Reduced-order modelling of the deployment of a modified flasher origami for aerospace applications

In this paper, we simulate the nonlinear deployment mechanics of a modified flasher origami structure designed to be a deployable solar panel. We compare reduced-order bar-andhinge simulations, where panels are modelled as bar assemblies connected by joints and torsional springs, with results obtained from commercial finite element software. Through this comparison, we demonstrate the ability of the bar-and-hinge approach to capture key features of the origami behaviour at a fraction of the time needed to perform regular finite-element simulations. We also provide details on how to properly tune the bar properties to simulate panels made bonding printed circuit boards to textile, and the joint properties to mimic folds that are made of fabric and flexible circuit interconnects.
