| 摘 要： | 应用线性船舶水动力学理论,将有限水深开尔文移动兴波源格林函数分解成Rankine源集合、局部扰动项和波函数项3部分,利用高斯拉盖尔及最速下降积分方法加快了局部扰动项的计算速度.采用面元法计算了有限水深船体表面的面源强度,并与无限水深结果进行对比,进一步求解出有限水深船舶的兴波阻力,与其他方法所得结果基本一致,在跨临界航速中有限水深兴波阻力明显大于无限水深的结果.

| Abstract: | Applying linear marine hydrodynamics theory,the Kelvin wave source Green function of steady motion was divided into three parts: the array of Rankine sources,the local disturbance and the wave part.The Gauss-Laguerre and steepest descent integration method was used to increase the calculation speed of local disturbance part.The panel source strength on ship surface in finite depth was calculated by panel method.The results were compared with the ones of deep water.The wave resistance of ship in finite depth... |
