摘　　要：浮式激光雷达测风塔在恶劣的海洋环境下,其运动稳定性受到风、浪、流等多种环境载荷的耦合作用,呈现出典型的非线性特征,对其观测精度造成重要影响。建立浮动式基础设计分析平台,对浮标及其系泊系统进行水动力性能模拟分析,求解不同载荷作用下浮标平台与单点式系泊系统之间的运动响应。计算结果表明,浮标体在单点式系泊方案下具有良好的安全性和稳定性,系泊张力最大值为466.4k N,满足设计BVNR493规范要求,浮标平台的运动半径极值和最大垂荡距离分别为50.0m和6.3 m,可保证安全运行。When the floating LIDAR wind tower operates in the harsh ocean environment,its motion stability is affected by the coupling environmental loads such as wind,wave and current,showing typical nonlinear characteristics,which has an important influence on its observation accuracy.A floating foundation design analysis platform is established to analyze the hydrodynamic performance of the buoys and its mooring system,and to solve the motion response between the buoys and its mooring system under different loads.The results show that the buoys under the single point mooring scheme has good security and stability.The maximum mooring tension is 466.4 kN,which can meet the BV NR493 specification.The maximum movement radius and maximum heaving distance of the platform are 50.0 m and 6.3 m,respectively,which can ensure the safe operation.
