Description
Jeseung Lee, Sophie Leanza, and Ruike Renee Zhao introduced springs made from rod origami in a 2026 engineering study. Springs anchor vibration control everywhere, but a normal spring's stiffness is fixed at manufacture, while machines face changing vibration environments.
Their RodOri springs are built from pre-stressed, naturally curved elastic rods. Tuning each rod's natural curvature and cross-section programs when it snaps through buckling and how stiff it feels afterward. Assembling springs of equal length but different snapping points creates a multistable metamaterial that reconfigures step by step as load rises. Each stable state carries its own resonance behavior, giving broad and fine control of dynamic response. Simulations and experiments support the design principle for adaptive mounts and isolators.
