Vibration control in rotor chain structures with dual topological states
Abstract
Rotor chain models (RCMs) offer a mathematical framework for studying wave propagation in periodic structures, such as folding-inspired metamaterials. These systems support topo- logically protected states (TPS) that localize vibrational energy, independent of material defects. This study presents a 1D RCM with spring-hinge elements, allowing control over vibration localization by adjusting stiffness and angles. The model predicts dual topologi- cal states at zero and finite frequencies, enhancing wave control and vibration mitigation. These findings contribute to resilient mechanical designs, including origami-inspired struc- tures, with applications in aerospace, deployable systems, and noise reduction technologies.
