SENSOR PHONONIC CRYSTAL VIBRATION ISOLATOR FOR UNDERWATER VEHICLE

WIPO Patent Application WO/2024/007357

A1

The present invention relates to the technical field of underwater detection devices. Disclosed is a sensor phononic crystal vibration isolator for an underwater vehicle. The sensor phononic crystal vibration isolator comprises a front connecting part, a rear connecting part, elastic annular parts and rigid annular parts, wherein the front connecting part is configured to be connected to an acoustic sensor of the underwater vehicle; the rear connecting part is configured to be connected to a fairing of the underwater vehicle; the elastic annular parts and the rigid annular parts are each provided with two annular end surfaces; a plurality of elastic annular parts and rigid annular parts are sequentially and alternately arranged to form a cylindrical vibration isolation body, and the cylindrical vibration isolation body is connected between the front connecting part and the rear connecting part. By means of the vibration isolator, propagation of mechanical noise of the underwater vehicle to the acoustic sensor end can be effectively blocked, so that the working performance of the acoustic sensor of the underwater vehicle is enhanced.
