Abstract

Abstract

When an underwater vehicle is in motion, the propeller will generate significant low-frequency line spectrum radiation noise. To verify the control effectiveness of different active control strategies on the line spectrum radiation noise, an active control experiment on the radiation acoustic field was conducted for the first time on a real small-scale propeller. An underwater test platform, which includes a propeller, sensors, secondary force actuators, secondary sound sources, and a control system, was constructed for active noise control(ANC), active vibration control(AVC), and active noise and vibration control(ANVC) tests. By altering the working conditions of the propeller, the suppression effects of different control strategies on the underwater radiated sound pressure of the propeller were tested. The results show that active noise control has a significant and stable effect on suppressing the low-frequency line spectrum noise of the propeller, and performs best under high rotational speed conditions; active vibration control has limitations and local control may lead to sound field reconstruction; active acoustic-vibration combined control shows potential for collaborative control in some operating conditions, but the control strategy and collaborative mechanism need to be further optimized. The research results provide an experimental basis and technical support for the engineering control of underwater propeller radiated noise.
