The invention relates to the field of
engineering bionic technology, in particular to bionic
sharkskin making use of a
shape memory alloy artificial muscle longitudinally-injected drag
reducer. The bionic
sharkskin making use of the
shape memory alloy artificial muscle longitudinally-injected drag
reducer comprises a supporting base, a hardened conductive layer I,
artificial muscle flexible units, a hardened conductive layer II, a shark scale
imitation skin layer and a drag
reducer longitudinal
injection device, wherein each artificial
muscle flexible unit comprises a
shape memory alloy artificial
muscle spring, a pulling head, a two-section
electric heating rod and a connection conductive wire, and each shape memory
alloy artificial
muscle spring has a certain amount of supporting strength. Compared with the prior art, the bionic
sharkskin making use of the shape memory
alloy artificial muscle longitudinally-injected drag reducer has the advantages that by the adoption of the design of shape memory
alloy artificial muscle, a micro
mucus secreting mechanism of the sharkskin is simulated by means of the unique material characteristic that the double-trip
memory effect is presented under the driving of transformation temperature of the shape memory alloy artificial muscle, the working mode and control method of injecting a micro amount of the drag reducer are more sensitive, controllable and reliable compared with existing means, service life is guaranteed effectively, and a beneficial example is provided for the
engineering bionic technology, especially the bionic drag reduction
skin manufacturing technology, in the aspect of
structure and function bionics.
