Effect of the Time‐Varying Damping on the Vibration Isolation of a Quasi‐Zero‐Stiffness Vibration Isolator

open access: yesShock and Vibration, Volume 2020, Issue 1, 2020., 2020
This study focuses on the effect of damping changes on the vibration isolation of a quasi‐zero‐stiffness vibration isolator. A nonlinear‐vibration equation for the quasi‐zero‐stiffness vibration isolator is found and solved using the multiscale method. Then, the vibration characteristics before, in the process of and after the damping change, are also ...
