摘要
风帆助航波浪滑翔器(Sail-assisted Wave Glider,SWG)是一种利用风能和波浪能共同驱动的海上无人航行器,对其机动性能进行准确预测至关重要.本文基于SWG的升沉俯仰运动方式,通过模拟恒定风场和波浪环境,构建了五自由度运动学及动力学模型,并在Matlab/Simulink环境下建立运动仿真程序,以模拟不同海况下SWG的运动性能和回转轨迹.进行了海试,验证所建模型的有效性,反映SWG在真实海况下的运动特性.
Abstract
The Sail-assisted Wave Glider(SWG)is an unmanned marine vehicle that utilizes wind and wave energy for propulsion,making accurate prediction of its maneuvering capabilities crucial.This study focuses on the pitch and heave mo-tion of the SWG.It constructs a kinematic and dynamic model with five degrees of freedom by simulating a constant wind field and wave environment.A motion simulation program is developed in the Matlab/Simulink to simulate the motion per-formance and turning trajectory of the SWG under various sea conditions.Sea trials are conducted to validate the model and reflect the motion characteristics in real sea conditions.
