In recent research investigations, Origami has shown great potential for creating reconfigurable structures for achieving various engineering functions. Especially, origami can be designed to fold compactly into very small volumes and then deploy to become large structures, which has led to many deployable system applications. Despite their promising potentials, most origami studies have focused on their static or kinematic features, while the complex and yet important dynamic behaviors of the origami deployment process have remained largely unexplored and unknown. To discover the missing knowledge, this thesis research investigates the dynamics of origami structure deployments, with a focus on Miura origami sheets, fluidic origami tubes, and fluidic multi-tube origami structures as testbeds. We construct a dynamic model for origami structures that captures the combined panel inertial and flexibility effects …
