Geometric Modulation and Design of Low-Frequency Vibration Bandgaps in Kresling Origami-Based Resonant Systems

This study designs a resonant system based on the Kresling origami structure, utilizing the unique geometric properties of the structure to achieve bandwidth tuning, thereby effectively suppressing vibration propagation within specific frequency ranges. Through theoretical analysis, finite element simulation, and experimental verification, the study systematically investigates how factors such as crease angle, number of layers, and structural symmetry influence the vibration bandgap characteristics. The results show that the Kresling origami structure can form a significant vibration bandgap in the low-frequency range of 60 Hz to 150 Hz, suppressing vibration propagation in the target frequency range. By adjusting the crease angle and number of layers, various bandgap configurations can be achieved. The design of this structure not only enables vibration control on spiral bases but can also be extended to other origami forms, offering broader application potential. Experimental results validate the reliability of the theoretical and simulation analyses, demonstrating the advantage of this approach in simplifying the design and manufacturing of vibration control systems in practical engineering. The study suggests that the Kresling origami-based vibration control system has significant application prospects in fields such as aerospace, automotive, and civil engineering.
