In this paper, we consider a one-dimensional model of magnetic suspension in the case of a variable magnetic field. Analytical expressions for the averaged over a period of an external current source for the suspension equilibrium position are obtained. It is shown that the magnetic stiffness of the suspension has a sign-variable character in the general case. An expression for the averaged value of the magnetic stiffness is obtained and it is shown that this value is always positive.

摘要

In this paper, we consider a one-dimensional model of magnetic suspension in the case of a variable magnetic field. Analytical expressions for the averaged over a period of an external current source for the suspension equilibrium position are obtained. It is shown that the magnetic stiffness of the suspension has a sign-variable character in the general case. An expression for the averaged value of the magnetic stiffness is obtained and it is shown that this value is always positive.
