摘　　要：阻流板的安装会改变船舶艉部流场,影响船舶的阻力性能以及航行姿态。为了探究阻流板的作用机理,本文选取了三种不同深度的阻流板和一种阻-压浪板,比较阻流板安装前后船舶阻力以及航态的变化,分析船艉压力、流线分布等流场中流动细节的改变。试验及计算结果表明:当船舶航速较高时,合适深度阻流板的安装能达到减阻效果,减阻率可达7.52%;船舶阻力的减小,主要是由于船舶艉部流场的改善,减小了船舶的兴波阻力;阻-压浪板的减阻性能要优于阻流板单独使用时的效果,减阻率可达8.81%。The installation of interceptor will change the flow field around stern,and affect ship' s resistance performance and navigation attitude. In order to explore the mechanism of the action of interceptor,three different depths of interceptor and an interceptor-stern flap were selected to compare the change of navigation state and resistance of the ship before and after installation of interceptor,and analyse the change of flow details in the flow field,such as distribution of stern pressure and streamline. The following conclusions can be drawn: the installation of appropriate depth of interceptor can achieve drag reduction effect when the ship speed is high,and the resistance-reduction rate can reach 7. 52%; the decrease in ship resistance is mainly due to improvement of the flow field around stern,which reduces the wave resistance of the ship; finally,the drag reduction performance of interceptor-stern flap is better than that of interceptor,and the resistance-reduction rate is up to 8. 81%.
