Metamaterial vibration isolator

The invention belongs to the technical field of vibration and noise reduction and particularly relates to a vibration isolator. The metamaterial vibration isolator comprises a metamaterial vibration isolation component and other components serving as structural components, namely an upper end cover, a limiting protective hood, a lower base plate, surface rubber coating layers, fastening bolts, a bottom implanted framework, an upper implanted framework, rubber plugs and a sealing gasket. According to the metamaterial vibration isolator, the metamaterial technology is utilized; limitation of certain apparent natural laws of traditional vibration isolation materials is broken through; the metamaterial function exceeding common intrinsic properties of original substrates is achieved, and thus the contradiction generated between low intrinsic frequency and large static deformation of a vibration isolator can be well regulated; the vibration isolation effect in the main bearing direction and anti-swinging performance in the non-bearing-direction of the vibration isolator are achieved at the same time; and a new path is provided for reducing vibration and noise of a ship or warship.
