Abstract

The invention relates to satellite mechanical experiment equipment, in particular discloses a clamping device in the vibration distressing of a satellite mechanical experiment pressure ring, comprising a vibration distressing clamp (1) with counterbores (6) and screw holes (5). The counterbores (6) are used for connecting a vibration table, the screw holes (5) are used for connecting a vibration distressing fixed block (2) and a vibration distressing sliding block (3), the pressure ring is radially arranged and located between the vibration distressing fixed block (2) and the vibration distressing sliding block (3), and the bottom of a vibration distressing top block (4) contacts with the arc surface at the top of the pressure ring and is connected with the vibration distressing fixed block (2) and the vibration distressing sliding block (3) through four screws. The invention solves the radially pressure ring clamping problem in the vibration distressing of the satellite mechanical experiment pressure ring and acquires the advantages of low manufacture cost, convenient and intuitive use, strong suitability and generalization, and the like.

Description

technical field [0001] The invention relates to satellite mechanical test equipment, in particular to a vibration stress relief clamping device for a satellite mechanical test pressure ring. Background technique [0002] In the past, in the vibration test of satellites, the vibration response envelope curve of the bottom surface of the star-arrow adapter was mostly used as the input condition, that is, the star-arrow adapter participated in the vibration test together. In the manufacturing process of satellites and rockets, the star-arrow adapter is a part of the rocket. Therefore, in the vibration test for satellites, in order to better reflect the vibration response characteristics of the individual satellite, the star-arrow adapter should be removed from the vibration characteristics of the whole satellite. It is most reasonable to move the input condition up to the star-arrow separation surface. At present, more and more satellites adopt the vibration test mode without ...
