A reusable passive energy-absorbing pull/compression bi-directional buffer

Abstract

The invention discloses a driven energy absorbing pulling / pressing both-way buffer capable of being repeatedly used, and belongs to the technical field of spaceflight equipment. The device is mainly composed of four parts including an outer barrel assembly, a middle barrel assembly, an inner barrel assembly and a pull barrel assembly, wherein the middle barrel assembly is coaxially arranged in theouter barrel assembly, the inner barrel assembly is coaxially arranged in the middle barrel assembly, and the pull barrel assembly is coaxially arranged on the periphery of the connecting position ofthe outer barrel assembly and the middle barrel assembly. According to the device, through an innovatively-designed aluminum honeycomb resetting mechanism, a mechanical spring resetting device and aratchet one-way locking device are combined with the pulling / pressing both-way buffer based on aluminum honeycomb crushing energy absorbing materials, and the advantages that a traditional driven energy absorbing both-way buffer is simple in structure, small in mass and high in reliability are sufficiently inherited; and the traditional pulling / pressing both-way buffer can be repeatedly used and can be used for repeatedly-used soft landing devices needed for multi-target deep space exploration tasks in future.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment, and as an auxiliary buffer pillar on a reusable star surface soft landing device, specifically refers to a reusable passive energy-absorbing pull / press two-way buffer. Background technique [0002] With the advancement of technology, in the future deep space exploration missions, one launch will complete the multi-point soft landing detection of the same target star or the soft landing detection of multiple target stars, which is very important for the development of reusable soft landing. The device puts forward requirements to reduce the comprehensive cost of a single detection mission including launch while meeting the increasingly frequent needs of deep space exploration. [0003] In the soft landing device for star surface exploration, the leg-foot landing buffer mechanism is a key component, and the main / auxiliary buffer pillar is the core component of the landing buffer mechani...
