摘要：

In this paper, an approach for conceptual development for vibroacoustic metamaterial structures for realization in aerospace applications is presented. Vibration reduction in the frequency range up to 500 Hz has been evaluated for a composite launcher interstage, designed as a vibroacousitc metamaterial structure based on the local resonance effect. The study involves the analysis of relevant requirements for integration, available space and additional mass. Two approaches for the structural design have been considered. The first approach implies a modification of the host structure to achieve local resonances. The second approach considers adding resonators to compose a vibroacoustic metamaterial structure. Vibration attenuation potential of the interstage as vibroacoustic metamaterial structure is evaluated and designed using finite element method (FEM).
