Development and Validation of a Dynamic Model of Magneto-Active Elastomer Actuation of the Origami Waterbomb Base

Origami, which was once a purely artistic field, has recently become a source of novel engineering ideas and products. Many of the everyday objects we use could benefit from being capable of folding into a more compact state for storage. Several examples of recent origami-inspired designs include a foldable space solar array, disposable medical forceps, and inexpensive, customizable robots. Engineers are particularly interested in self-folding origami, where a sheet of material folds itself into a number of shapes in response to electricity, temperature, or a magnetic field. To assist in the creation such self-folding sheets, it is important to simulate how they might fold and behave using computer software, which can be referred to as a dynamic model. In this work a magnetically-activated, self-folding dynamic model is created of the origami waterbomb base, a fundamental origami model. The accuracy of the developed dynamic model is then verified against an experiment which was performed for this purpose. The model is shown to predict the experimental results reasonably well, demonstrating the potential use of the dynamic model as a design tool for future origami-inspired products.
