Embodiment Construction
[0018] Referring to the accompanying drawings, a device for suppressing flow-induced oscillation line spectrum noise in an underwater cavity includes: a solenoid 1 , a driving membrane 2 , a hydraulic cylinder 3 , a top cover 4 , a bottom cover 5 , and a base 6 .
[0019] Solenoid 1 is a multi-wound coil wrapped on the surface of the magnetic core and integrated into the package. It extends three tentacles and inserts them into three small holes reserved on the lower end surface of base 6; when solenoid 1 is energized, the three The electromagnetic force generated by the tentacles causes the driving membrane 2 to make periodic piston movements along the axial direction of the hydraulic cylinder 3;
[0020] The driving film 2 is selected from common electrostrictive materials, and the thickness is determined by the required jet velocity.
[0021] The hydraulic cylinder 3 is located in the inner cavity of the base 6, the lower end surface of the hydraulic cylinder 3 is connected...
