摘　　要：深海海底钻机收放系统在风、浪等海洋环境的扰动下会引起海底钻机摆动,通过建立收放系统的动力学模型,分析收放系统在规则波浪下不同波高、浪向角和风速对海底钻机摆角以及相对位移的影响.研究结果表明:在波高、浪向角以及风速的影响下,深海海底钻机入水前后的摆动角度与相对位移变化均存在明显差异;随着波高与风速的增大,钻机的面内摆角变化幅度较小;随着浪向角的增大,钻机的摆动角度和相对位移逐渐增大.得到的结论可用于海底钻机收放系统摆动的预测和控制,为技术工作人员提供参考.Based on the launch and recovery system of seafloor drill will cause the seafloor drill to swing under the disturbance of the marine environment such as wind and waves.By establishing the dynamic model of the launch and recovery system,the different wave heights,wave direction angles and wind speeds of the launch and recovery system under regular waves are analyzed.Influence on the swing angle and relative displacement of the seafloor drill.The research results show that under the influence of wave height,wave direction angle and wind speed,there are obvious differences in the swing angle and relative displacement of the deep-sea submarine drilling rig before and after entering the water.With the increase of wave height and wind speed,the in-plane swing of the seafloor drill.The angular variation range is small,the variation range of the out-of-plane swing angle increases accordingly,and the relative displacement also increases continuously;with the increase of the wave direction angle,the swing angle and relative displacement of the seafloor drill gradually increase.The obtained conclusions can be used for the prediction and control of the swing of the launch and recovery system of the seafloor drill,and provide reference for the technical staff.
