Magnetic spring device with negative stiffness

摘要

Magnetic spring with negative stiffness comprises at least a first pole body combination of at least three pole bodies (2a, 3, 2b), each of which has opposing magnetic poles, whereby the pole bodies of the combination are aligned so that different polarity poles are opposite to each other and the first and third pole body take up a defined separation distance relative to each other. The second pole body lies between the first and third and the pole bodies can be moved relative to each other. The invention also relates to a corresponding vibration isolation device with at least one inventive magnetic spring device, with more than one spring device coupled in a parallel or serial manner to obtain the required vibration isolation characteristics.
