Abstract
The utility model relates to a steel rail dynamic vibration absorber. The steel rail dynamic vibration absorber comprises a rail body (1), a first elastic damping layer (2) and mass blocks, wherein the inner surface of the first elastic damping layer (2) is adhered to the two sides of a web of the rail body (1) and above a rail foot through an adhesive; and the outer surface of the first elastic damping layer (2) is adhered to the mass block through the adhesive. The steel rail dynamic vibration absorber is characterized in that from top to bottom, the mass blocks sequentially comprise a first rigid mass block (31), a second rigid mass block (32) and a third rigid mass block (33) with the masses unequal to one another; and a second elastic damping layer (4) is arranged among the first rigid mass block (31), the second rigid mass block (32) and the third rigid mass block (33). According to the utility model, since the mass blocks are positioned at the two sides of the web of the rail body, the transverse vibration of a rail can be effectively absorbed, further, the torsion vibration is absorbed, and the absorption to the vibration energy of the rail is enhanced in the whole, finally, the noise is better reduced.
Description
Technical field
The utility model relates to a kind of rail dynamic vibration absorber, relate in particular to a kind of to rail laterally with the vertical effective rail dynamic vibration absorber of vibration damping, belong to the track traffic equipment technical field.
Background technology
Vibration that track traffic produces and noise are one of pollution sources of environment to surrounding enviroment influence along the line greatly.At present, the vibration and noise reducing measure of taking is more, and wherein comparatively common method is to adopt sound barrier, but there are some remarkable shortcomings in sound barrier, because the noise diffraction, its effect is limited, and installation cost is high.Measures such as bump leveller, damper are arranged in addition.The patent No. is that 200620049274.0 Chinese patent has been introduced a kind of low noise railway track; Comprise common railway rail and dynamic damper composition, each dynamic damper is made up of two-layer bloom and two-layer elastic damping material layer, and the upper strata is a bloom; It between upper strata bloom and the lower floor's bloom one deck elastic damping material layer; One deck elastic damping material layer is also arranged between the bloom of lower floor and the rail, with the cementing agent gummed, form dynamic damper between bloom and the elastic damping material; Dynamic damper is glued at cementing agent on the foot and web of I shape rail, forms the low noise rail.
The vibration of rail has oscillation crosswise, vertical vibration and three kinds of forms of twisting vibration, and twisting vibration also embodies through oscillation crosswise and vertical vibration.And the vibration position of rail is mainly at the web of the rail and flange of rail place.Above-mentioned patent is owing to have one deck elastic damping material layer between lower floor's bloom and the rail; And there is not the elastic damping material layer between upper strata bloom and the rail; Make this dynamic damper comparatively obvious for the shock attenuation result of vertical vibration; And relatively poor for the shock attenuation result of oscillation crosswise, and twisting vibration also embodies through oscillation crosswise and vertical vibration, so the twisting vibration shock attenuation result is also relatively poor.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of while for horizontal, the vertical and comparatively tangible rail dynamic vibration absorber of twisting vibration shock attenuation result.
The purpose of the utility model is achieved in that a kind of rail dynamic vibration absorber; Comprise track body, first elastic damping layer and the mass; The inner surface of the said first elastic damping layer is pasted on the web both sides and the foot top of track body through cementing agent; The external surface of the said first elastic damping layer is pasted through cementing agent and mass; Said mass comprises the quality unequal first rigid mass piece, the second rigid mass piece and the 3rd rigid mass piece mutually from top to bottom successively; Also be provided with the second elastic damping layer between the said first rigid mass piece, the second rigid mass piece and the 3rd rigid mass piece, also paste continuous between the said first rigid mass piece, the second rigid mass piece, the 3rd rigid mass piece and the second elastic damping layer through cementing agent;
The cross sectional shape of the said first rigid mass piece, the second rigid mass piece and the second elastic damping layer is a rectangle, and said the 3rd rigid mass piece is obedient to the variation of track body cross section profile near the hypotenuse at track body place;
Said first elastic damping layer and mass direction along ng a path are interrupted distribution.
Compared with prior art, the beneficial effect of the utility model is:
The utility model can effectively absorb the oscillation crosswise of track because mass is positioned at the web both sides of track body, thereby has also absorbed twisting vibration, has strengthened the absorption to the track vibration energy on the whole, thereby has reduced noise better.

The specific embodiment
Referring to Fig. 1; A kind of rail dynamic vibration absorber that the utility model relates to; Comprise track body 1, first elastic damping layer 2 and the mass; The inner surface of the said first elastic damping layer 2 is pasted on the web both sides and the foot top of track body 1 through cementing agent; The external surface of the said first elastic damping layer 2 is pasted through cementing agent and mass; Said mass comprises the mutually unequal first rigid mass piece 31 of quality, the second rigid mass piece 32 and the 3rd rigid mass piece 33 from top to bottom successively, also is provided with the second elastic damping layer 4 between the said first rigid mass piece 31, the second rigid mass piece 32 and the 3rd rigid mass piece 33, also pastes through cementing agent between the said first rigid mass piece 31, the second rigid mass piece 32, the 3rd rigid mass piece 33 and the second elastic damping layer 4 to link to each other.The cross sectional shape of the said first rigid mass piece 31, the second rigid mass piece 32 and the second elastic damping layer 4 is a rectangle; Said the 3rd rigid mass piece is obedient to the variation of track body 1 cross section profile near the hypotenuse at track body 1 place, and the said first elastic damping layer 2 is avoided fastener with the mass direction along ng a path and is interrupted installation.
The utility model can effectively be controlled the oscillation crosswise of track because mass is positioned at the web both sides of track body 1, thereby has also controlled twisting vibration, has strengthened the absorption to energy, thereby has reduced noise better.
