摘　　要：船舶数量与尺寸的不断增加导致其在限制水域船舶水动力干扰现象突出,限制水域内的船舶水动力干扰的快速准确预报,有助于船舶智能航行安全的发展。针对此问题,本文提出了一种基于Hess&Smith面元法的数值方法,实时计算浅水中两船平行干扰与会遇过程中的船-船水动力干扰问题。基于低弗劳德数假设,使用合模方法处理自由液面处的边界条件,并使用镜像法处理水平水底处的边界条件。本文通过将数值结果与有限的试验结果对比,验证了该实时计算方法的可行性,确定了该方法的适用范围。Due to the continuous increase in the number and size of ships,the problem of hydrodynamic interference in restricted waters has become more prominent.The rapid and accurate prediction of ship hydrodynamic interference in restricted waters can not only ensure the safety of ship navigation but also promote the development of ships in the direction of intelligence.To answer this problem,a numerical method based on the Hess-Smith panel method is proposed in this paper to calculate ship-ship parallel hydrodynamic interference in shallow waters in real time.Based on the assumption of low Froude number,the double-body method and the mirror image method are used to deal with the boundary conditions of the free surface and the horizontal bottom,respectively.This paper validates the feasibility of the real-time calculation method by comparing the numerical results with the limited experimental results.This paper also determines the method′s scope of application.
