Characteristics of triangle in triangulated cylindrical origami with axial load test for space deployable structures

Triangulated cylindrical origami (TCO) has multiple parameters that can control and predict the transformation process. In the present study, the Kresling pattern was constructed by congruent triangles in helical formation. It is shown that triangle angles have a huge impact on load-bearing ability. Experimental tests and mathematical calculation of Kresling-patterned triangulated cylinder in different α angles with one constant angle for all specimens were developed. This study aims to understand the relevancy and distinction of experimental and mathematical approaches with axial load in the process of creating single unit Kresling pattern origami. The specimens were tested with the axial test without applying twist movement on it. The structures could hold up to 176 N for the most significant angle observed. The reversible deformation of TCO from deployed to folded state with axial load was performable with α angle below 50° with 136 N of load. Based on the experiment, the larger the α angle, the more dependent on the twist. The axial load test without twist movement shows similar energy distribution during deformation process. Further observations related to overall strength of TCO due to difference in the value of mathematical and experimental results are required. The present research could give a contribution related to the design method for the fabrication of Kresling pattern origami.
