Short summary
A double-layer ring truss deployable antenna mechanism is proposed, which is connected by a scissor-like structure. The degrees of freedom, six-dimensional velocity, and acceleration are calculated using spiral theory, and the dynamic model is established. Simulation software is used to verify the simulation, and the prototype is made at a reduced scale. Because the satellite antenna is very important, we decided to study the supporting frame.
