Abstract
The invention relates to the technical field of underwater sound equipment, in particular to a flexible co-oscillating vector hydrophone suspension device. The flexible co-oscillating vector hydrophone suspension device comprises a hydrophone body and a rigid supporting body. Flexible rubber is filled between the hydrophone body and the rigid supporting body. Preferably, the flexible rubber is filled between the two opposite side faces of the hydrophone body in the horizontal direction and the rigid supporting body or between the two end faces of the hydrophone body in the vertical direction and the rigid supporting body or between all the surfaces of the hydrophone body and the rigid supporting body. The flexible co-oscillating vector hydrophone suspension device has mechanical supporting and locating effects for a co-oscillating vector hydrophone, and is good in elasticity and softness and capable of ensuring that the co-oscillating vector hydrophone and medium mass points can keep the same oscillation under the action of sound waves as far as possible.
Description
Technical field
The present invention relates to underwater sound equipment technical field, especially a kind of same vibration shape vector hydrophone spring suspension device.
Background technology
With vibration shape vector hydrophone, be the sensor of place, vector hydrophone position particle vibration characteristic in picked up water sound field, the particle vibration information of picking up comprises particle vibration velocity, vibration acceleration isovector information.Compare with traditional sound pressure sensor, vector hydrophone can obtain the more sound field information of horn of plenty, for Underwater acoustic signal processing, will provide more abundant, more efficiently analysis means.
Physical dimension is much smaller than the similar same vibration shape vector hydrophone of the density of wavelength and its average density and acoustic propagation medium, when it is placed in sound field by suitable resilient suspension system suspension, vector hydrophone can be subject to the combined action of sound wave and the vibration of rippling, and the characteristic of vibration and the vibration of medium particle are basically identical, utilize vibration velocity sensor or the accelerometer of vector hydrophone indoor design just can effectively pick up the vibration vector information of vector hydrophone, vector hydrophone just can be realized the measurement to particle vibration information in sound field like this.
The resilient suspension of vector hydrophone is the key that guarantees that vector hydrophone correctly picks up sound field Vector Message, not only require system to there is the effect that mechanics supports and locates to same vibration shape vector hydrophone, also need support system to there is good elasticity and flexibility, guarantee the vibration that vector hydrophone can be identical as far as possible with the maintenance of medium particle under the effect of sound wave.
The resilient suspension system of traditional same vibration shape vector hydrophone adopts rubber strip, spring etc. as flexible member, utilize some groups of flexible members, to be suspended on specific rigidity supporting structure with vibration shape vector hydrophone symmetrically, but rubber strip is easily aging, spring was used elasticity of a specified duration easily to change, and therefore can affect the precision of vector hydrophone, in addition, while using spring as the suspension of nautical receiving set, process and make also more complicated.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of same vibration shape vector hydrophone spring suspension device, this spring suspension device have be difficult for aging, can be accurately to the sound field Vector Message of nautical receiving set Transfer Medium, and processing and easy to make.
In order to solve the problems of the technologies described above, the present invention includes nautical receiving set body and rigid support body, between described nautical receiving set body and rigid support body, be filled with flexible glue.
Preferably, between two opposite flanks of described nautical receiving set body horizontal direction and rigid support body, be filled with flexible glue.
Preferably, between two end faces of described nautical receiving set body vertical direction and rigid support body, be filled with flexible glue.
Preferably, between all surface of described nautical receiving set body and rigid support body, be filled with flexible glue.
Preferably, described flexible glue is silicon gel.
Hang and compare with the traditional elastic of vector hydrophone, the present invention:
1, there is longer serviceable life;
2, structure is compacter, light and handy, can improve the suitable dress property of platform of vector hydrophone sensor-based system;
3, can be using flexible glue as acoustic coupling material and insulation-encapsulated materials'use, make whole same vibration shape vector hydrophone sound sensor-based system more succinct;
4, can effectively control the whole proportion of vector hydrophone and resilient suspension system, be conducive to design and the use of the floating sound sensor-based systems such as towed array cable;
5, obtain wider service band relatively easy.
