One-way impact isolating device for satellite

Abstract

The invention discloses a one-way impact isolating device for a satellite. The one-way impact isolating device is mainly composed of a frame body, a cover plate, a bottom plate and two energy absorption material blocks. The cover plate is mounted on the frame body and is in surface contact with the frame body, a relative displacement section is formed inside the plate surface of the cover plate between the cover plate and the frame body, and thus an impact energy absorption action space exists in the direction. The bottom plate is mounted on the frame body, and the bottom plate and the cover plate are in surface contact. The energy absorption material blocks are contained into two enclosed spaces which are defined by the frame body, the cover plate and the bottom plate and are in close fit with the frame body and the cover plate. According to the one-way impact isolating device for the satellite, an impact-isolated object can be borne reliably and safely, the mounting rigidity, strength, position accuracy and the like of the impact-isolated object are guaranteed, meanwhile, impact transmission can be effectively isolated in one certain direction, it can be reliably guaranteed that the impact-isolated object has a sufficiently small impact environment, and the purpose that the impact-isolated object or an impact sensitive component can operate safely in an on-orbit mode for working is achieved.

Description

technical field

[0001] The invention relates to the field of aerospace technology, in particular to a one-way impact isolation device for satellites. Background technique

[0002] Generally, satellites use one-way impact isolation devices, because satellite deployment accessories (such as solar arrays, deployable antenna arrays, etc.) are generally designed with honeycomb damping parts for impact on pyrotechnics, which can reduce the impact in a certain direction, but cannot cover all directions. Therefore, it is necessary to design a one-way impact isolation device for satellites to isolate and absorb impacts in directions that cannot be covered by the deployment attachment itself. Moreover, the one-way impact isolation device adapts to the characteristics of the satellite such as smaller design space, lower weight, and mature space-flight materials. At the same time, the impact isolation device also needs to ensure the installation rigidity, strength and accuracy of the c...
