Abstract
Origami structures are recognized for their exceptional deformability and programmability, serving as a promising platform for designing mechanical metamaterials. In this paper, a local-resonant polygonal honeycomb origami metamaterial (LR-OHS) is proposed to achieve low-frequency wave attenuation and impact mitigation. The bandgap (BG), transmission spectrum, and mode analysis are investigated in detail through numerical calculations and experimental validation. It is demonstrated that two complete BGs in the low-frequency range are found, and the underlying generation mechanism of these BGs is elucidated theoretically by establishing a mass-spring model. Subsequent research discusses the influence of three significant parameters on the two complete BGs within the region of interest, as well as the broadening of the low-frequency BGs through the merger of two narrow BGs induced by an increasing resonator radius. Furthermore, the impact resistance performance of LR-OHS is evaluated under impact pulses, demonstrating a 43.43% reduction in the peak reaction force compared to its non-resonator origami honeycomb metamaterial. Additionally, parametric analysis of the number of resonators identified an optimal configuration of eight resonators per unit cell, ensuring high performance while satisfying lightweight engineering requirements. This work establishes a design framework for origami-based metamaterials, offering a viable path toward high-performance structures for wave attenuation and impact mitigation.
