Novel One-DOF Deployable Network for Plate Structures: Design, Analysis, and Application

The use of deployable structures in various industries and production processes is widespread due to their ability to easily switch between a deployed working state and a folded storage state. This convenience makes them highly beneficial in terms of transportation, storage, and deployment. \n\nIn this paper, we present a new method for achieving the plate forms of deployable structures that can be used for covering purposes. We propose a novel one-degree-of-freedom (DOF) deployable network using Bennett linkages and Bennett-based 6R linkages. By modifying the shape of the links in the network, we are able to obtain a plate form made up of equilateral triangular panels.\n\nWe then conduct a kinematic analysis, studying the motion properties and bifurcation conditions of the proposed deployable network to demonstrate its folding properties. Furthermore, we provide a modified scheme to ensure that the structure forms a closed surface when deployed. To validate our findings, we create physical prototypes and verify the results.\n\nOverall, our proposed method offers a new approach to constructing plate deployable structures, making them more practical and applicable in various industries and production processes.
