摘　　要：本文以国际标模ONR内倾船为研究对象,首先对数值计算方法进行简要介绍,通过构建的数值波浪水池,建立方形波浪的数值模拟方法。最后,建立方形波浪中船舶运动的数值模拟方法,分析典型方波条件下,不同浪向、航速和波陡中船舶的非线性运动特性,并与单向规则波中的运动进行对比分析。研究结果表明:船舶在方形波浪中的运动响应幅值随着航速和波陡的增加而增加;在某些方形波浪条件下,船舶运动响应明显大于规则波下的运动响应;减小航速和选择合适的航行线路,可以有效提高方形波浪下的航行安全。本文研究可为船舶在方形波浪中的航行性能评估和安全操控提供参考。In this paper the international standard model ONR tumblehome are taken as an example,firstly,the calculation method is introduced.Then the numerical simulation method of cross wave is established by numerical wave tank.At last,based on the established simulation method of ship motion in cross wave,the nonlinear characteristics of ship motion with different wave headings,speeds and wave slopes are studied under typical cross wave conditions,and the results are compared with the motion in regular wave.The research shows that the motion responses of ship increase with the higher speed and wave slope in cross wave;The motion responses of ship are generally much greater than those in regular waves under some cross wave conditions;The sailing safety of ship when subjects to cross waves can be improved by reducing the speed and adopting the reasonably navigational route.The research in this paper would provide useful preference for evaluating the sailing performance and safely controlling of ship in cross waves.
