Variable Stiffness Actuation for Bioinspired Underwater Propulsion

研究项目：本项目旨在研究在水生推进器中嵌入可变刚度致动器（VSA）的使用，以确保在最大推进效率下持续运行。特别是，水生推进器使用脉冲射流推进的灵感来自鱿鱼，章鱼和水母。研究了附加质量、作动频率和涡流环三者之间的相互关系及其对推进器效率的影响。

Research project: This project aims to study the use of Variable Stiffness Actuators (VSA) embedded in aquatic propulsors to ensure persistent operation at maximum propulsive efficiency. In particular, aquatic propulsors using pulsed-jet propulsion inspired by squids, octopuses and jellyfishes are considered . The interconnections between added-mass, frequency of actuation and vortex rings are studied as well as their impacts on the efficiency of the propulsors.
