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...

First, structure analysis of general ring truss deployable antenna and construction of the scissors double-ring truss deployable mechanism are conducted, and the whole mechanism is decomposed to a plurality of mechanism units. Then, degree of freedom (DOF) of the scissors double-ring truss ...
