摘　　要：论述了国内外各种超低频隔振系统的研究状况。介绍了由单摆改进而成的倒摆、折叠摆、X 摆和锥摆等超低频水平隔振系统。分析了刚度非线性的实现方法及正负刚度并联技术在超低频垂直隔振系统中的应用。同时介绍了自行研制的正负刚度并联超低频隔振系统。The results on the study of ultra-low frequency isolator are summarized. The inverted pendulum, folded pendulum, X pendulum and conical pendulum ultra-low frequency vibration isolation systems, which are developed from single pendulum, are introduced. The methods of realization of nonlinear stiffness and applications of combined positive and negative stiffness in ultra-low frequency vibration isolation are analyzed. The combined positive and negative stiffness isolators, which are developed by us, are also introduced.
