This paper studies the effect of the head swing motion on the fishlike robot swimming performance numerically. Two critical parameters are employed in describing the kinematics of the head swing： the leading edge amplitude of the head and the trailing edge amplitude of the head. Three-dimensional Navier-Stokes equations are used to compute the viscous flow over the robot. The user-defined functions and the dynamic mesh technology are used to simulate the fishlike swimming with the head swing motion The results reveal that it is of great benefit for the fish to improve the thrust and also the propulsive efficiency by increasing the two amplitudes properly. Superior hydrodynamic performance can be achieved at the leading edge amplitudes of 0.05L （ L is the fish length） and the trailing edge amplitudes of 0.08L. The unsteady flow fields clearly indicate the evolution process of the flow structures along the swimming fish. Thrust-indicative flow structures with two pairs of pressure cores in a uniform mode are generated in the superior performance case with an appropriate head swing, rather than with one pair of pressure cores in the case of no head swing. The findings suggest that the swimming biological device design may improve its hydrodynamic performance through the head swing motion.

应用溶解-铸膜法制备聚乙烯醇(PVA)-KOH-H2O碱性凝胶聚合物电解质膜。用交流阻抗测试电解质膜离子电导率,结果表明随KOH含量增加,电解质膜的电导率先增后减,当m(PVA):m(KOH)=3:4.5时(质量比,下同),室温电导率达到最大值,为4.63×10-2S/cm。聚合物电解质膜的电导率随温度的变化基本符合Arrhenius方程。加入KOH后,PVA结构从晶态向非晶态转变,结晶度降低,热稳定性提高。循环伏安和DSC热分析显示该聚合物电解质膜具有很好的电化学稳定性和热稳定性。有望应用于碱性二次电池。
