摘　　要：采用重叠网格技术对采取非正弦曲线运动的拍动翼的推进效率进行数值模拟研究。系统地分析β值、俯仰运动幅值和特哈尔数对拍动翼推进效率的影响,并将非正弦曲线运动的拍动翼推进结果与标准正弦曲线运动的拍动翼推进结果相对比,为后续仿生潜器的设计提供技术依据和理论指导。数值模拟结果表明,β值对拍动翼的推进性能具有重要影响。The numerical simulation of the non-sinusoidal flapping foil propulsion is performed with overlapping grid method to investigate the propulsive efficiency. The influences of motion parameters and β values on the propulsive performance are systematically investigated. The results are compared with those of typical sinusoidal flapping foil designs. It is proved that β values are of the vital factors to the propulsive performance of flapping foil.
