Analytical stiffness calculations of a cone-shaped magnetic vibration isolator for a micro balance

The accuracy of a micro balance is highly dependent on the level of floor vibrations. One strategy to reduce floor vibrations is a magnetic vibration isolator. Magnetic vibration isolators have the possibility to obtain a zero-stiffness region, which is beneficial for attenuating vibrations. In this paper a 3D analytical magnetic surface charge model is used to calculate the stiffness of a cone-shaped magnetic vibration isolator for different angles.
