The two glass layers are arranged unparallel, and the glass close to the noise source is slantingly arranged with an angle of 2-10 degrees with the vertical direction; the glass far from the noise source is installed vertical to the horizontal direction. The sound insulation device is capable of improving the sound insulating and noise reducing capabilities of the door between the noise source machines of the vehicle, thus further reducing the noise in the cab of the vehicle and satisfying the increasing need for comfort by the driver and the passenger.
Description
Technical field
The utility model relates to a kind of sound-insulation noise reducer, is specifically related to a kind of sound-insulation noise reducer for door and window of locomotive.
Background technology
Prior art such as accompanying drawing 1, traditional door and window of locomotive glass sound arrester is by inside and outside two blocks of glass that thickness is 3 ~ 6mm unanimity, and the window door frame between the layer glass and window frame form, and the installation that is parallel to each other of inside and outside two blocks of glass, and the air that is sealed between inside and outside glass and the window door frame becomes a cylindrical body.This kind door and window of locomotive glass sound arrester has reached certain defening effect, but still has certain problem, and is specific as follows described:
1) the glass coincidence effect appears in inside and outside two thickness of glass unanimities easily;
2) air that is sealed between the inside and outside glass of installing that is parallel to each other is a cylindrical body, causes the generation of covibration easily;
3) the window door frame that is installed between the layer glass is a steel plate, influences acoustically effective.
The existing GSC series sound proof window that is used for house ornamentation is made up of with window frame bilayer or triplex glass, and the thickness of glass difference has been controlled " coincidence effect " and the formation low ebb that insulates against sound effectively.Adopt the glass of asymmetric thickness in two glass hollows and three glass hollow glasss, its noise reduction wants big than the noise reduction of the glass of same thickness.Reason is that the acoustic resonance frequency of the glass of different-thickness is positioned at different interval.
During about the design of double-deck sound insulating structure, following theory narrative is arranged in family's acoustic finishing professional knowledge:
A. the resonance frequency of sound insulating structure should design below 50Hz; The thickness of air layer should not be less than 50mm.
B. coincidence frequency should not appear at Mid Frequency.The thickness of each layer of double-decker is unsuitable identical, or adopts different-stiffness, or adds damping.
C. the connection between bilayer should avoid occurring overhead speaker.Double-deck layer with layer between, between double-decker and the basis, should throw off fully each other.
D. should filling porous sound absorption material between double-decker.
Prior art adopts press strip and the press strip core that meets the TB/T1964 standard section, and shown in its weather strip cross sectional shape accompanying drawing 1, its common feature is that the section of connection glass and steel work is a wedge shape.And shown in its weather strip cross sectional shape accompanying drawing 2 of DIN5514-3H, the section that is characterized in connecting glass and steel work is a procheilon structure more than (zigzag structure).This many procheilon structure of theory analysis has better sealing performance.
And in door and window of locomotive, do not adopt the said structure feature.
The utility model content
Defective at present technology existence, the utility model is intended in conjunction with existing sound insulating theory, a kind of sound-insulation noise reducer for door and window of locomotive is provided, can solves following problem from the sealing between sound control glass window glass thickness, the mutual inclination angle of inside and outside glass, interlayer air layer shape, glass and window door frame, the aspects such as surfacing of window door frame:
1) solves the consistent glass coincidence effect that occurs easily of inside and outside two thickness of glass of traditional door and window of locomotive glass sound arrester;
2) solve inside and outside glass the incidental covibration that is parallel to each other is installed;
3) solve press strip and the press strip core existing deficiency in sealing that current employing meets the TB/T1964 standard section;
4) solve window door frame between the layer glass not enough defective that absorbs sound.
Finally can improve the sound insulation and noise reducing ability of door between the machinery of locomotive noise source, thereby reach further reduction locomotive cab,, satisfy the comfort level requirement that the driver and conductor improves day by day promptly away from the noise figure of noise source one side.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sound-insulation noise reducer for door and window of locomotive, the window door frame and the window frame that comprise layer glass and fixing glass, the not parallel installation of described layer glass, become 2 °～10 ° inclination to install with vertical direction by noise source glass, install away from noise source glass is vertical with horizontal direction.
Further, describedly be not less than thickness by noise source glass away from noise source thickness of glass.
Further, be equipped with sound absorption material on the window door frame between the layer glass.
Also comprise preferred version, lean on noise source glass to make and be 5 ° of inclination angles with vertical direction.Between window door frame and glass, adopt rubber press strip and the press strip core that seals, and its cross section meets DIN5514-3 H type cross section.
Basic principle of the present utility model is described in detail as follows:
The inside and outside not parallel installation of glass of a kind of sound-insulation noise reducer for door and window of locomotive that the utility model provides is leaned on noise source glass to make with vertical direction and is certain inclination angle, makes the air layer thickness between two glass inconsistent up and down, is beneficial to eliminate low-frequency resonance; And adopt the thickness that suitably strengthens inside and outside glass, and inside and outside thickness of glass is inconsistent, a little by the thickness of glass relative thin of noise source, thicker relatively away from the thickness of glass of noise source, heavy sheet glass thickness approximately is that the twice that approaches is thick.The influence of glass coincidence effect can be avoided like this, defening effect can be effectively strengthened; On the window door frame between the layer glass, arrange sound absorption material, can further increase sound insulation factor like this, and avoid between the glass, and form overhead speaker between glass and the window frame and influenced defening effect.
And adopt rubber press strip and the press strip core seal between window door frame and glass, and its cross section meets DIN5514-3 H type cross section, the further sealing between reinforcing glass and window frame seals defening effect to strengthen.
In sum, sound-insulation noise reducer for door and window of locomotive described in the utility model has improved the sound insulation and noise reducing ability of door between locomotive machinery, thereby has reached the noise figure of further reduction locomotive cab, satisfies the comfort level requirement that the driver and conductor improves day by day.
