Abstract
The utility model provides a kind of naval vessel kuppe entrant sound window construction, and main body is Composite Sandwich structure, comprising wainscot 1, outer panels 3 and sandwich 2, panel material is fiberglass, belong to galss fiber reinforced resin based composites, core is foamed material, panel and core close adhesion.Sound transmitting window sound translative performance of the present utility model is good, and foam core characteristic impedance is close with seawater acoustic characteristic impedance.The utility model considers requirement of the structure in terms of intensity with acoustic characteristic, and which had excellent sound translative performance after structural strength is met, both, and the flow noise produced during also suitably reducing shipping agency is disturbed to the signal of sonar array.
Description
Technical field
The utility model is related to a kind of naval vessel kuppe entrant sound window construction.
Background technology
Modern large and medium-sized surface ship ship bow bottom is configured with the comprehensive sonar array of bow detection mostly, in order to avoid current
Impact to sonar array, makes basic matrix from the direct interference of " pseudo- sound ", generally configures kuppe outside sonar array.It is equipped with
The naval vessels bulb bow kuppe of sonar is the detection window of anti-submarine warfare under water.As the operating cabin of equipment, naval vessels bulb bow
Kuppe sound transmitting window structural requirement have good acoustical behavior, less wave beam distortion, good hydrodynamic performance and
Relatively low self noise.Therefore the acoustics design of the material of sonar dome, line style and structure will ensureing hull lines, to meet structure strong
On the premise of degree, good acoustical behavior is realized, complete the major function that excellent service is provided for sonar.
Sonar dome needs acoustic window material.Earliest sonar dome is to adopt stainless steel material, and coverboard sheet metal is reduced
The sound transparency of kuppe, in order to improve the sound translative performance of coverboard material, on the basis of steel material, has developed titanium alloy, steel wire
Net strengthens the coverboard materials such as rubber, fiberglass (GFRP), fiberglass-rubber composite.Said structure form is in some aspects
Performance project, but its combination property is also preferable not to the utmost.Thus the utility model proposes a kind of new kuppe entrant sound window construction
Form, the utility model are fiberglass-foam sandwich construction, and high comprehensive performance can promote the use of.
Content of the invention
The purpose of this utility model is to provide for a kind of new type of ship kuppe entrant sound window construction of high comprehensive performance,
The requirement of mechanics, acoustics and the noise reduction of kuppe is comprehensively met.
The purpose of this utility model is realized in：Including three layers be made up of wainscot, middle sandwich and outer panels
Bonded to each other between structure, and wainscot, middle sandwich and outer panels.
The utility model also includes some architectural features such：
1. the material of wainscot and outer panels is fiberglass.
2. middle sandwich is foamed material.
Compared with prior art, the beneficial effects of the utility model are：This kind of kuppe sound transmitting window version is comprehensively examined
Consider requirement of the structure in terms of intensity with acoustic characteristic, which had excellent sound translative performance after structural strength is met, both, also
The flow noise produced during suitably reducing shipping agency is disturbed to the signal of sonar array.Namely sound transmitting window of the present utility model is saturating
Acoustic performance is good, and foam core characteristic impedance is close with seawater acoustic characteristic impedance.
Description of the drawings
Fig. 1 is kuppe sound transmitting window version schematic diagram of the present utility model；
Fig. 2 is the enlarged diagram of the kuppe in Fig. 1.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
In conjunction with Fig. 1, the utility model main body is Composite Sandwich structure, comprising wainscot 1, outer panels 3 and sandwich 2,
Panel material is fiberglass, belongs to galss fiber reinforced resin based composites, and core is foamed material, and panel is tight with core
Bonding.The sound transmitting window sound translative performance of this version is good, and foam core characteristic impedance is close with seawater acoustic characteristic impedance.This reality
Good with new sound transmitting window sound translative performance, foam core characteristic impedance is close with seawater acoustic characteristic impedance or equal.This practicality
Novel integrated considers requirement of the structure in terms of intensity with acoustic characteristic, and which had excellent after structural strength is met, both
Sound translative performance, the flow noise produced during also suitably reducing shipping agency are disturbed to the signal of sonar array.
