Abstract

Serving as the heart of ship, marine propulsion system is the most important power source. The longitudinal vibration power flow in the marine propulsion shaft-line is investigated theoretically and experimentally in this paper. The longitudinal vibration power flow analysis on marine propulsion shaft-line has been implemented using governing equations of continuum mechanics. In developing the mathematical model of marine propulsion shaft-line, the longitudinal vibration is defined theoretically. The concept of energy flow density and energy flow line are introduced in the models. A simulation model has been established to describe the properties of the longitudinal vibration power flow in the marine propulsion shaft-line. Analysis results show that the power transmission trend is along the shaft-line in longitudinal vibration. The total longitudinal vibration power flow predicted by the developed model was also compared with that tested using a MetaPower device. It was shown that the developed model provides a more accurate prediction of the total longitudinal vibration power flow of marine shafting in the frequency range of interest.
