摘　　要：在Bose变形模式及悬臂梁受力变形分析的基础上,提出了摆动水翼新的柔性变形模式,推导出弦向变形方程,给出了摆动水翼变形运动描述及动网格处理技术,利用数值方法研究了柔性变形模式、柔度系数、弦向变形长度等参数对柔性水翼推进特性的影响,指出了摆动水翼高推进性能对应的柔性模式与变形参数。On the basis of Bose＇s mode and analysis of cantilever beam, the new chordwise deflection modes are proposed.The deflection equations are deduced and description of the flapping foil and technology of dynamic meshes are presented, too. The influence of various parameters, such as deflection modes, flexible coefficient and deflection length,on the propulsion performance of flexible flapping foil is numerically researched. In addition, the deflection mode and relevant parameters for the optimum propulsion performance are pointed out.
