Abstract

The invention relates to a novel cellular honeycomb energy absorbing buffering device. The novel cellular honeycomb energy absorbing buffering device comprises a shell and an aluminum honeycomb structure; the aluminum honeycomb structure is placed in the shell and connected with the shell; the shell comprises a side plate, an upper skin and a lower skin; the edge of the upper skin is connected with the upper surface of the side plate; the edge of the lower skin is connected with the lower surface of the side plate; the aluminum honeycomb structure is an array structure consisting of a plurality of aluminum honeycomb cellular structures; each aluminum honeycomb cellular structure comprises a hollow regular hexahedron aluminum sheet, a hollow cuboid aluminum sheet and two V-shaped aluminum sheets, the hollow regular hexahedron aluminum sheet forms the external contour of each aluminum honeycomb cellular structure; the hollow cuboid aluminum sheet is embedded in each hollow regular hexahedron aluminum sheet, and the two V-shaped aluminum sheets are connected between the hollow regular hexahedron aluminum sheet and the hollow cuboid aluminum sheet; and the plurality of aluminum honeycomb cellular structures are interlaced with each other; and therefore, the novel cellular honeycomb energy absorbing buffering device can bear orthogonal three axis stress and can possess a certain bearing and energy absorbing ability in multiple directions and at any angle.

Description

technical field [0001] The invention relates to the technical field of structural buffering and energy absorption, in particular to a novel cellular honeycomb energy-absorbing buffering device. Background technique [0002] Helicopters and UAVs are widely used in military, civil, consumer and other fields due to their unique vertical take-off and landing, hovering performance, good low-speed characteristics, and safe landing due to rotation. However, helicopters and UAVs have low flying heights. Before an abnormal touchdown, the driver or UAV operator has a short reaction time to select the maneuvering action, and is prone to damage when falling to the ground. Therefore, its body structure lacks anti-crash design or crashworthiness design. [0003] At present, the fuselage mainly relies on the plastic deformation or destruction of the buffer structure to absorb energy, and limits the impact load acting on the occupant's body within an acceptable range to play a role in crash...
