摘要/Abstract

摘要： 为了提升振荡翼的捕能性能,该文采用田口试验和CFD相结合的方法,对决定振荡翼捕能性能的5个特征参数进行优化。结果表明：振荡翼的特征参数对其捕能性能具有重要影响,最优和最差参数组合下振荡翼捕能效率相差137.84%。俯仰中心位置对振荡翼捕能效率影响最大,在试验样机设计中应优先考虑;所研究的5个特征参数对振荡翼捕能性能的影响程度依次为：x_p/c>θ₀>翼型相对厚度>h₀/c>f^*。通过对不同参数组合振荡翼的流场分析发现,特征参数优化的振荡翼产生的涡流始终吸附在翼型表面,从而使振荡翼获得较好的升力特性,进而在升沉运动中捕获更多的能量。

Abstract: In order to improve the energy capture performance of the oscillating wing, the Taguchi test and CFD method are used to optimize and analyze the five characteristic parameters that determine the energy capture performance of the oscillating wing. The results show that the characteristic parameters of the oscillating wing have an important effect on its energy capture performance. The difference of energy capture efficiency of the oscillating wing between the optimal and the worst parameters is 137.84%. The position of the pitching center has the greatest effect on the energy capture efficiency of the oscillating wing and should be given priority in the design of the experimental prototype. With respect to the five characteristic parameters studied, their effect degree on the energy capture performance of the oscillating wing is sortedfromthelargesttothesmallest：x_p/c,θ₀, the relative thickness of airfoil, h₀/c, f ^*. By analyzing the flow field of the oscillating wing with different parameter combinations, it is found that the vortex generated by the optimized oscillating wing is always attached on the surface of the airfoil, so that the oscillating wing can obtain better lift characteristics and capture more energy in the heaving motion.
