Description
Technical field
The utility model relates to a kind of foam metal material sound eliminating tile, and the sound eliminating tile of especially processing with foam metal material and neoprene belongs to the noise elimination technique field.
Background technology
When underwater moving body moves under water, because the double vibrations and the liquid motion of the rotation that spiral falls, machinery tend to produce stronger radiated noise.If the radiated noise level of underwater moving body is higher, be easy to detected by unfriendly target, be unfavorable for one's own side's disguise and safety.The self noise of underwater moving body itself is too high, also can have a strong impact on the detection ranging coverage of self sonar.
Be to solve the noise elimination problem of underwater moving body, common way be exactly under water the movable body surface lay sound eliminating tile.Sound eliminating tile is a kind of a kind of measure fairly obvious to the underwater moving body noise reduction, also is the most effective present a kind of method that reduces submarine noise, and novel conventional submarine and atomic submarine that various countries are equipped have all adopted this noise reduction means basically.
The principle of noise reduction of sound eliminating tile; Be to produce impedance match between movable body and the seawater under water, sound wave can be imported in the sound eliminating tile, the effect of shock damping action and watt internal cavity or weighting material through the sound eliminating tile material; Make the waveform generation conversion of sound wave, thereby sound wave is weakened or be absorbed fully.Present sound eliminating tile technology; Also there are many deficiencies aspect radiated noise that reduces underwater moving body and the self noise; As; The effect that suppresses underwater moving body self vibration and the noise radiation of isolation movable body inner machine is not ideal enough, and as broad as long to the absorption usefulness of high frequency sound wave or low-frequency sound wave, aural detector working environment and detection range need be improved.
Summary of the invention
The purpose of the utility model provides a kind of foam metal material sound eliminating tile; Be used for underwater moving body; Utilize the characteristic of foam metal material; Suppress the vibration that underwater moving body self produces, isolate underwater moving body inner machine noise, improve the service conditions and the detection range of underwater moving body sonar to the underwater moving body radiation.
Technical scheme of the present invention is: the foam metal material sound eliminating tile comprises foam metal sheet 4 with certain radian and thickness and its sulfuration is encapsulated as an integrally-built synthetic rubber layer 3.
Said foam metal sheet 4 is for having the schistose texture of certain radian, and its radian is consistent with the surperficial radian of underwater moving body 1, synthetic rubber layer 3 and foam metal sheet 4 radian that is consistent.
The pore-solids ratio of said foam metal sheet 4 is 86～92%, thickness is 6～40mm.
Said neoprene lamella 3 is the rubber layers with irregular holes.
Said synthetic rubber layer 3 outside faces also are coated with solid neoprene outer 5 (can through bonding or press to melt and wait common mode to realize), and synthetic rubber layer 3 is 6～10:1 with the thickness ratio of neoprene skin 4.
The integral thickness of said sound eliminating tile 2 is 20～60mm, and aspect ratio is 100:90～75.
The foam metal sheet 4 of this sound eliminating tile can adopt regular foam metal material sheet such as aluminium, nickel and alloy thereof, and its pore-solids ratio, thickness, sound eliminating tile integral thickness and aspect ratio thereof are selected in giving scope according to actual needs.Synthetic rubber layer 3 all adopts common tartan to process with neoprene outer 5, and synthetic rubber layer 3 forms (random hole) through the neoprene natural foaming, and conventional sulfuration encapsulation technology is adopted in the sulfuration encapsulation.The radian of foam metal material sheet 4 and whole sound eliminating tile is decided according to underwater moving body surface radian.
The utility model is according to tiny finely porous shock damping action of foam metal material and cavity effect; When the sound wave that sends when active sonar acts on this sound eliminating tile; Because tiny micropore and formed cavity and the set various different sizes of neoprene sheet internal layer and the hole of shape of foam metal material face; Can make the waveform generation conversion of high frequency sound wave and low-frequency sound wave; Thereby sound wave is weakened or be absorbed fully, can significantly reduce the reflection strength of detection side's active sonar sound wave, and then can reduce the ranging coverage of detection side's active sonar; Vibration that underwater moving body self produces and underwater moving body inner machine noise contributions are when this sound eliminating tile, and foam metal material can significantly reduce the radiated noise and the self noise of underwater moving body, and then can reduce the detection range of detection side's passive sonar.
The sound eliminating tile that this foam metal material is processed both can significantly reduce the reflection strength of the sound wave of detection side's active sonar; Reduce the ranging coverage of detection side's active sonar; Also can suppress the vibration that underwater moving body self produces; Isolate underwater moving body inner machine noise to the underwater moving body radiation, significantly reduce the underwater moving body self noise, reach the purpose that reduces detection side's passive sonar ranging coverage.
The beneficial effect of the utility model is:
(1) is the sound eliminating tile outside with the foam metal material, absorbed the sound wave of active sonar, reduce or eliminated the reflection strength of the sound wave of active sonar;
(2) with the set various different sizes of neoprene sheet internal layer and the hole of shape, absorbed the sound wave of active sonar, reduce or eliminated the reflection strength of the sound wave of active sonar;
(3) with the foam metal material be the sound eliminating tile the inside; Set up the reflection strength of the sound wave of further reduction active sonar; Suppress the vibration that underwater moving body self produces; Isolate underwater moving body inner machine noise to the underwater moving body radiation, reduce the new design concept and the design philosophy of underwater moving body self noise;
(4) it is positive buoyancy or neutral buoyancy that the foam metal material after sulfuration encapsulates makes sound eliminating tile, does not increase the total weight of underwater moving body;
(5) design for the underwater moving body of hidden-type, calm type provides foundation.
