目前国际上尚未建立波浪中船舶耐波性和操纵性统一的力学模型。研究船舶在波浪中的波频运动和操纵低频运动的耦合不仅具有重要的理论意义，从贯彻党的十九大“加快建设海洋强国”的精神出发更具有重大的实践价值。在静水中和中低海况下能够达到操控目标的船舶，在高海况环境风浪漂移载荷作用下并不一定能够达到操控要求。本项目针对高海况下船舶最小安全功率的设计方法发展需求，分析船舶耐波性和操纵性各自学科原有数学物理分析方法解决此问题的不足，聚焦两个关键科学问题：巨浪条件下船舶耐波与操控耦合动力学,以及船体操纵分离涡与扰动波之间的干扰机制开展研究。提出船舶耐波和操纵耦合水动力学新模型，创新非线性自由面条件下船舶波频摇荡运动和低频漂移运动扰动流场求解数值方法，设计船模试验并开展水动力和典型运动参数的验证试验，建立船舶耐波性和操纵性耦合流体动力学，为船舶节能设计和安全航行高效模拟分析奠定理论基础。

It has not been established that the unified mechanical model of ship's seakeeping and maneuverability in waves. The research of ship seakeeping and the maneuverability coupling in waves not only has important theoretical significance, From implement the communist party's 19 congress "to speed up the construction of sea power” spirit is of great practical value. Even it can achieve the goal of control of ship at calm water or low sea condition , under the wind wave drift force action in high sea state environmental , is not necessarily can satisfy the control requirement. This project aimed at high sea condition of minimum safe power for ship design requirements. Facing the shortcomings of original mathematical physics analysis theory to solve this problem of ship's seakeeping and maneuvering subject. Focus on two key scientific problems: coupling dynamics of ship's seakeeping and maneuvering under huge ocean waves , Interference mechanisms between hull separation vortex with the hull disturbance wave. The new model will be put forward for Hydrodynamics of coupled ship seakeeping and maneuvering. For nonlinear free surface condition, Innovation of numerical solving method for ship wave oscillation frequency and low frequency drift motion disturbance will be presented. Model design and test of hydrodynamic parameters and validation test of typical motion parameters will be finished. All the above research will establish the theory basis for ship energy efficiency design and safe navigation and efficient simulation.
