| Abstract | In recent years, vibration isolation with quasi-zero stiffness has become an emerging research area. Great amount of efforts have been made by researchers and engineers since its property of high-static-low-dynamic stiffness. It shows significant superiority on isolating vibration and supporting sufficient load simultaneously, especially under low and ultra-low frequency excitation. The current state-of-the-art literature study on quasi-zero stiffness vibration isolator (QSVI) is presented in this paper. The existing devices are classified into four types based on the negative stiffness elements, including spring, pre-buckled beam, magnet and nonlinear structure. The concept, characteristics and realisation of these QSVIs are summarized. In addition, the paper places its special interest in the comparative analysis of the properties of four representative QSVIs, including effective stiffness region, amplitudefrequency response and vibration isolation effect under force excitation. Finally, the evaluation results and general advice are proposed. |
