摘　　要：多波束主要用于考察海底地貌,保证良好的水动力性能可以更有利于多波束的工作。采用势流理论计算舰船水动力系数,进一步采用STF二维切片理论对舰船耐波性进行预报。多波束升力的计算要考虑波浪和纵摇的攻角,合力与升力、重力以及浮力的差值即为多波束与船体间的作用力,精确的计算有利于为多波束提供良好的力学环境保障,对于多波束进行海底作业及其重要。Gondola multi-beam is used to survey sea-floor geomorphology.A fine mechanical property can make gondola multi-beam work well.The potential flow theory is used to calculate the hydrodynamic coefficients,and STF 2D strip theory is used to forecast the vessel's seakeeping.The hydrodynamic force can be accurately calculated by considering the wave and the attack angle of vessel's sway.The resultant force subtracted the force including the lift,gravity and buoyancy force of gondola multi-beam is the force which is acted by the vessel.The accurate calculation can help to supply good mechanical environment to the multi-beam,which is important to the work of multi-beam under sea.
