Description

technical field [0001] The invention relates to the technical field of material structures, in particular to a chiral multicellular structural unit, an assembly and an intelligent construction method. Background technique [0002] Chiral cellular structures are an emerging field of research in recent years, and have attracted much attention due to their novel and unique physical and mechanical properties that cannot be achieved by general centrosymmetric cellular structures, such as negative Poisson's ratio effect and dual-modulus properties. Wait. It is precisely because of the excellent properties of the chiral cellular structure and the macro and micro scales it covers that it has broad application prospects. For example, chiral honeycomb structures used in the field of shock-resistant buffers, chiral phononic crystal materials used in wave regulation, programmable chiral soft materials used in the field of smart responsive structures, etc. [0003] However, most of the...

Problems solved by technology

The units of these chiral multicellular structures often have the same size. Even if such units have different sizes, it is only a simple copy of the number of units, without multi-level characteristics, and it is impossible to carry out more refined functional design of the chiral structure.

At the same time, most of the existing chiral multicellular ligaments are rod or beam structures, which cannot withstand large compressive loads, which limits their energy absorption capabilities.

[0004] In summary, the research on chiral multicellular structures is still limited, and there is still a lot of room for design and functional improvement, especially the multilevel chiral multicellular structures and their intelligent construction methods are still lacking.
