Design and Analysis of the Scissors Double-Ring Truss Deployable Antenna Mechanism

摘要：

　　With the development of the aerospace industry,large deployable antennas have been widely applied in various spacecrafts,in order to improve the stiffness of the ring truss deployable antenna,this paper proposed a scissors double-ring truss deployable antenna mechanism.The double-ring truss mechanism is divided into a plurality of hexahedral deployable units,and the geometric conditions for the double-ring form of the scissors double-ring truss mechanism is investigated with the consideration of the effects of joint size.Based on the screw theory,the degree of freedom (DOF) of the hexahedral deployable unit is analyzed,the result showed that it only has one DOF,the simulation model of the double-ring truss is built and the deployable feature of the whole truss mechanism is verified through the deploying process.
