Abstract :
A new kind of vibration isolator, which is base on negative-stiffness theory, is made out for nano manufacture. In this paper, vibration isolation theory is mentioned to further explain negative-stiffness, and then Euler Columns and another negative-stiffness structure are introduced. Furthermore, the stiffness expression is figured out. Finally, a negative-stiffness vibration isolator is made to prove the theory and experiments also shows that its nature frequency is 0.45 Hz and can isolate 79% of vibration at 1.9 Hz and 97% at 4.9 Hz.
