Three-way shock isolation device for satellite

Abstract

The invention discloses a three-way shock isolation device for a satellite. The three-way shock isolation device mainly comprises a frame body, a cover plate, a bottom plate and four energy absorption material blocks, wherein the cover plate is mounted on the frame body, and is in surface contact with the frame body; the cover plate and the frame body relatively displace on the surface of the cover plate, so that a shock energy absorption action space is formed in the direction; the bottom plate is mounted on the frame body, and is not in contact with the cover plate; the four energy absorption material blocks are respectively mounted in four independent spaces formed by the frame body, the cover plate and the bottom plate, and are in tight fit with the frame body, the bottom plate and the cover plate. The three-way shock isolation device can bear objects subjected to shock isolation reliably and safely, ensures the mounting rigidity, the strength, the position precision and the like of the objects subjected to shock isolation, meanwhile, effectively isolates the shock transmission in three directions, ensures that the objects subjected to shock isolation are in a small enough shock environment reliably, and achieves the purpose that the objects subjected to shock isolation or shock sensitive parts are in on-track operation safely.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a three-way impact isolation device for satellites. Background technique [0002] Generally, satellites use a three-way impact isolation device, because satellite deployment accessories (such as solar arrays, deployable antenna arrays, etc.) are generally designed with honeycomb damping parts for impact on explosives, which can reduce the impact in a certain direction, but cannot cover all directions. Therefore, it is necessary to design a three-way impact isolation device for satellites to isolate and absorb impacts in directions that cannot be covered by the deployment attachment itself. Moreover, the three-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 o...

Problems solved by technology

Since there is no mature technology for three-way impact isolation devices for this type of satellite at this stage, and there are many impact-sensitive components on the satellite, they are easily damaged due to impact
