摘要

In this paper, a flat type vertical-gap passive maglev vibration isolation unit(FTVPMVIU) with low stiffness is proposed. The magnetic field distribution is calculated semi-analytically by using equivalent current model. The expression of force is derived based on the equivalent current model and Lorentz force law. A method for electromagnetic design of the unit is also discussed. The natural frequency FTVPMVIU can be optimized to near 0, which is suitable for low frequency vibration isolation.
