Research on Anti-Vibration based on Screw Fixation and Friction-Assisted Fixation Method for the Space Payloads

Abstract

Rack is kind of the experimental platform that used in the space station for performing scientific experiment. Many payloads are mounted on Rack with limited operating space. The shipment of a Rack to its final destination in orbit is far more complicated than for all other commercial products. The launch vehicle-induced vibration and shock environment can be a payload killer. Based on the limited operating space, this paper proposes a screw fixation and friction-assisted fixation method. Through establishing the force and the parameters of the screw fixation and friction-assisted fixation based on the payload, deriving the mathematical model and carrying out the dynamic environment test. Test results match theoretical results quite well. The screw fixation and friction-assisted fixation method can effectively resist excessive dynamic and shock loads.
