Abstract: An adjustable circular tube energy absorption/storage mechanism based on a paper-cut structure is disclosed according to the present application, which belongs to the technical field of advanced intelligent structure. The mechanism is based on the conventional circular tube and obtained by partially cutting the circular tube. The direction of the slits is along the axial direction of the circular tube. Multiple circular tubes may be arrayed in a specific way according to the actual application requirements. When the circular tube is subjected to axial impact force, the cutting section of the circular tube may deform in a specific direction, the circular tube realizes structural energy absorption and energy storage through local buckling deformation, and after the external force is removed, the circular tube recovers from the deformation and releases stored energy.
