- •
A novel X-shape structured lever-type isolation system with band-stop property is proposed.
- •
Geometrical nonlinearity of an X-shape structure is helpful to achieve much wider stop-bandwidth.
- •
The width and magnitude of the stop band can all be designed with flexible structure parameters.
- •
The nonlinear stiffness and damping characteristics are very critical for designing the band-stop property.
