Problems solved by technology

However, this kind of artificial dolphin skin is still at a relatively low level in imitating the special and complex structure of the dolphin skin biological prototype, especially in the imitation of the dynamic deformation structure of the dolphin papillae, which is only replaced by a simple rubber nipple. There is obviously still a lot of room for improvement in terms of bionics and functional bionics

Abstract

The invention relates to the technical field of engineering bionics, in particular to bionic dolphin skin based on electroactive polymer artificial muscles. The bionic dolphin skin comprises a supporting base, a hardened conducting layer, a flexible resin layer, a flexible conducting layer, a smooth rubber layer and an artificial muscle stretching and contraction unit, wherein the artificial muscle stretching and contraction unit comprises a certain number of electroactive polymer artificial muscle bundles and stretching heads. Compared with the prior art, the electroactive polymer artificial muscles are used for simulating elastic mastoids in a dolphin skin structure, functions which are shown when the electroactive polymer artificial muscles are powered on and contract and very similar to those of biological muscles are used for simulating biological functions of the elastic mastoids in the dolphin skin structure, the flexible working mechanism of the bionic dolphin skin is more flexible and controllable, and beneficial examples are provided for engineering bionics technologies, particularly, bionic anti-drag surface manufacturing technologies in terms of structural and functional bionics.

Description

technical field [0001] The invention relates to a bionic dolphin skin, in particular to a bionic dolphin skin based on an electroactive polymer artificial muscle, and belongs to the technical field of engineering bionics. Background technique [0002] Effectively reducing the surface resistance of aircraft to improve speed, maneuverability, endurance and fuel efficiency is of great significance to national economy and national defense security. High-speed underwater organisms such as dolphins, sharks, and tuna undoubtedly provide humans with extremely valuable engineering bionic models. The targeted development of low-resistance, high-efficiency bionic drag-reducing skin has become a current research hotspot and difficulty. [0003] Dolphins are the champions of swimming in the ocean, with a speed of 70-100 kilometers per hour. As early as 1936, British scientist Gray discovered that the swimming speed of dolphins had far exceeded the limit of their muscle strength, and the...
