| 摘 要： | 穿浪双体船船型复杂,航速较高,要准确预报其波浪载荷比较困难,但同时对于结构设计而言又非常重要。基于线性势流理论,采用三维流体动力学方法在时域上计算了穿浪双体船的运动响应和波浪载荷,时域计算结果经过傅立叶变换,在频域上分析了其响应特征。通过与规则波中试验结果和数值计算结果进行比较分析,表明用该方法计算穿浪双体船的船体响应可以获得比较满意的结果,可应用于同类船舶的波浪载荷预报。

| Abstract: | Accurate prediction on the wave load of wave-piercing catamaran(WPC) is a difficult job due to its complexity and high speed performance.Based on linear potential theory,a 3D hydrodynamic method was proposed to calculate the motion response and wave loads of WPC in time domain.The numerical results were analyzed on frequency domain after fast Fourier transforming,and was then compared with the experimental results in regular waves.The result indicates that the proposed hydrodynamic method can successfully p... |
