摘要
Abstract
A new active method for controlling longitudinal vibration of shafting systems is presented to suppress the vibration of the propeller-shafting-hull coupled system induced by the propeller’s oscillatory forces. The longitudinal vibration controller is symmetrically installed on the pedestal of the thrust bearing to suppress its vibration by feedback control. The vibration of the propeller-shafting-hull coupled system is modeled. On this basis, vibration control and acoustic radiation characteristics of the coupled system are analyzed. The results show that the vibration and radiated noise of the hull caused by the longitudinal excitation can be suppressed. Besides, a shafting experimental platform is set up to evaluate the control effect. Experimental results show that the active actuator can effectively reduce the longitudinal vibration of the pedestal of thrust bearings.关键词
