This paper presents a novel quasi-zero stiffness (QZS) isolator designed by combining a disk spring with a vertical linear spring.
The static characteristics of the disk spring and the QZS isolator are investigated.
The optimal combination of the configurative parameters is derived to achieve a wide displacement range around the equilibrium position in which the stiffness has a low value and changes slightly.
By considering the overloaded or underloaded conditions, the dynamic equations are established for both force and displacement excitations.
The frequency response curves (FRCs) are obtained by using the harmonic balance method (HBM) and confirmed by the numerical simulation.
The stability of the steady-state solution is analyzed by applying Floquet theory.
The force, absolute displacement, and acceleration transmissibility are defined to evaluate the isolation performance.
Effects of the offset displacement, excitation amplitude, and damping ratio on the QZS isolator and the equivalent system (ELS) are studied.
The results demonstrate that the QZS isolator for overloaded or underloaded can exhibit different stiffness characteristics with changing excitation amplitude.
If loaded with an appropriate mass, excited by not too large amplitude, and owned a larger damper, the QZS isolator can possess better isolation performance than its ELS in low frequency range.
