| 摘 要： | 对三级弯曲弹簧构成的隔振系统进行了研究，该系统是为引力波探测而设计制造的，它全部由金属构成，结构紧凑，共振频率低．在质心附近悬挂质量并用薄钢片连接弹簧与钢棒，减少了系统正交振动模式之间的耦合．实验结果表明，该系统的三个垂直共振模式分别为１．２８Ｈｚ，２．０９Ｈｚ和３．５６Ｈｚ，水平模式为０．６７Ｈｚ．测量结果表明，该系统具有很好的隔振效果，在１０Ｈｚ处达到近７０ｄＢ的衰减．

| Abstract: | The isolation vibration system of a tree stage curved spring for wave detectors is presented which characterizes all metal structure, compact form and low resonant frequencies. The cross coupling between the orthogonal directions of the system has been reduced through suspending the mass near the center of the mass and connecting a rod and the spring with a thin steel blade. |
