Problems solved by technology

[0003] 1. The artificial muscle realizes radial expansion and contraction by the gas and hydraulic pressure acting on the end face of the tubular artificial muscle. When the diameter is very small (such as 0.3-1 mm in the invention, minus the thickness of the tube wall, the effective diameter should be smaller) , the pressure acting on the end surface is bound to be very small, while the pressure acting on the side surface is much larger than that on the end surface. To make the tubular artificial muscle stretch effectively, only increase the pressure. The higher the pressure, the greater the pressure, so it is difficult to Guarantee the sealing of the tubular artificial muscle wall
[0004] 2. When the pressure is high, it is difficult to ensure the sealing between the pump, interface, hose and control valve, and this type of sealant is expensive

Embodiment Construction

[0015] see figure 1 with figure 2 , the artificial muscle is composed of a plurality of single-bundle artificial muscle fibers as basic constituent units. A single bundle of artificial muscle fibers is composed of a double helix coil 1, elastic glue 2, and magnetorheological fluid micelles 3. The appearance and interior of the double helix coil 1 are covered and filled with elastic glue 2. During production, the double helix coil 1 is sprayed with elastic glue Liquid, the elastic glue gradually solidifies when it encounters air, and slowly rotates the helical coil 1 during the curing process, so that the elastic glue 2 is evenly covered on it. The elastic glue 2 is filled with magnetorheological fluid micelles 3, and the magnetorheological fluid micelles 3 are composed of magnetorheological fluid carriers and polarizable magnetic particles. The magnetorheological fluid carrier is silicon oil, and the polarizable magnetic particles are pure iron powder or oxide powder. The ...

Abstract

An artificial muscle is composed of many artificial muscle fibre bunches. A single artificial muscle fibre bunch consists of double helical coils, elastic colloid and magnetic rheopectic liquid microball composed of magnetic rheopectic liquid carrier and polarizable magnetic particles. Its advantages are use of magnetic rheopectic effect to implement muscular contraction with strong contraction force, light weight and simple structure.

Description

technical field [0001] The invention belongs to the technical field of robot manufacturing and dynamic motion simulation, and in particular relates to an artificial muscle. technical background [0002] Artificial muscles can be widely used in robots, manipulators, prosthetics, bionic toys, props and other fields. There are many ways in the design of artificial muscles in the prior art. Chinese patent 97110134.5 discloses an artificial tubular muscle and its application. The specific design is a tubular structure made of polymer elastic material and fibers, and the fibers are evenly distributed on the tube wall. In this method, one end of the tubular structure is closed, and the other end is connected to the pump through the interface, hose, and control valve. The tubular muscle is driven by the pump to expand and contract along the axial direction of the tube without lateral expansion. The artificial muscle has a certain muscle contraction function, but has the following t...
