Abstract

In recent years, the unfolding capability and vibration-isolation properties of spacecraft have received increasing attention. Several studies have achieved deployability through origami structures and low-frequency broadband vibration isolation using origami-inspired meta-structures (OIMs). However, traditional origami prototypes do not fully satisfy aerospace engineering requirements. In this study, a new origami-inspired meta-structure with low-frequency broadband vibration-isolation performance was proposed by combining the geometric characteristics of Kresling origami and waterbomb-based origami. The bandgap distribution and transmission rate of the OIMs were investigated through numerical simulations and a transient displacement study to evaluate the vibration-isolation performance of the OIMs. Modulation of the band structures by changing the geometric parameters was also examined. Experimental tests were conducted to demonstrate and validate the vibration-isolation properties of the proposed meta-structure. The transmission rate and bandgap results were in good agreement. Wider bandgaps are achieved through the gradient design, and the truss design makes OIMs more suitable for engineering applications. This study presents a new origami-inspired meta-structure that provides a strategy for application of origami in aerospace engineering.
