气动软体致动器驱动的仿生鱼尾设计及试验
Design and experiment of bionic fish tail driven by soft pneumatic actuator
摘要
Abstract
To explore the C-starting behavior of fish,a single-jointed bionic fish tail driven by a pneumatic fiber-constrained soft body actuator is designed using the tail of a tuna with a crescent-shaped caudal fin as a bionic model.A comparison of the expansion and contraction performance between fiber-constrained soft actuator and non-fiber constrained soft actuator is provided.With the help of digital particle image velocimetry,the flow field visualization test of the C-starting process of the bionic fish tail driven by different air pressures is conducted.The contributing factors of the propulsive capability are quantitatively analyzed by vortex ring impulse calculation.Results show the vortex ring impulse generated by the bionic fish tail during C-start increases with the decrease of the oscillation period and is affected by the oscillation angle in the study range.Meanwhile,the vortex ring impulse increases with the rise of the output air pressure before the optimal oscillation angle is reached.Then,it fluctuates and tends to be stabilized after the optimal oscillation angle is exceeded.关键词
