Abstract

The thrust bearing pedestal in a propulsion shafting is the main path for longitudinal vibration to transmit from the propeller to the hull. A propeller-shaft-thrust bearing pedestal vibration model is established to study the active longitudinal vibration control, and the four-pole parameters method is adopted to derive the frequency response functions of the disturbance and control channels, and the analysis of active control effect is done through numerical simulation. The simulation results has shown that the adaptive control strategy can reduce longitudinal vibration of the thrust bearing pedestal effectively when the longitudinal control force is exerted on the thrust bearing pedestal. To verify the control method, with research object of shafting system, actuators are mounted on the thrust bearing housing symmetrically, and response to the controller to cancel the effects of the disturbance. Experimental results demonstrate that the control method can suppress the longitudinal vibration of the thrust bearing pedestal effectively, and the peak of power spectrum decreases by about 90% within the 100Hz.
