Research on Biomimetic Fin Propulsor Compound Driven by Motor and Intelligent Material
摘要
Abstract
A motor intelligent material compound drive biomimetic propulsor was proposed. Firstly, the mechanical structure and control circuit of biomimetic fin propulsor was analyzed. Secondly, the output torque of motor was calculated according to the force of fin ray and structure endured during movement. Also, the analysis of thermodynamics on shape memory alloy ( SMA) wire based on fin ray bending was established. Finally, the variety of averaged propulsion velocity and averaged thrust with frequency was tested under the condition that the fin ray amplitude gradually increased from roots to ends as well as the amplitude was fairly constant. The results indicate that the biomimetic fin is able to achieve undulating motion, oscillating motion and complex three-dimensional flexible motion, which also satisfies the requirements of cruising, turning, stability control.关键词
