“…The global mesh size of Miura-SGRMO was set to 0.055 mm. The Miura configurations required the pre-incorporation of creases, the geometric shape and material properties were altered at the crease [45][46][47], and both the elasticity and plasticity of the crease needed to be considered. We utilized the rotational elastoplastic connectors to simulate the crease.…”

Origami-based membrane structures have shown great potential to revolutionize the construction of deployable and lightweight space structures in the future. However, the efficient unfolding mechanism puts forward major challenges to the practical realization of space-deployable structures. Here, a smart grid-reinforced membrane origami (SGRMO) is presented. The unfolding action hinges upon the application of forces facilitated by shape memory polymer composites (SMPCs). Subsequent locking action ensues through the restoration of the initial rigidity, accomplished via cooling mechanisms. This novel structure achieves the required lightweight and functionality by employing the grid design concept and effectively reduces the decline in unfolding extent caused by irreversible plastic deformation at the crease. Its recovery properties, including unfolding angle, distance, and surface precision, are experimentally and analytically investigated under different conditions. The results indicate that the structure can be reliably unfolded into the predefined shapes. In the case of Miura-SGRMO, the optimal surface precision is attained when the angle-ψ registers at 30°. The results of this study are expected to serve as the design of ultra-large flexible solar arrays and deployable antenna structures.

“…Furuya et al [9] treated the uniformly loaded Z-folding membrane structure as a one-dimensional structure and analyzed it based on the curved elastic beam theory. Xia et al [30,31], Satou et al [22], and Dharmadasa and Jiménez [3] also proposed several beam-theory-based models for the Z-folding structure. Schenk et al [23,14,10,33] used the so called barhinge method that analyzes the origami structure as an equivalent pin-jointed truss frame.…”

In this paper, the origami membrane is modeled as a flexible multibody system and its deployment is simulated based on the absolute nodal coordinate formulation. The nonlinear anti-deployment effect of crease is integrated into the multibody system via the virtual work principle. The facet is modeled by the thin shell element and the crease is constructed as a nonlinear torsional spring with specific position and gradient constraints. The behavior of the crease is parameterized based on the experimental data. The modeling approach is verified by the numerical/experimental reference of the Z-folding structure in the existing literature. For the multi-crease origami membrane model considering the crease effect, a form-finding method to obtain the initial configuration of the flexible origami is proposed based on the principle of minimum potential energy. The deployment of the classical Miura-ori unit membrane structure is analyzed. The magnitude of driving force is estimated based on the force analysis of rigid deployment. Based on the simulation result of flexible deployment, the driving force is planned to achieve a stable deployment with a constant increase speed
