基于STAR-CCM+软件对安装首固定翼的无人艇在顶浪规则波条件下的运动响应和波浪推进航速进行研究。利用DFBI模块建立了波浪推进艇的数学模型，应用SST k-ω模型，结合VOF方法，对波浪推进艇在不同周期和波高条件下的运动响应进行数值仿真，得出波浪推进艇垂荡和纵摇运动频率响应函数(RAO)及航行速度。研究结果表明：随着波高的增大，水翼产生的推力逐渐增大；艇体的垂荡运动响应受波高影响较小，艇体纵摇运动响应由于水翼产生的阻尼效应随着波高增大而逐渐减小；波浪推进艇航行速度随着波高增大先增加而后迅速减小。
The motion response and the speed of the wave-propelled boat with bow fixed foil travelling in head waves was studied based on the STAR-CCM+ software. The mathematical model for the wave-propelled boat was established by using the DFBI module. Using the SST k-ω turbulence model, combined with the VOF method to simulate the motion of the wave-propelled boat in various wave conditions. The response amplitude operator (RAO) of heave and pitch motions as well as the speed of the wave-propelled boat are obtained. The results show that with the increase of the wave height, the thrust force of the hydrofoil increases. With the increase of wave height, the hull heaving motion response remain basically stable while the pitching motion response decreases due to the damping effect of the hydrofoil. With the increase of wave height, the speed of wave propulsion boat increases first and then decreases rapidly.
