Abstract

The invention relates to an anti-shock mount based on a chiral structure, in particular to an anti-shock mount suitable for explosion buffering and energy absorption of pyrotechnic devices of spacecraft, and belongs to the technical field of explosion buffering and energy absorption of pyrotechnic devices of spacecraft. The chiral structural unit is arranged on the structural body of the mounting seat, and also includes a flange fixedly installed with the pyrotechnic device and the docking section of the rocket. The mount adopts a chiral structure design, which has a simple design structure and is easy to install. It is used to connect the pyrotechnic separation device with a large impact load and the satellite body structure; according to the requirements for buffering and energy absorption, the structural configuration direction, The geometric design parameters of nodes and ligaments are adjusted to effectively suppress the impact load of concern and ensure the reliable operation of precision spaceborne equipment and structures.

Description

technical field [0001] The invention relates to an anti-shock mount based on a chiral structure, in particular to an anti-shock mount suitable for explosion buffering and energy absorption of pyrotechnic devices of spacecraft, and belongs to the technical field of explosion buffering and energy absorption of pyrotechnic devices of spacecraft. Background technique [0002] With the rapid development of new spacecraft technology, the structure of spacecraft presents the characteristics of "big, light, and soft". This development trend has led to an increasing risk of in-orbit spacecraft being impacted by the explosion of pyrotechnic devices. The traditional satellite pyrotechnic device mounting seat design often only has a load-carrying capacity, but cannot effectively buffer the impact load generated at the moment of the pyrotechnic device explosion. [0003] With the development of modern aerospace technology, the sensitivity of spaceborne equipment is getting higher and hig...
