Design of a deployable ring mechanism using V-fold bars and scissor mechanisms

This paper presents a novel planar single-mobility deployable mechanism using V-fold bars and scissor-shape mechanisms. The basic deployable units of the proposed mechanism is first described, then the kinematic model of the mechanism is set up, based on which we can analysis the kinematic performance of the mechanism. After that, the singularity configuration of the basic deployable unit is analyzed and mobile assembly of the proposed deployable units into large deployable mechanism is also studied. This work provides technical basis for future deployable satellite antenna applications.
