Abstract :
A simulation of a new vibration isolation system using negative stiffness is proposed in this paper. The vibration isolation can be improved by incorporating a negative stiffness such that the dynamic stiffness is much less than the static stiffness. This paper is concerned with the nonlinear analysis using Harmonic Balance (HB) method of a High-Static-Low-Dynamic-Stiffness (HSLDS) system. The system consist of an isolated mass arranged in such a way it is attracted by other magnets located at each spring ends. The computer simulation agrees reasonably well for both Duffing oscillator and HB analysis.simulation agrees reasonably well for both Duffing oscillator and HB analysis.
