Wind power structure vibration isolation device based on photonic crystal and anti-vibration wind power tower
The invention provides a wind power structure vibration isolation device based on photonic crystals and an anti-vibration wind power tower, the vibration isolation device comprises first vibration isolation units and second vibration isolation units, the multiple sets of first vibration isolation units are sequentially connected from top to bottom to form a multi-layer structure, and the second vibration isolation units are connected to the lower ends of the first vibration isolation units; the first vibration isolation unit comprises a first substrate, a connecting rod and photonic crystal unit cells, the photonic crystal unit cells are periodically distributed on the surface of the first substrate, and the connecting rod is connected to the lower end of the first substrate; the multiple sets of first vibration isolation units are connected through connecting rods. The second vibration isolation unit comprises a second substrate, a support and photonic crystal unit cells, the photonic crystal unit cells are periodically distributed on the surface of the second substrate, and the support is connected to the lower end of the second substrate; the vibration isolation device can be installed in a wind power tower structure, and the vibration isolation unit can attenuate elastic waves propagating in a wind power tower. The adjustability of the vibration isolation frequency can be realized by changing the group number of the vibration isolation units and the periodic distribution of the phononic crystal unit cells.
