Abstract
Large deployable mechanisms (LDMs), which consist of a set of basic deployable units, are widely used in aerospace industries, such as deployable masts, antennas, solar panels, etc. The Myard linkage with one degree of freedom can deploy to a planar configuration and fold to a compact bundle, can be used as the basic unit to build the LDM. In this paper, two mobile assembly methods of multi-units are proposed, and the mobility analysis of the novel deployable mechanism is developed. Parametric optimization for the deployable mechanism in an integrated design environment of iSIGHT is developed. The proposed deployable mechanism is optimized toward the goal of maximizing the fundamental frequency and minimizing the structural weight to enhance its stiffness. The prototype is constructed with limited deployable units and the deployable and foldable characteristics are initially verified.
