摘　　要：船舶逐步向标准化、大型化的方向发展,有效减少或避免大型船舶对码头碰撞是工程领域亟待解决的问题。采用ANASYS-AQWA仿真软件,基于三维势流理论与时域分析方法,结合山区河流水流湍急、流量变幅大的特点,采用数值分析的方法,研究了船舶在不同系泊方式下的系泊运动响应特性。研究结果表明:0°和180°的浪向角对纵荡幅值响应算子的影响最明显;90°的浪向角对横荡、垂荡和横摇响应较大,对纵荡、纵摇和艏摇影响较小;2-7-2系泊方式对于船舶的横向运动限制更好;4-4-4系泊对于船舶的纵向运动限制更好。Ships are gradually developing in the direction of standardization and large scale.It is an urgent problem to be solved in the engineering field to effectively reduce or avoid the collision between large ships and wharves.Based on the three-dimensional potential flow theory and time-domain analysis method,and in combination with the characteristics of turbulent flow and large flow variation in mountainous rivers,the mooring motion response characteristics of ships under different mooring modes were studied by adopting the numerical analysis method and ANASYS-AQWA simulation software.The research results show that the wave direction angles of 0°and 180°have the most obvious effect on the amplitude response operator of surge,and the wave direction angle of 90°has a larger response to sway,heave and roll,and a smaller impact on surge,pitch and yaw.The 2-7-2 mooring mode has a better restriction on the lateral movement of ships,while the 4-4-4 mooring mode has a better restriction on the longitudinal movement of ships.
