Description
Summary:The Origami “flasher” model holds immense engineering promise due to its ability to alternate between a compressed 3-dimensional form and a deployed 2-dimensional form. While zero-thickness mathematical models have been thoroughly covered, dynamic modeling and material exploration are essential for the successful design of finite-thickness models. In this research, the mathematical effects of parameters such as center polygon size, unit panel length, and crease arrangement on flasher surface area optimization are first established. Software is then used to create a dynamic model that combines kinematic analysis with material properties to visualize the folding geometry and internal strain of the flasher pattern and to identify points of analysis for the experimental model. Finally, a stored-energy-based deployable experimental model is made using Yupo paper and video analysis done to understand damping behavior, deployment trajectory, and torque distribution. A discussion on design considerations for flasher patterns follows and potential topics for future research are set forth.
