大型船舶的船体变形与其推进系统之间的耦合影响成为船舶领域的研究热点，开展船体变形激励下的推进轴系振动性能的研究对保证船舶可靠运行十分必要。文章以船舶轴系动力学方程为研究基础，建立其计入船体变形激励的大型船舶推进轴系的动力学模型并通过解析解与数值解的对比验证了方法的可靠性。依据此模型，以某大型集装箱船舶为研究对象，分别探索了船体变形激励不确定方向下以及变尺寸参数下轴系振动的影响规律，为大型船舶船体变形激励下的轴系振动问题提供了理论基础。

As the effect on the interaction between the large vessel’s hull deformation and propulsion sys-tem 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 con-firm that the model is reliable. Based on one typical large container vessel, the shaft vibration characteris-tics 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.
