Parametric Design and Structural Analysis of Deployable Origami Tessellation

摘要

This paper presents a research study on a geometry and mechanism of origami for generating a deployable tessellation structure that will be tested as a large span structural system. The research explores a combination of methods for understanding the structural limitations of deployable origamic geometry by using geometric scripting with a parametric system and finite element analysis tools. This combination of methods allows deployable origamic geometry structures to be evaluated at various scales which provides information on how to optimize the geometry for a given scenario. Analog models based on biological inspirations were initially produced for studying the origamic deployment mechanism followed by a process that translated the model into a scripting based form generation using a parametric system to propagate different permutations of the same origami family. The workflow requires interoperability between the parametric system (Grasshopper/Rhino), Excel, and finite element analysis tool (LS-DYNA). The research investigates the possibilities of extracting geometric and mechanical principles of microstructure for its application to a larger scale structure as an architectural element. A recent paper by the authors discussed the general process from biological inspiration to structural evaluation of the selected origami structure (see Baerlecken et al. [1]). This paper continues the discussion with more additional information related to geometric principles of the selected origami for the case study and the technical details on the interoperability between the parametric and the structural system.
