水深对岸壁效应的影响仿真研究

review of literature on ship-bank interaction is given, with the emphasis on theoretical method and experimental method.Make the simulation software to analyse bank effect by different water depth and give the change of ship motion parameters with the time.Research shows that, with the decrease of water depth,bank suction and yaw torque is increased,but the bank suction does not change significantly.As the water depth decreases further(h/d is less than 1.3),the yaw torque will increase obviously, but the nature of the bank force may be changed, the suction force transition to the repulsive force, the transition occurs when the h/d value is near 1.2.
