摘要：

Euler spring vibration isolators can be significantly improved by implementing anti-spring techniques. Here we report geometric spring coefficient reduction techniques which allow an order of magnitude improvement in the effective spring coefficient, achieving a resonant frequency of 0.3 Hz. In this Letter we analyse the various effects which determine the behaviour and stability of low frequency Euler stages. (C) 2005 Elsevier B.V. All rights reserved.
