Abstract

The invention discloses a flexible bionic tail fin with embedded drive joints and multiple motion modes, relates to a tail fin and aims to solve the problems that according to an existing underwater bionic tail fin pushing device, structure is complex, maintenance and replacement costs are high, the motion mode is single, and the bionic effect is far from the natural actual fish swimming effect. The flexible bionic tail fin comprises a flexible bionic skin, an elastic clamping frame, a first piezoelectric fiber composite drive joint and N second piezoelectric fiber composite drive joints. The elastic clamping frame, the first piezoelectric fiber composite drive joint and the N second piezoelectric fiber composite drive joints are embedded in the flexible bionic skin, the first piezoelectric fiber composite drive joint and the N second piezoelectric fiber composite drive joints are detachably connected to the elastic clamping frame respectively, and the first piezoelectric fiber composite drive joint is arranged in the middle of the flexible bionic skin axially and horizontally. The flexible bionic tail fin belongs to the field of fish-simulation underwater pushing devices.

Description

technical field [0001] The invention relates to a caudal fin, in particular to a bionic caudal fin with flexible multi-movement modes, which belongs to the field of fish-like underwater propulsion devices. Background technique [0002] Most of the traditional underwater thrusters use the propeller as the drive unit. Practice has proved that there are many inevitable problems in this method, such as heavy weight, large volume, high energy consumption, low efficiency, poor reliability, poor maneuverability, and Accompanied by large noise and wake vortex, it has a certain negative impact on the survival of marine organisms and the environment. These shortcomings limit its application in the field of underwater vehicles to a certain extent. In the past 10 years, with the gradual acceleration of the pace of human use and development of the ocean, bionic underwater vehicles have also been gradually developed. Among this type of vehicles, fish-like robots are the most popular. ...
