“…In step 2, the rigid bodies along AA' (2, 5, 8, and 11) were fixed with no translation or rotation. And the upper rigid bodies (1,4,7,10) and the lower ones (3,6,9,12) rotated about the Z-axis towards the center by  90 . This was also achieved by a similar setup as step 1.…”

In this paper, cross folding of an elastic sheet, a common folding method in packaging a deployable antenna reflective membrane, was studied numerically with the aim of eliminating material failure in the sheet. The deformation, stress distribution, and peak stress of the sheet, as well as the effects of geometrical parameters on those properties were systematically investigated. Then two methods, i.e., central hole method and central slit method, were explored to reduce the peak stress caused by cross folding. A central slit parallel to the first folding crease was found to be most effective in reducing the peak stress.

“…Deployable antenna reflectors are a typical kind of deployable structures in aerospace engineering, widely used for telecommunication, earth observation and other missions [1][2][3][4][5][6]. An antenna reflector is usually composed of a reflective membrane and a foldable ring that supports the membrane.…”

“…There exist solutions with several modules that allow to form linear truss (Chu et al 2014) in order to deploy Large Deployable Reflector (LDR). Many systems have also been developed like inflatable beams or tape booms for solar sails (Jianzheng et al 2014), conical V-fold bar ring with flexible pre-stressed center for space antenna (Fraux et al 2014) and using flexible connections in order to deploy optical reflectors (Wang et al 2016).…”

Self-Deployable Geometries for Space Applications

Variable-geometry structures are useful in aerospace applications since they are adaptable, from a compact configuration (launch phase) to a spread geometry (operational phase). They may also benefit from the use of flexible joints, which store elastic energy for automatic deployment. Following the development of a self-deploying antenna frame structure with scissors, we propose in this article the geometrical configuration of a new kind of structure, simpler and lighter, minimizing mechanical joints between elements. This topology can form a circular plane or a three-dimensional structure when partially opened. The applications concern auto-tensioning structures such as meshed space antenna, deorbiting sails and also solar panels support structures.
