Active Control of Quasi-Zero-Stiffness Vibration Isolator with Variable Load

International Journal of Structural Stability and Dynamics
Quasi-zero-stiffness (QZS) isolator has great application potential in the field of low-frequency vibration isolation due to its high-static and low-dynamic (HSLD) nonlinear stiffness characteristic, but it is precisely this characteristic that makes it very sensitive to load changes.
