摘　　要：随着海洋工程的发展,海上作业需求日趋多样化,对高性能船舶的快速性也有了更高的要求。该文以某无人双体船为研究对象,基于流体仿真软件STAR-CCM+进行船舶水动力和运动仿真模拟,研究了割划式水翼提高该船快速性的功效。验证网格收敛性并对比原船拖曳实验验证方法精度后,选定了较合适参数的水翼,对比归纳水翼不同安装位置的仿真结果,得到了确保抬升效果的水翼垂向位置范围、前后水翼横向位置对水翼干扰和效率的影响以及通过水翼纵向位置调整船舶航态的方法。总结上述因素对快速性的影响,最终得到了几组快速性较高的参数方案,方案中最大航速达到41 kn,相较原船提升约46%。With the development of marine engineering,the demand for offshore operations is becoming more and more diversified,and there are higher requirements for the speed of high-performance vessels.This study focuses on evaluating the efficacy of surface-piercing hydrofoils in enhancing the speed performance of an unmanned catamaran,employing Computational Fluid Dynamics(CFD)software STAR-CCM+for hydrodynamic and motion simulation of the catamaran.Following the validation of mesh convergence and comparison with the towing experiment of the catamaran to ensure methodological robustness,the appropriate parameters of hydrofoils are selected.Through comparative analysis of simulation results across varied installation positions of hydrofoils,determination of the vertical position range for hydrofoils to attain lift effect,assessment of the lateral positions of fore and aft hydrofoil on interference and efficiency,and methods for adjusting the ship's navigation attitude through longitudinal position adjustment of hydrofoils have obtained.Synthesizing the factors influencing speed performance,several sets of optimized hydrofoil parameters are identified.In these sets,a maximum speed of 41 kn can be achieved,representing a substantial 46%increase over the original catamaran's performance.
