RESEARCH ON WRAPPING-BASED FOLDING FOR DEPLOYABLE MEMBRANE STRUCTURES: FROM PATTERN DESIGN TO KINEMATIC ANALYSIS

To meet the stringent engineering demands of high stowage ratios and of reliabilities for space membrane structures, this research presents an origami-based wrapping-folding scheme. Based on two bio-inspired units, termed "leaf-out" and "leaf-in", a library of novel topological configurations for wrapping-folding is constructed by systematically combining their connection modes, crease patterns, and geometric parameters. Furthermore, for a representative configuration, its ideal kinematic path is analytically derived using the mechanism theory and is subsequently used to drive an explicit dynamic simulation. The research results demonstrate that the proposed scheme achieves an orderly and stable quasi-static folding process. Strain energy is highly concentrated at the predefined creases, ensuring that the main membrane surfaces remain in a low-stress state, thereby validating its engineering feasibility. This work establishes an integrated evaluation methodology that combines topological design, kinematic analysis, and dynamic validation, providing a theoretical foundation and a viable technical approach for designing high-performance wrapping-folding membrane structures.
