摘要
岸壁效应对近岸航行船舶的安全性有重要影响,若操作不当常会造成船舶过度与岸壁接近而发生碰撞.文中以系列60(Cb=0.6)船型为例,采用一种一阶Rankine源面元法计算其在浅水域中以恒定速度沿3种不同岸壁航行时受到的横向力和首摇力矩,分析了水深、船到岸壁距离、岸壁倾斜角度以及下潜岸壁高度等对船舶受到的水动力的影响.
A ship sailing along a bank suffers a lateral force toward the bank,as well as a yaw moment pushing the bow away from the bank,due to the unsymmetrical flow induced by the bank;this is the so-called bank effects.Bank effects have a significant impact on navigation safety for a ship traveling along a bank.If improperly operated,the ship may move close to the bank which may lead to ship-bank collision.In this paper,the hydrodynamic lateral force and yaw moment acting on a ship traveling along three kinds of bank in shallow water with a constant speed are calculated by using a first-order Rankine source panel method.Numerical results are obtained for a Series 60（CB=0.6） ship.The influences of water depth,ship-to-bank distance,angle of the sloping bank and height of the immersed bank on the hydrodynamic forces are analyzed.
