The invention provides a three-dimensional metamaterial functional component and a manufacturing method thereof.The functional component comprises a plurality of three-dimensional metamaterial cell elements which are detachably connected, each three-dimensional metamaterial cell element is composed of at least one two-dimensional metamaterial unit, and each two-dimensional metamaterial unit comprises a plurality of centrosymmetric two-dimensional metamaterial basic units; and the three-dimensional metamaterial cell elements are arranged in a space array mode. The two-dimensional metamaterial unit comprises a rigid metamaterial unit SPi, a flexible metamaterial unit SQi, a negative Poisson's ratio metamaterial unit SZi and a torsion metamaterial unit STi; different two-dimensional metamaterial units are selected and assembled into three-dimensional metamaterial cell elements with different topological structures and mechanical properties, and designability of structural deformation of the three-dimensional metamaterial cell elements in multiple directions under the action of loads is achieved. The two-dimensional metamaterial basic unit is simple in structure, manufacturing methods such as additive manufacturing and laser cutting are adopted, mass manufacturing can be effectively achieved, the manufacturing cost is reduced, and the manufacturing efficiency is improved.

The invention provides a large steel cylinder structure deformation control device and method. The large steel cylinder structure deformation control device comprises a supporting panel, a supporting web and an adjusting device installed on the supporting web. One of the outer peripheral edge and the inner peripheral edge of the supporting web is a supporting edge used for being in contact fit with the inner wall or the outer wall of a large steel cylinder structure, the other edge is a non-supporting edge, and the supporting panel is fixed to the non-supporting edge side of the supporting web; and the supporting panel and the supporting web are both non-closed annular pieces. The large steel cylinder structure deformation control device is provided with the supporting panel, the supporting panel and the supporting web are fixedly connected, the supporting panel and the supporting web are the non-closed annular pieces, supporting of the deformation control device and the inner wall or the outer wall of the steel cylinder is adjusted through the adjusting device, and the steel cylinder is kept in roundness and not prone to deformation; the construction space can be reserved to the maximum extent through the annular supporting panel; and the problem that a temporary supporting piece is adopted or a spider web support is installed is solved, and labor intensity is lowered.
