BUTTERFLY-WING DEPLOYABLE MEMBRANE SYSTEMS
A novel deployable membrane structures, namely Butterfly-wing structures, for space enclosure are proposed in this paper. These structures are aimed at rapid erection and easy transportation. The structure is developed based on the idea of integrating the tensioned membrane, which is made of high strength fabric, into the deployable supporting structure, which is made of tubular steel sections. This paper presents the morphological study to illustrate the conceptual design, the generative design to generate different innovative structural forms, the parametric study to provide optimum design parameters and the physical prototype test to verify the design concept and deployability of Butterfly-wing structures. The variety of these structures provides various deployable forms to enclose applications of different shape and size. The optimum design parameters which are determined based on the comparison of weight efficiency can be used as the design guideline for practical applications of Butterflywing structures. The physical prototypes demonstrate that the deployment of the proposed structures is efficient and able to open and tension the membrane. In addition, the membrane can act as the tension components to restrain the deployment and achieve self-stress equilibrium state of the structures.
