负刚度的工作原理及应用初探

Research on Theory of Negative Stiffness and Its Application

本文讨论含负刚度弹簧系统的隔振原理,并对这样的系统进行了能量分析.作为该方法的应用,最后给出了等频隔振系统的设计实例.结果表明,含负刚度弹簧的振动系统具有固有频率低、承载能力大、隔振效果好等优点.

This paper deals with the vibration isolation principle of a system with a negative stiffness spring and the energy analysis for this system.As an application of the method, an example of vibration systems with equal frequencies is given. It shows that the system has advantages of low natural frequency,large load supporting ability and good effect for vibration isolation.
