摘　　要：采用两种方法相耦合的算法计算了航行船舶产生的尾浪对系泊船舶的影响,以基于NURBS的广义边界元方法对航行船舶产生的尾浪进行了预报,基于线性势流理论和Cummins的间接时域理论,以航行船舶产生的尾浪作为输入边界,数值模拟了系泊船舶在航行船舶尾浪中的运动情况.计算结果与试验结果的比较,表明了文中采用方法的可行性.文中还讨论了航行船舶速度、水深、两船间距等对系泊船舶在船舶尾浪中的运动响应的影响.The coupling algorithm of the two methods was used to analyze the influence of the stern wave generated by the sailing ship on the mooring ship. In this paper, a generalized boundary element method based on NURBS was used to predict the wash wave generated by sailing ships. Based on the linear potential flow theory and Cummins’ indirect time domain theory, the motion of moored ships in the wash wave of sailing ships was numerically simulated with the wash wave generated by sailing ships as the input boundary.The comparison between calculated results and experimental results shows that the method adopted in this paper is feasible. The paper also discusses the influence of sailing ship speed, water depth and distance between ships on the motion response of moored ships in the wash wave.
