Abstract

The invention discloses a bionic-based cavitation jet test system and a debugging method thereof, comprising a bionic device, a high-energy generating device, an underwater pressure test module and a high-speed photography module. The bionic device simulates the rapid closure of the pincers to generate cavitation jets, and the high-energy generator provides the power to simulate the rapid closure of the pincers, and adjusts the high-energy generator to drive the simulated rapid closure of the pincers to generate cavitation jets, and records the cavitation jets through the underwater pressure test module The size of the pressure pulse generated by the bursting of the bubbles, the high-speed camera module records the closing process of the simulated pincers and the process of bubble generation, growth and collapse. The present invention overcomes the difficult problem that it is difficult to study the mechanism of the cavitation jet of the pistil shrimp through the test method of the bionic device on the basis of investigating relevant materials at home and abroad, and invents a high-energy generation device test system, which realizes the test of the bionic device through the prickly shrimp pinch To study the mechanism of the cavitation jet in the claw of the gun shrimp.

Description

technical field [0001] The invention relates to the field of bionic test systems, in particular to a bionic design-based cavitation jet test system and a debugging method thereof. Background technique [0002] So far, the functions of organisms in nature are much superior to any artificially manufactured machinery, such as the process of quickly closing the claws of the gun shrimp for predation. Bionics is people's research on the working principles of the structure and function of organisms, and based on these working principles, they create tools that are beneficial to human production, learning and life. [0003] Gun shrimp, also known as drum shrimp, is a tropical marine creature. The body length of the gun shrimp is about 5cm, and it has a pair of claws of different sizes, and the length of the big claw is about half of the body length. When receiving external stimuli, the gun shrimp quickly closes its pincers at a speed of about 3500 rad / s, condenses a high-speed jet...

AI Technical Summary

Problems solved by technology

In the early stage, most of the live gun shrimps were observed and measured by high-speed photography and hydrophones. Later, relevant scholars obtained the 3D model of the gun shrimp through CT scanning of the claws of the gun shrimp, and studied the cavitation jet phenomenon of the gun shrimp through bionic experiments. However, due to the The closing speed of the claw can reach up to 5000rad / s. It is difficult for the current driving device to achieve this closing speed. It is difficult to design a high-energy driving device for the claw of the gun shrimp.
