Bionic fishtail structure driven by eccentric wheel

Abstract

The invention provides a bionic fishtail structure driven by an eccentric wheel. The bionic fishtail structure comprises a deep caudal peduncle, a fishtail, the eccentric wheel and a micro-motor, wherein the deep caudal peduncle and the fishtail are prepared from a fiber reinforced composite material; the micro-motor and the eccentric wheel are contained in the deep caudal peduncle, the motor drives the eccentric wheel to move, and a tail fin of the structure is enabled to move. The bionic fishtail structure can realize complicated motion of fish such as Spanish mackerels, tunas and the like adopting a BCF (body-caudal fin flapping) propulsion mode, and has the advantages of high efficiency, low cost, light weight, simple structure and the like.

Description

technical field

[0001] The invention relates to a bionic structure, in particular to a bionic fishtail structure driven by an eccentric wheel, which belongs to the field of bionics. Background technique

[0002] With the continuous progress and development of underwater bionics, robotics, new materials and other disciplines, as well as the increasing demand for offshore development, bionic fish that resemble fish has become a research hotspot in the field of machinery. Bionic fish can explore and in-depth study of seafloor animal and plant resources, and is widely used in underwater environment detection, port monitoring, search and rescue operations, humanitarian demining, coastal security, fishery management, anti-terrorism operations and military operations, etc. The research on the propulsion mode of fish has become the basis of bionic fish. The propulsion mode of fish is divided into jet type, BCF propulsion mode (caudal fin propulsion), MPF propulsion mode (pectoral fi...
