrier, damping wheel and elastic wheels
Radiated noise, but it is respectively provided with certain limitation and expensive.And granule damper is since it is with superior vibration damping
Performance has been widely used for the fields such as aerospace and industrial production, but is not applied to subtracting for high ferro wheel so far
Shake noise reduction, thus the present invention reduces the vibration noise of wheel by granule damper.In train travelling process, damping is filled in
Friction, collision etc. occur between particle inside device and between particle and damper, so that the vibrational energy of wheel is consumed, from
And achieve the purpose that vibration and noise reducing.Damping particles can be metal, its environmental suitability is preferable.
The present invention solves the unsteadiness of wheels noise problem in high ferro operational process.Granule damper is to develop in recent years
A kind of new noise reduction technology come, has broad application prospects.It can cause during unsteadiness of wheels in damper
The vibration of portion's particle, friction, collision and deformation etc. constantly occurs in particle vibration processes, such unsteadiness of wheels energy just turns
Turn to the kinetic energy and thermal energy of particle.Simultaneously as the deformation of wheel, can occur microcosmic between the connecting plate 3 and wheel 6 of damper
Relative motion, produce the effect of frictional damping, reduce further the vibration noise of wheel.
Granule damper good environmental adaptability, can well adapt to the huge environment difference of China's different geographical.While
Grain damperparameters designability is strong, easy to adjust, can adapt to different classes of wheel.Simultaneously because granule damper is point
Cloth designs, easy for assemble or unload, enormously simplify mounting process and Measuring error time, has preferable practical value and can
Operability.
Granule damper is simple in structure, it forms raw material and is readily available, and cheap, and damper production process is not
Special Working Technology is needed, is easy to mass produce and can be good at control cost.With good economy.
Above to a kind of granule damper for wheel provided by the present invention, it is described in detail, herein should
The principle of the present invention and embodiment are set forth with specific case, the explanation of above example is only intended to help to manage
Solve the method and its core concept of the present invention；Meanwhile for those of ordinary skill in the art, according to the thought of the present invention,
There will be changes in embodiment and application range, in conclusion this specification content should not be construed as to this hair
Bright limitation.
