风浪流夹角变化对三锚浮标系统运动响应的影响
Effects of Wind-wave-current Intersection Angle Change on Motion Response of Three-anchor Buoy System
摘要
Abstract
In the preliminary design of the three-anchor buoy system,only the collinear wind,wave and current are usually considered,while in the real environment,the load is often non-collinear.In order to explore the influence of wind-wave-current angle change on the motion response of the three-anchor buoy system,a multi-field coupling model of the buoy system is established based on ANSYS-AQWA,and the time-domain analysis of the three-anchor buoy system under the condition of non-collinear load is carried out.The influence of wind-wave-current angle change on the six-degree-of-freedom motion amplitude of the buoy and the tension of the anchor chain is obtained.The results show that when the wind,wave and current loads are collinear,the motion response of the three-anchor buoy system in the surge and pitch directions reaches the maximum when the incident angle is 0°,which is 2.57 m and 8.58°respectively.The motion response of sway and roll reaches the maximum when the incident angle is 90°,which is 2.67 m and 8.43°respectively.The motion response in the yaw direction is the smallest when the collinear load is applied.The motion response in the heave direction is not sensitive to the change of the load angle,and the average change range is not more than 0.6 m.When the load is collinear and opposite to the arrangement of the anchor chain,the tension of the anchor chain also reaches the maximum value of 812.63 kN.Therefore,when calculating the motion response of the three-anchor buoy system and designing the mooring system,the collinear wind-wave-current load can be used as the extreme condition of the load.关键词
