Structural Design/Manufacturing and Cavitation Efficiency Calculation of the Bio-Inspired Snapping-Claw Apparatus

The snapping shrimp's unique claw structure enables it to produce high-energy cavitation bubbles instantaneously during hunting, inspiring the development of a high-efficiency cavitation generator. This paper simplifies the structure of the shrimp's claw to design a new bionic snapping-claw apparatus, and uses a torsion spring as its driving mechanism. The proper spring was selected by solving the relevant established kinetic equations, and the bionic snapping-claw apparatus was manufactured using a five-axis high-speed processing center. Additionally, the principles of energy conservation and equivalent thought were applied to calculate the cavitation efficiency of the bionic apparatus, revealing an impressive efficiency of 25.6%, outperforming most existing cavitation generating devices.
