Metamaterial vibration isolation pile array application system based on inerter damper gain
The invention relates to a metamaterial vibration isolation pile array application system based on inerter damper gain. Metamaterial vibration isolation piles at certain intervals form an array; the metamaterial vibration isolation pile based on the gain of the inerter damper comprises a hollow pile (1), the inerter damper (2) and a resonance subsystem (3), the inerter damper (2) is connected with the resonance subsystem (3) and arranged in a shell of the pile body (1), and the rest space in the pile body is filled with concrete. The resonance subsystem (3) captures stratum vibration waves in a frequency band gap range; and the inerter damper (2) performs mass gain and energy consumption synergy on the resonance subsystem (3) by utilizing inertia amplification of inerter. The inerter mass gain effect is applied to stratum vibration control through the metamaterial vibration isolation pile array, low-frequency stratum vibration can be controlled, meanwhile, the size and quality of the vibration isolation piles are controlled within the range easy to construct, and the metamaterial vibration isolation pile array has good engineering application prospects.
