摘　　要：为研究风翼助航船舶在波浪中的稳性,以一艘46 000 t油轮为目标船,首先,根据目标船的船型数据,在Maxsurf软件中进行三维建模并验证其正确性;其次,将航行时船舶与波浪的相对位置分为4种情形,分析加装风翼后船舶在不同的船-波位置中的稳性变化.结果表明,波峰在船中部且波长近似于船长时,船舶稳性下降较大.最后,通过Matlab软件选取随机数的方法模拟船舶航行时的随机风浪,计算船舶在加装风翼后航行的安全可靠性.由船舶在8级风级下的最危情况可以看出,加装风翼后船舶的航行安全性要低于未加装风翼的船舶,并且存在4.77%的倾覆概率.To study the stability of the sail-assisted ship in the wave,taking a 46 000 t tanker as the target ship,firstly,according to the data of the target ship,the ship 3 D modeling was established by using Maxsurf software and its correctness was verified. Secondly,the relative position of ship and wave was divided into 4 cases to analyze the stability of the sail-assisted ship in different ship-wave positions. Results show that when the peak is located in the middle and the wavelength is approximately equal to the ship＇s length,the ship＇s stability decreases greatly. Finally,the random number was selected by Matlab software to simulate the random waves in the course of ship sailing,and the safety and reliability of the ship with wind wings were calculated. According to the most dangerous situation such as ship sailing at 8 level,the safety of the ship with sail-assisted is lower than that without wing,and the capsizing probability is about 4. 77%.
