薄い円形膜の折りたたみ法のモデル化 (等角ら旋様式による折りたたみ法) Modelling of Compact Folding/Wrapping of Flat Circular Membranes (Folding Patterns by Equiangular Spirals)
This paper describes the folding/wrapping methods of thin flat circular membranes by using folding patterns prescribed by combining two groups of equiangular spirals. By using both folding conditions at nodes and continuous conditions of equiangular spiral type folding lines in the membranes, 2 kinds of folding patterns have been analytically designed ; (1)folding patterns consisting of pseudo equiangular spiral (zigzag type spiral) and equiangular spirals, and (2) folding patterns consisting of two groups of equiangular spirals. The availability of present folding/warpping methods of thin circular membranes has been verified by manufacturing paper and very thin metal sheet samples.
