摘　　要：本文介绍了海上漂浮平台运动模拟器的设计和应用。为了模拟测风激光雷达在海上的工作环境,验证测风激光雷达在非稳定平台的风场计算算法,设计了一套六自由度运动平台模拟器,平台可以按浮标实测数据运动或按固定振幅频率正弦数据运动,搭载激光雷达进行测风实验。本文将两台激光雷达分别处于静止和运动状态进行测风,研究平台运动速度对风场反演的影响。结果显示,平台静止时两台雷达风速平均误差最小,为0.0198 m/s,风向平均误差与最小风向平均误差基本相同,为2.0219°。随着平台运动速度的增加,风速和风向的反演误差也随之增加。该平台能够模拟海上漂浮平台的运动,搭载海上测风激光雷达进行实验,且分析结果能为风场反演算法的优化提供参考。This paper introduces the designing and application of floating platform motion simulator.To simulate wind lidar working environment,validation of wind lidar wind field calculation algorithm in a stable platform,design a 6-DOF motion platform simulator.The platform can move according to the measured data of buoy or sinusoidal data with fixed amplitude and frequency,and carry out wind mea-surement experiment with lidar.This paper will be two lidars wind respectively in stationary and motion state,the research platform velocity influence on wind field inversion.The results show that when the platform is stationary,the average error of wind speed of the two lidars is the minimum,which is 0.0198 m/s.The average error of wind direction is basically the same as that of the minimum wind direction,which is 2.0219°.With the increase of the platform speed,inversion error of wind speed and direction also increases.Movement of the platform can simulate floating platform and carry wind lidar experiment.The analysis results provide reference for wind field inversion algorithm optimization.
