Deployable antenna is the key equipment of satellites and other spacecraft, it can realize the information transmission between the spacecraft and earth. In order to enrich the mechanism configurations of space deployable antenna, a double-ring truss deployable antenna mechanism is proposed in this paper, and it is decomposed into a plurality of mechanism units. Based on screw theory, degree of freedom (DOF) of the mechanism is analyzed, the result showed that it has only one DOF. Then, velocities of each component in the double-ring truss deployable mechanism unit are analyzed, their angular velocities and linear velocities were obtained. Finally, a three-dimensional model of this mechanism is established in Solidworks software, based on the three-dimensional model, numerical calculation and simulation verification are carried out, and simulation results verified the correctness of the theoretical analysis. The double-ring truss deployable mechanism proposed in this paper has a good application prospect in the field of aerospace, and the analysis method based on screw theory provides a good reference for other spatial deployable mechanisms.
