摘　　要：耐波性能一直都是船舶水动力性能研究的重点。基于计算流体动力学(Computational Fluid Dynamics,CFD)数值仿真方法,以高速双体船为切入点,综合研究其在复杂海况下的耐波性能。基于Fluent建立双体船等比例仿真模型,运用流体体积(Volume of Fluid,VoF)数值造波技术进行数值造波。针对三级以下的海况进行规则波耐波性能研究,获得不同波长下纵摇、升沉运动幅值算子响应曲线。结果表明,在规则波下,不同波长双体船纵摇及升沉幅值相对变化均较小,说明该船体结构在三级海况以下耐波性较好。但是,波长在60 m时,纵摇及升沉运动出现峰值,会导致船体的耐波性较低。Seakeeping performance has always been the focus of ship hydrodynamic performance research. Based on the Computational Fluid Dynamics(CFD) numerical simulation method, taking high-speed catamaran as the breakthrough point, the seakeeping performance in complex sea conditions is comprehensively studied. And establishes a proportional simulation model of a catamaran based on Fluent, and conducts numerical wave-making based on Volume of Fluid(VoF) numerical wave-making technology. The response curves of the pitch and heave motion amplitude operators under different wavelengths. The results show that the relative changes of pitch and heave amplitudes of the catamaran with different wavelengths are small under regular waves,indicating that the hull structure has better seakeeping under the third sea state. However, under the condition of 60 m wavelength,the pitch and heave motion peaks, and it will lead to the low seakeeping performance of the hull.
