Description
Technical Field
The invention belongs to the field of adjustable torsion fiber driving, and particularly relates to an adjustable torsion fiber driving test bed and a working method thereof.
Background
The artificial muscle is studied in order to simulate the human force-exerting form and show the muscle superiority, and the muscle-like form factor of all the natural muscles with ideal properties is shown. More sophisticated techniques now include shape memory alloy actuators and shape memory polymer actuators. These materials shrink and expand in their cross-section by electrical, optical or chemical activation. Since these materials tend to exhibit small strain deformations, large deformations are typically achieved by parallel plate designs. Larger memory polymers have achieved the use of stacked designs to increase strain deformation, but these also lead to the emergence of some of the more bulky actuators. It has recently been found that by continually twisting certain twisted fibers to an extreme, until they form a coil, they can withstand forces and deformations even beyond the skeletal muscles of the human body, while maintaining a cord form. These "supercontinuum" actuators constructed from certain twisted fibers are capable of producing large power-to-weight ratios with high repeatable shrinkage strains. Research teams have shown that this can also be achieved by twisting commercially available fibers such as fish line, sewing line, etc., thereby providing an opportunity for very low cost, readily available artificial muscles. The test bed is utilized to simplify the manufacturing process of the artificial muscle and achieve a more standard winding structure.
