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. [0003] With its excellent mechanical properties, intelligent deformation structures with controllable buckling modes have been successfully applied in automotive, aerospace and other fields. At present, there are many kinds of modal control methods for smart deformable str...

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.
