Abstract

Annular metamaterials (AMs) which can suppress radial vibrations have received significant attention. In this paper, a novel AM is designed to suppress radial vibrations. Utilizing a mass-spring model, the radial vibration bandgaps (BGs) of the AM are calculated theoretically. Finite element simulations are conducted to analyze the mechanism behind the formation of these BGs, with results indicating pronounced local resonance characteristics within the BGs range. Further investigation into the vibration transmission characteristics of the AM is conducted using both finite element analysis and experimental methods. Further studies on the vibration transmission characteristics of the AM are performed using finite element analysis and experimental methods. The findings confirm a strong alignment between the theoretically calculated BGs and the observed vibration transmission characteristics, demonstrating the efficacy of the AM in suppressing radial vibrations within the BGs. The AM proposed in this study offers wide engineering applications in annular component, such as vibration reduction in rotating machinery and pipeline.
