Multi-level magnetic system for isolation of vibration
Abstract:
A multi-level magnetic system includes first and second magnetic structures and transitions between an attract mode and a repel mode when the first and second magnetic structures are separated by an equilibrium separation distance. The multi-level magnetic system is placed between two objects and configured to oscillate about the equilibrium separation distance in response to a vibration from a motion source. The oscillation about the equilibrium separation distance causes the multi-level magnetic system to function as a low pass filter that substantially attenuates vibrations above a cutoff frequency thereby limiting the conducting of the vibration between the two objects.
