【摘要】 穿浪双体船作为一种高性能船舶，在快速性、稳定性和耐波性等各项性能上都表现优良，其高速轻盈、适用航区广，即使在恶劣海况下也能灵活穿梭，是海上高速客船、公务船、快艇等的首选船型。在我国，穿浪双体船的应用正在逐步推广，被重视程度也越来越高，因而对穿浪双体船的性能进行研究具有十分重要的意义。本文主要研究了穿浪双体船的阻力计算方法和耐波性理论预报方法，开展了以下几个方面的研究工作：（1）以双体船的Michell型兴波阻力计算公式为基础，运用帐篷函数法表达穿浪双体船的船体曲面，同时对方尾影响进行修正，从而建立出穿浪双体船的兴波阻力计算公式。对穿浪双体船WPC-X进行了阻力计算，与模型试验数据进行了比较，探讨了兴波阻力和总阻力的变化规律。进一步对不同片体间距下的兴波阻力进行了计算，分析得出了穿浪双体船片体间距变化对兴波阻力的影响规律。（2）切片理论是船舶运动预报的主要方法，本文运用Frank密切拟合法计算二维流体辐射速度势，采用修正的切片法，同时考虑流体粘性作用的影响，在频域内对穿浪双体船的耐波性进行了理论预报研究。对穿浪双体船WPC-X在规则波上的纵向运动进行了理论计算，计算结果和模型试验数据进行了比较，验证了此预报方法的可行性。在此基础上，进一步预报了穿浪双体船在不规则波上的运动响应。更多还原

【Abstract】 As a high-performance ship, the wave-piercing catamaran is doing well in muchaspect, especially in the performance of speedy, stability and seakeeping. WPCs arehigh-speed and appropriate to varied usage and sea area, even in adverse sea conditionsthey also can keep stable navigation. In China, the application of WPC is graduallyextended, so there is a very important significance in the research on WPC’s performance.First, based on the Michell formula of the catamaran and using the tent function toexpress the wave-piercing catamaran hull surface，a wave-making resistance formula forwave-piercing catamaran is suggested. The resistance of certain WPC is calculated bymeans of this method. Its results are compared with the experimental results, and theresistance regulations of WPC are investigated. Some meaningful conclusions are drawnthrough studying the influence of the hull space of WPC on its wave-making resistance.Second, frank source distribution method is used to calculate the two-dimensionalfluid potential and the hydrodynamic coefficients. The research use STF method，takinginto account the fluid viscous effect，to predict the longitudinal motion performance ofwave-piercing catamaran. The longitudinal motion of certain WPC is calculated by meansof this method. The comparison of the calculation results and experimental data show thatthe method of this paper can well predict the motions of wave-piercing catamaran.更多还原
