Abstract

The invention relates to a multi-directional bearing honeycomb structure buffer energy-absorbing device, comprising: a housing and a honeycomb filling structure; the honeycomb filling structure is installed inside the housing and connected to the housing; the honeycomb filling structure is a plurality of honeycomb filling structures An array structure composed of cells; the honeycomb cell includes a hollow regular hexahedron sheet, a hollow cuboid rectangular sheet and two intersecting single-sided sheets; the hollow regular hexahedron sheet constitutes the outer contour of the honeycomb cell, The hollow cuboid rectangular thin plate is embedded in the hollow regular hexahedron thin plate; the two single-sided thin plates are embedded in the hollow rectangular rectangular thin plate in a diagonal form. The present invention has a higher longitudinal bearing capacity, and has a certain load-bearing and energy-absorbing capacity for multi-directional and arbitrary angle loads. Compared with the traditional honeycomb structure, the multi-directional bearing capacity is improved, the applicable environment is wider, and the buffering and energy-absorbing effect is better. .

Description

technical field [0001] The invention belongs to the technical field of structural buffering and energy-absorbing, and in particular relates to a multi-directional load-carrying honeycomb structure buffering and energy-absorbing device. Background technique [0002] Helicopters and unmanned aerial vehicles are widely used in military, civil and transportation fields due to their unique vertical take-off and landing, hovering performance and good maneuverability. Short, so the crash probability is greatly increased, so the body structure needs anti-crash design or crashworthy design. [0003] At present, the energy absorption of fuselage fall buffering mainly relies on the plastic deformation or destruction of related buffer devices to absorb energy, and limits the impact load acting on the occupant's body within an acceptable range to play a role in crashworthiness. The honeycomb structure has the advantages of small density, low stiffness, large compression deformation, con...
