摘　　要：在不同船型的船体下安装半主动弹性摆翼,可使船舶在波浪中航行时实现摆翼增推效应,以达到船舶减阻增推的目的。论文应用FINE/Marine软件实现波浪中船舶与半主动弹性摆翼的联合模拟,对一系列标准船模(DTMB 5415型、KVLCC2型、Wigley型、KCS型)的摆翼减阻增推效应进行对比分析。设计各型船模的摆翼并进行数值分析,在相似的工况和摆翼设计参数下对比了不同船型上摆翼的减阻增推效应。结果表明,设计的摆翼可提高近20%的推力,船首摆翼位置的运动幅值减小了约15%,起到了减小船体运动幅度的作用。对比分析了摆翼安装位置及摆翼尺寸对减阻增推效应的影响,结果表明,安装在船首位置的摆翼减摇和减阻增推效果最好,增大摆翼尺寸也可增强摆翼的减摇和减阻增推效果。Semiactive elastic swing foils are installed under different types of hulls sailing in waves to increase thrust and reduce resistance. Software FINE/Marine is applied to achieve joint simulation of ships and semiactive elastic swing foils in waves for a series of standard ship models(DTMB 5415, KVLCC2, Wigley, and KCS). A grid-independent analysis of the numerical method was conducted, and the results in calm water and waves agreed well with the experimental results of ship models. Numerical results show that the preliminary design of the swing foil can increase thrust by nearly 20%, and the motion amplitude at the position of the bow swing foil is reduced by about 15%. A comparative analysis is conducted on the influence of the installation position and size of the foil on increasing thrust and reducing resistance. It is shown that the swing foil installed at the bow had the best anti-pitch and anti-resistance effect. Increasing the size of the swing foil will also enhance the anti-pitch and anti-resistance effect.
