Bio-inspired isolators are a novel type of nonlinear isolators by mimicking the bionic
structures and behaviors. Most of them are based on limb-like structures composed of rigid …

Abstract The quasi-Zero Stiffness (QZS) isolation system is a typical nonlinear isolation
system, which has high static stiffness characteristics to improve the bearing capacity and …

An elliptical ring is used to implement a novel type of high-static-low-dynamic vibration
isolation. Under the compression deformation, the elliptical ring produces a nonlinear …
