At present, the traditional honeycomb structure mainly comprises a hexagon, a square, a triangle, a circle and the like, the bearing capacity is mainly based on the compression of different surfaces, but the coplanar bearing capacity is weaker. When the different-surface compression is carried out, the honeycomb shows obvious regular progressive folding deformation and stable energy absorption, but when the coplanar compression is carried out, the cell walls of the honeycomb cell rotate around the end points of the cell walls to cause cell collapse, the bearing capacity is lost, and the energy absorption effect is poor. Therefore, the conventional honeycomb structure can only play a role of one-way buffering, and is usually installed according to the different-plane direction of the honeycomb structure so as to ensure the maximization of the bearing capacity.
However, in practical application scenarios of the cellular structure buffer device, such as a front end bumper of an automobile, a crash-proof design of a bottom cabin of a helicopter, a design of a high-speed train anti-creeper, etc., the direction of an impact load borne by the cellular structure usually has a great uncertainty, which requires that the cellular structure has certain strength in a coplanar direction in addition to providing necessary different-plane bearing capacity. This is in contradiction to the poor coplanar carrying capability of conventional honeycomb structures.
Therefore, the existing honeycomb buffering and energy absorbing structure is lack of a design for resisting multidirectional impact buffering and energy absorbing, and is difficult to meet the bearing requirement under the condition that the multidirectional load direction is uncertain.
