A new high-static-low-dynamic stiffness vibration isolator based on magnetic negative stiffness mechanism employing variable reluctance stress

To improve the passive control effect on low frequency micro-vibration of structures with high static support stiffness, this paper proposed a high-static-low-dynamics stiffness vibration isolator (HSLDs-VI). This device is equipped with a magnetic negative stiffness mechanism that can provide high magnetic negative stiffness to counteract high static stiffness. The magnetic mechanism is composed of a magnetic spring with negative stiffness...
