Active deformation honeycomb structure skin based on pneumatic muscle

Abstract

The invention discloses active deformation honeycomb structure skin based on a pneumatic muscle, belongs to the field of deformation aircrafts, and aims to solve the problem of poor deformation performance of the conventional skin structure. The active deformation honeycomb structure skin based on the pneumatic muscle comprises a silicon rubber material, the pneumatic muscle, a spring and a zero-Poisson-ratio honeycomb structure, wherein the outer surface of the pneumatic muscle is sleeved with the spring; the pneumatic muscle sleeved with the spring is inserted into the zero-Poisson-ratio honeycomb structure; the pneumatic muscle passes through a rib piece of each honeycomb unit in the zero-Poisson-ratio honeycomb structure; two ends of pneumatic muscle are fixedly arranged on boundary rib pieces of the zero-Poisson-ratio honeycomb structure respectively; the silicon rubber material is attached to the surface of the zero-Poisson-ratio honeycomb structure to serve as a skin material. The active deformation honeycomb structure skin based on the pneumatic muscle disclosed by the invention has the advantages of high carrying capability along a vertical direction, large deformation being up to 30 to 40 percent in a deformation direction, coordinated deformation of a honeycomb and the pneumatic muscle, and easiness in control.

Description

technical field [0001] The invention belongs to the field of deformable aircraft, and in particular relates to a deformable skin structure for deformable aircraft. Background technique [0002] The honeycomb structure has excellent geometrical mechanical properties, excellent compression resistance, bending resistance and ultra-light structural characteristics, so it is widely used in material science. Compared with solid materials of the same type, honeycomb materials have the highest strength-to-weight ratio and stiffness-to-weight ratio of any known material. Honeycomb structure panels have many superior properties. From a mechanical point of view, compared with other structures, the closed hexagonal equilateral honeycomb structure can obtain the maximum force with the least material. When the honeycomb structure panel is subjected to a load perpendicular to the panel surface, Its bending stiffness is almost the same as that of a solid plate of the same material and thic...
