An enhanced dual-resonator metamaterial beam for low-frequency vibration suppression

Structural vibrations seriously affect the working performance of and even cause fatal hazards in host structures. The use of a metamaterial is a novel way to suppress structural vibrations across a wide frequency band. This paper presents an enhanced dual-resonator metamaterial beam (DRMB), where the free end of a traditional series dual-resonator is periodically connected to the rigid body with a spring. The mass and frequency response of the...
