Abstract

As the effect on the interaction between the large vessel’s hull deformation and propulsion system becomes a research hotspot, it is necessary to research the vibration characteristics of the shaft excited by the ship hull deformation to guarantee the reliable operation in the sea. Based on the dynamic equations, this paper aims to establish the dynamic model of the propulsion shaft taking into account the ship hull deformation excitations. The analytical results of the model are compared with the numerical results to confirm that the model is reliable. Based on one typical large container vessel, the shaft vibration characteristics are studied under ship hull deformation excitations with different directions and parameters respectively. Groundwork is made for further research in shaft vibration problem considering ship hull deformation.
