Metamaterial rod piece structure system capable of being used for low-frequency and ultra-low-frequency vibration/earthquake isolation and vibration/earthquake isolation method
The invention provides a metamaterial rod piece structure system capable of being used for low-frequency and ultralow-frequency vibration/shock isolation and a vibration/shock isolation method, the metamaterial rod piece structure system comprises one or more one-dimensional periodic structures, and each one-dimensional periodic structure is formed by combining a plurality of periodic units according to a one-dimensional period; each periodic unit comprises a structure main body, a circular cavity cushion layer embedded into the structure main body, a resonator and a spring, and the resonator is connected into the circular cavity cushion layer through the spring. According to the invention, the resonators are designed in the circular cavity cushion layer, resonance of the resonators with different inherent frequencies is utilized to consume energy propagated through the structure in a low-frequency range, and longitudinal wave propagation inhibition in the low-frequency, ultralow-frequency and high-frequency inner structures can be realized through combination parameter design of the resonators and the circular cavity cushion layer. The invention discloses a form of the structure and a multi-target frequency band vibration isolation method. The multi-target frequency band vibration isolation device is simple in structure, easy to install, good in isolation effect and wide in application prospect.
