Abstract

The invention discloses a single unit rotation type combined gas explosion sound source, and belongs to the technical field of naval mine resistance. The gas explosion sound source comprises a servo motor, a rotor, a stator shell, a piston and a piston cylinder; a cavity part of the rotor, which is provided with release holes, is inserted into the inside of the stator; both ends of the piston arerespectively positioned in the rotor and the piston cylinder; the piston cylinder is coaxially abutted with the stator shell; high-pressure gas inside the rotor is discharged and released by periodicopening and closing of the corresponding release holes on the rotor and a stator so as to generate a series of acoustic wave pulses oscillating on a wide band in water; by regulating displacement of the piston in the rotor, the number of opened ports of the rotor is controlled to regulate strength of the sound source; and the rotor is driven to rotate by the servo motor, when the opened release holes of the rotor are coincided with the release holes of the stator, a pulse with a specific frequency spectrum is generated, and the continuous change of the opened ports of the rotor in the continuous transmission process implements smooth control of the frequency spectrum. According to the invention, a physical field generated by a ship can be effectively simulated.

Description

technical field

[0001] The invention relates to a combined gas explosion sound source, in particular to a rotary combined gas explosion sound source, which belongs to the technical field of anti-mine. Background technique

[0002] It is well known that the total noise spectrum radiated by ships is composed of continuous broadband noise spectrum and narrowband line spectrum components at several discrete frequencies. When performing ship noise signal simulation calculations, the more commonly used method is to divide the power spectrum of ship radiation noise into two types: one is broadband noise with continuous spectrum, and its noise level is continuous, and broadband stationary random noise can be used. The process produces a continuous spectrum; the other is a discontinuous single-frequency noise, which is composed of a line spectrum appearing at a discrete frequency, and a periodic signal can be used as a line spectrum model.
