Abstract
In recent decades, the deployable platform structure for more payloads is usable and attracts the view of researchers and engineers to improve and expand the functions of microsatellites. Generally, torsion springs on hinges are the common driving style on the deployable structure since there is little power supplied on the microsatellite and self-unfolded spring potential energy can be the feasible way. It is uneasy to accurately make the dynamic simulation due to these hinges on the deployed platform structure. In this paper, a kind of triangle-grid deployable platform structure was designed and fabricated. An assumption was made to simplify the nonlinear of the contact elements and gaps on the hinges. A kind of tension rope equivalent was employed to simulate the contact between the end of the bar and the pack plate of the node. The relative dynamic tests were processed and analyzed with the numerical results. In the conclusions, it was verified that this method was practicable and convenient.
