Description
Technical field：
The present invention relates to a kind of wheel vibration absorber and wheel noise reduction method.
Background technology：
Wheel-rail noise is one of Main Noise Sources in rolling stock traveling, and there is presently no good means to solve.
In railcar operation, between wheel and wheel track plus lubricant is a kind of method used at present, using gapless rail to subtracting
Few wheel-rail noise also plays a role.In newly-built urban light rail, in some sections, because orbit radius is smaller, wheel with
Between wheel track can due to rub, break away, extrude generation high frequency shriek, so as to bring new traffic noise pollution.
The content of the invention：
It is an object of the invention to provide a kind of wheel vibration absorber and wheel noise reduction method.
Above-mentioned purpose is realized by following technical scheme：
A kind of wheel vibration absorber, its composition include:Installing plate, described installing plate is connected with damping fin, described
Damping fin is connected with liner plate, and described liner plate is connected with back-up ring, and rivet rivets described installing plate, liner plate, back-up ring, damping fin
Together.
Utilize the damping device of described wheel vibration absorber, including 6 to 8 wheel vibration absorbers, described car
Take turns noise reduction damper to be symmetrically and evenly arranged on the wheel rim of wheel with bolt, each described wheel vibration absorber has one group
Intrinsic frequency, and the frequency is consistent with the primary modal frequencies of wheel respectively.
A kind of wheel vibration absorber wheel noise reduction method, including 6 to 8 wheel vibration absorbers, described wheel drop
Damper bolt of making an uproar symmetrically and evenly is arranged on the wheel rim of wheel, and each described wheel vibration absorber is intrinsic with one group
Frequency, and the frequency is consistent with the primary modal frequencies of wheel respectively.
Beneficial effect：
Effectively reduce the wheel-rail noise of wheel in operation 1. of the invention, the frequency band range of noise reduction covering for 800HZ ~
11000HZ.Installing wheel noise reduction damper only increases about 4 kilograms for the weight of each wheel.
The present invention meets the wheel-rim shape of railway car wheel, quick for installation, solid and reliable.
It is of the invention to be uniformly arranged on the wheel rim of wheel to absorb the vibration of wheel, so as to eliminate or suppress wheel and wheel track
Between the noise caused by hitting, slide, rubbing etc..
Brief description of the drawings：
Accompanying drawing 1 is the sectional view of the present invention.In figure, 1 is installing plate, and 2 be liner plate, and 3 be back-up ring, and 4 be damping fin, and 5 be riveting
Nail.
Accompanying drawing 2 is the structural representation of the present invention.
Accompanying drawing 3 is the scheme of installation of the present invention.
Embodiment：
Embodiment 1：
A kind of wheel vibration absorber, its composition include:Installing plate 1, described installing plate is connected with damping fin 4, described
Damping fin be connected with liner plate 2, described liner plate is connected with back-up ring 3, and rivet 5 is by described installing plate, liner plate, back-up ring, damping
Piece is riveted together.
Embodiment 2：
Utilize the damping device of described wheel vibration absorber, including 6 to 8 wheel vibration absorbers, described car
Take turns noise reduction damper to be symmetrically and evenly arranged on the wheel rim of wheel with bolt, each described wheel vibration absorber has one group
Intrinsic frequency, and the frequency is consistent with the primary modal frequencies of wheel respectively.
Embodiment 3：
Above-mentioned wheel noise reduction method, for a discrete single-mode system, when plus one by spring --- matter
After the bump leveller for measuring composition, if the intrinsic frequency of bump leveller is designed to as the intrinsic frequency of former single-mode system,
When original system is with intrinsic frequency exciting, vibration all will be absorbed by bump leveller.After appropriate increase damping in bump leveller, absorbing
The absorbing frequency band of device is broadened, while the vibration of bump leveller also can be consumed quickly.Wheel is hit in operation, rub equal excitation
When, it will radially, laterally producing the vibration of each mode, and outside radiated noise, primary modal vibration frequency 400HZ ~
In the range of 9800HZ；
6 to 8 wheel vibration absorbers are symmetrically and evenly arranged on the wheel rim of wheel with bolt, each wheel noise reduction resistance
Buddhist nun's device contains multiple intrinsic frequencies, and be designed to it is consistent with the primary modal frequencies of wheel, so, when wheel is shaken with modal frequency
When dynamic, can be absorbed by wheel vibration absorber, and by the damping material fast dissipation in wheel vibration absorber, when wheel due to
Long-term use and maintenance diameter becomes hour, and the modal frequency of wheel will be offset, and the damping characteristic in muffler will make its vibration-absorbing denoising
Effect keeps constant.
