Experimental Study on Dual-channel Active Control Method for Transverse Vibration of Ship Propulsion Shaft System

The ship propulsion shaft system is an indispensable power component of the ship, and its stability and reliability are crucial to the safety of the ship. The transverse vibration of the ship’s shaft system in the operating condition is a serious threat to the safety of ship operation. Therefore, it is of great engineering significance and research value to control the transverse vibration of ship propulsion shaft system and ship hull vibration control.Based on the vibration control theory, adaptive filtering and Fx-LMS algorithm, the active control scheme for transverse vibration of ship propulsion shaft system is studied, and the control scheme is optimized for the shortcomings. Finally, the effectiveness of the active control scheme of ship propulsion shaft system transverse vibration proposed in this paper is verified through the test.The research results show that the ship propulsion shaft system can effectively suppress the ship shaft system transverse vibration caused by propeller pulse excitation by adopting the active control scheme of transverse vibration proposed in this paper, which has a good control effect and provides a new technical reference for the ship shaft system transverse vibration control.
