大型船舶在世界远洋运输中发挥的作用越来越突出，提高了运输效率，推动了经济发展。提升航行安全性、可靠性的关键是大型船舶推进系统的多模态耦合问题。船舶在海面上航行受到风、浪、流等不确定因素的影响，本文从船体、推进器、洋流三者之间的耦合出发，通过研究耦合原理，根据耦合动力学中的模态叠加法，建立推进系统动力学模型，最后通过实验计算分析风浪对船舶的动态影响，从而揭示三者耦合的一般规律。

Large scale ships become more and more prominent in the world ocean. Not only improve the efficiency of transportation, and a strong impetus to economic development. The key is multi-modal coupling problems for large scale ships to enhancing security and reliability. Ships sailing in the sea affected by wind, wave, flow and other uncertainties. This paper considers the hull, propellers, coupling between the three currents. By studying the coupling principle and according coupling dynamics of modal superposition method to establish propulsion system dynamics model. Finally, calculate and analyze the dynamic effects of large scale ships because of storm in experiments, which reveals the general laws of the three coupled.
