The invention discloses a novel energy absorption box based on zero-Poisson-ratio pressure-torsion metamaterial filling, and relates to the technical field of mechanical metamaterials. The energy absorption box comprises a cylindrical thin-wall shell, a front end plate fixedly connected with the front portion of the cylindrical thin-wall shell, a rear end plate arranged on the rear portion of the cylindrical thin-wall shell, and a 3D accordion type zero-Poisson-ratio compression-torsion metamaterial energy absorption filling body installed in the cylindrical thin-wall shell. The novel energy absorption box based on zero-Poisson-ratio pressure-torsion metamaterial filling has excellent energy absorption capacity and good energy absorption stability; the design of structural parameters can be correspondingly adjusted according to actual working condition requirements; and the method has rich parameter design diversity.
