摘　　要：论文针对某新型船舶,将其实际船体参数引入到海浪干扰模型和船舶运动模型中,通过建立的Matlab仿真平台进行模拟仿真,利用控制变量法探究该船舶在不同海况、不同航向和不同航速下受海浪影响产生横摇角的变化规律。根据横摇角随影响因子的变化规律设计船舶可能遇到的恶劣条件,仿真探究该新型船舶在恶劣条件下的横摇运动,分析该新型船舶耐波性和安全性。通过实验得出该船舶在海浪影响下的可产生剧烈横摇运动,分析得到需要合理利用减摇方式进行对该船舶的减摇。论文针对具体船舶进行研究具有重要的现实意义。In this paper,for a new type of ship,the actual hull parameters are introduced into the wave interference model and the ship motion model.This simulation is carried out through the established Matlab simulation platform.The control variable method is used to explore the ship under different sea conditions,different headings and different speeds.The variation of the roll an gle is caused by the influence of the waves.According to the variation law of the roll angle with the influence factor,the harsh condi tions that the ship may encounter are designed.The roll motion of the new ship under severe conditions is simulated,and the wave resistance and safety of the new ship are analyzed.Through experiments,it can be concluded that the ship can produce severe roll motion under the influence of the waves,and the analysis needs to use the anti-rolling method to shake the ship reasonably.It is of great practical significance for the ship to conduct research on specific ships.
