Dynamic Properties of a Novel Vibration Isolator with Negative Stiffness

Objective The vibration isolator with quasi-zero stiffness can achieve extraordinary isolation performance in high bands for its negligible elastic force. The novel dual-chamber solid and liquid mixture (SALiM) isolator, designed for vibration reduction of heavy machines, can obtain a quasi-zero-stiffness property in certain frequency band. This article implemented a deep analysis on the mechanism of the novel isolator.
