Intelligent structure with controllable deformation pattern and deformation method thereof

Abstract

The invention provides an intelligent structure with a controllable deformation pattern and a deformation method thereof. The intelligent structure comprises a fixing block, a deformable structure, asize-variable reinforcing block and a sliding block. The fixing block is used for being fixedly connected with the deformable structure. The deformable structure is provided with a deformable body, and one end of the deformable structure is connected to the fixing block. The size-variable reinforcing block is composed of at least two reinforcing block bodies with variable sectional sizes or two ormore reinforcing block bodies forming the size change, and the reinforcing block bodies are sequentially arranged on the deformable structure in the extrusion direction. The sliding block is connected with the other end of the deformable structure, and the deformation shape of the deformable structure is controlled by adjusting the displacement of the sliding block. The intelligent structure is purely mechanical, the drive mode is simple, structures with different shapes can be prepared without an additional die or other blocking devices, and the intelligent structure has the advantages thatthe process is simple, the shape is adjustable, and the configuration is stable, and can be widely used for shape control systems such as automobiles, aerospace, medical robots and ocean carriers.

Description

technical field [0001] The invention belongs to the technical field of intelligent materials and structures, and in particular relates to an intelligent structure with a controllable deformation mode and a deformation method thereof. Background technique [0002] The deformation mode controllable structure can adjust its own deformation shape through single or multiple control parameters to achieve specific functional requirements, such as underwater drag reduction, vibration and noise reduction, and adjustable stiffness. This type of structural flexible manufacturing system has broad application prospects in variant structures in many fields such as automobiles, aerospace, ships, and medical treatment.

AI Technical Summary

Problems solved by technology

[0004] Although these control methods can effectively ensure the adjustment of the deformation of the structure, they can only realize the adjustment of the deformation amount under a single shape. For example, after turning the structure into an arch, only the height of the arch can be changed, and it cannot be changed into a double hump or other appearance

In order to achieve different shape changes, the general method is to increase the driving structure and deformation constraints, which greatly increases the complexity of the manufacturing process and increases the cost

[0005] In summary, the existing deformable structures have the problems of complex driving methods, single deformation modes, and high control costs. It is urgent to design a new type of deformable structure to meet the application requirements of many industrial fields.
