| 摘 要： | 利用三维势流理论和简单格林函数计算了迎浪航行时不同航速和不同水深组合下的波浪运动响应和载荷传递函数,研究不同水深和航速组合对三体船的波浪运动响应和波浪载荷的影响,并对船舯垂向弯矩和舯后1/4船长处剪力进行了长期预报.将预报值与规范值进行比较,结果令人满意.计算结果表明三体船在不同水深下航行时,水深对其运动响应和波浪载荷都会产生显著影响.

| Abstract: | The influence of water depth and speed on motion response and wave loads of trimaran was remarkable.The three-dimensional potential theory and Green's function were used to calculate the transfer function of motion response and wave loads of a trimaran travelling in head sea with several speeds,and the corresponding long term prediction of mid-ship section's vertical bending moment and 1/4 ship length after mid-ship section's vertical shear force were also obtained.Compared with the result of standard,the n... |
