Abstract
The invention discloses a vibrating table arranged in a damping room, and is characterized by comprising a shock isolation device, wherein the shock isolation device comprises a sound insulation piece arranged between the damping room and the vibrating table. Through setting the shock isolation device, the vibrating table and the damping room are isolated with each other, the background noise of the vibration on the damping room and the harmful effect of a free sound field are reduced furthest.
Description
Technical field
The present invention relates to a kind of shaking table that is installed in the anechoic room.
Background technology
In the acoustical testing process; Sometimes need test products under shock conditions, to test; Therefore need in (following is example with the anechoic room) test environments such as anechoic room, sound reducing enclosure or quiet room, place shaking table, carry out acoustical testing on the shaking table and test products is placed on.
With reference to Fig. 2, in the prior art, shaking table 20 normally directly is placed on the inside of anechoic room 22 so that test products (figure does not show) is carried out acoustical testing; But because shaking table 20 itself can produce vibrations, these vibrations are passed on this body structure of anechoic room 22 easily so, can cause the background noise of anechoic room 22 and the deterioration of free found field.
Summary of the invention
The objective of the invention is to above-mentioned defective of the prior art, a kind of shaking table that is installed in the anechoic room is provided, it can reduce the harmful effect of its vibrations to the structure of anechoic room own to greatest extent.
For realizing the foregoing invention purpose; The present invention has adopted following technical scheme: a kind of shaking table that is installed in the anechoic room; It is characterized in that it is provided with the vibration isolation device, said vibration isolation device comprises the sound insulating member that is arranged between said anechoic room and the said shaking table.
In addition, the present invention also proposes following attached technical scheme:
Said shaking table comprises the bottom of main part and supportive body portion.
Said vibration isolation device also comprises the beam of the lower surface that is arranged on the shaking table bottom.
Said sound insulating member is processed by soft sound-proof material.
Said sound insulating member is arranged on the both sides of the bottom of shaking table.
Said anechoic room comprises base plate, and said base plate is provided with breach, and the bottom of said shaking table is installed in the said breach.
Said vibration isolation device also comprises rubber strip, and said rubber strip surrounds the bottom of said shaking table.
Than prior art, the invention has the advantages that: shaking table is through being provided with the vibration isolation device, makes to isolate each other between itself and the anechoic room and can reduce its vibrations to greatest extent to the background noise of anechoic room and the harmful effect of free found field.
Description of drawings
Fig. 1 is installed on the section plan in the anechoic room for the shaking table corresponding to preferred embodiment of the present invention.
Fig. 2 is installed on the section plan in the anechoic room for shaking table of the prior art.
Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical scheme of the present invention is done further nonrestrictive detailed description.
With reference to Fig. 1, a kind of shaking table 3 in the anechoic room 1 that is installed on corresponding to preferred embodiment of the present invention, it is provided with vibration isolation device 5, so that reduce the harmful effect of its vibrations to 1 body structure of anechoic room to greatest extent.
This anechoic room 1 is also replaceable to be other acoustical testing environment such as sound reducing enclosure or quiet room, a plurality of beams 14 that it comprises base plate 12 and is installed in base plate 12 belows.The centre of base plate 12 is provided with breach 16.
Above-mentioned shaking table 3 comprises the bottom 34 of main part 32 and supportive body portion 32.Be used to place tested product (figure does not show) on the main part 32.Bottom 34 places in the above-mentioned breach 16.
Said vibration isolation device 5 comprises the sound insulating member 52 that is arranged between said anechoic room 1 and the said shaking table 3; Particularly; This sound insulating member 52 is installed in the both sides of the bottom 34 of shaking table 3, and is processed by soft sound-proof material, makes shaking table 3 and anechoic room 1 isolate each other but not directly contact.This vibration isolation device 5 also comprises beam 54 and rubber strip 56.Beam 54 is arranged on the lower surface 35 of the bottom 34 of shaking table 3; And said rubber strip 56 surrounds the bottom 34 of said shaking table 3, so that the isolating exterior noise is to the influence of shaking table 3.
It is thus clear that; Of the present inventionly be installed on shaking table 3 in the anechoic room 1 through vibration isolation device 5 is set; Make and isolate each other through sound-proof material between itself and the anechoic room 1; Thereby can reduce the harmful effect of its vibrations to greatest extent, and ability while isolating exterior noise is to the harmful effect of shaking table 3 to 1 body structure of anechoic room.
It is pointed out that above-mentioned preferred embodiment is merely explanation technical conceive of the present invention and characteristics, its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
