船舶在实际海洋环境中的性能代表航行性能的优劣，通过结合海洋环境信息数据来探究船舶的耐波性能以达到对船舶辅助航行的目的，首先使用以切片法为理论的seakeeper软件对船舶耐波性进行仿真研究，获得船舶运动的传递函数和船舶纵摇、升沉、横摇有义值曲线，采用莫尔公式对模拟结果进行验证，通过数值模拟找到对耐波性指标较大的因素，根据耐波性指标衡准对船舶耐波性能做出评价，并应用统计学中的正交试验方法对耐波性的影响因素（航速、风速、航向）对耐波性指标的影响程度进行研究，使海洋环境中船舶的耐波性达到最优，从而起到指导船舶航行的目的。
The ability in the marine environment of the ship can express the sailing performance. In this paper, explore the ship wave resistance through the combination of marine data in order to achieve to the purpose of the auxiliary navigation. Firstly ship seakeeping was simulated by the seakeeper software based on the sectioning theory. The ship motion transfer function and the righteousness value curve of pitching, heave and roll were obtained. The value was verified by Moore formula. The influencing factors of seakeeping were found through the numerical simulation. And the seakeeping performance was evaluated according to the index criterion. The unfeasible region was marked on the map, thus has a certain guiding role for the sailing. The orthogonal experiment statistical methods is applied to study on the influence degree of the influence factors (ship's speed, wind speed and heading) to seakeeping index. So that the seakeeping performance can achieve to the optimum, thereby can realize to guide the navigation purpose.
