Summary
This research conducts a thorough examination of an innovative mechanical system inspired by recent advancements in metastructures, specifically focusing on Origami-type structures due to their intriguing unique non-linear stiffness. These structures, when appropriately designed, demonstrate Quasi-Zero Stiffness (QZS) characteristics within a specific working range, aligning with the High Static Low Dynamic (HSLD) stiffness concept. This study investigates the vibration isolation characteristics of Origami-type suspensions, emphasizing their potential as low-frequency passive vibration isolators. The Kresling Origami Module (KOM) is chosen for its compactness and compatibility with 3D printers. The investigation includes a detailed study using Finite Element Analysis and an experimental campaign. It explores the influence of geometric parameters on the non-linear Force-Displacement curve. Moreover, multibody dynamic simulations will be presented and confirm low-frequency isolation properties within the QZS region. The research highlights the transformative potential of Origami-type metamaterials in advancing low-frequency vibration isolation technology. Challenges related to material properties and loading mass variations are discussed, providing valuable insights for future developments in this promising field.
