| 中文摘要: |
| 航天器微振动、精密仪器低频振动以及船舶汽车宽频振动的隔离是传统线性隔振系统难以实现的。准零刚度隔振系统具有高静刚度、低动刚度的特性，可在不损失静刚度的情况下实现低频隔振，其在微振动、低频振动、宽频振动等领域一直是国内外学者研究的热点。介绍了准零刚度的概念及其负刚度结构，在此基础上，对各结构进行了评述，指出了各结构的优势与不足，总结了准零刚度隔振系统在汽车隔振、机械制造、航空航天等方面的应用，并对准零刚度结构的后续研究提出了展望。 |
| 英文摘要: |
| The isolation of micro-vibrations in spacecraft, low-frequency vibrations in precision instruments, and broadband vibrations in ships and vehicles poses challenges that are difficult for traditional linear vibration isolation systems to address. Quasi-zero-stiffness (QZS) vibration isolation systems, characterized by high static stiffness and low dynamic stiffness, achieve low-frequency vibration isolation without compromising static stiffness. Consequently, they have been a persistent research focus in fields such as micro-vibration, low-frequency vibration, and broadband vibration isolation for scholars globally. This paper introduces the concept of quasi-zero stiffness and its negative stiffness structures. Based on this foundation, various structures are reviewed, highlighting their respective advantages and disadvantages. The applications of QZS vibration isolation systems in areas such as automotive vibration isolation, machinery and manufacturing, and aerospace are summarized. Finally, future research prospects for QZS structures are proposed. |
