  • Network structure, shock-absorbing body, vehicle, and design method of network structure
    Patent number: 10974770
    Abstract: A network structure is formed in a three-dimensional mesh shape in which a plurality of polyhedron frames are arranged. Each polyhedron frame is formed by a plurality of apexes disposed in a three-dimensional space and connecting members for connecting the apexes. The plurality of polyhedron frames are regularly arranged so that the polyhedron frames are displaced at a constant degree when a constant load is applied.
