摘要

摘要: 波浪滑翔器的被动扑翼机构是为其提供前向驱动的核心模块, 其推进效率直接影响波浪滑翔器的前进速度和控位精度。文中搭建了完整的被动扑翼推进效率分析构架, 建立了被动扑翼推进运动计算流体力学(CFD)仿真模型, 重点对二级海况下的被动扑翼加载扭簧情况进行了仿真研究, 并对部分仿真数据加以试验验证。CFD仿真结果表明, 扭簧刚度对被动扑翼推进性能具有重要影响, 在二级海况下, 扭簧刚度为6 N·m·rad^-1时被动扑翼具有较高的推进效率和推进速度。CFD仿真数据与试验数据具有相同的趋势, CFD仿真模型可靠度较高, 对波浪滑翔器被动扑翼机构设计具有指导意义。

Abstract: The passive flapping foil mechanism of a wave glider is the key module that provides forward driving, and its propulsion efficiency directly affects the wave glider’s forward speed and position control accuracy. In this study, a complete analysis framework of the passive flapping foil propulsion efficiency was built, and a computational fluid dynamic(CFD) simulation model of the passive flapping foil propulsion motion is established. Simulation research on the passive flapping foil loaded with torsion spring under second-level sea state was conducted, and some simulation data were verified by experiments. The CFD simulation results show that the torsion spring stiffness has a significant impact on the propulsion performance of the passive flapping foil, and the passive flapping foil had a higher propulsion efficiency and speed when the torsion spring stiffness was 6 N·m·rad^-1 in the second-level sea state. This study shows that the CFD simulation and experimental data follow the same trend, and the reliability of the CFD simulation model is high, which has guiding significance for the design of the wave glider’s passive-flapping foil mechanism.
