A Study on Magnetic Force of the Large Displacement Hybrid Suspension System Based on Finite Element Method

A method for the computation of local magnetic force in suspension system is proposed. Precise calculation of magnetic force in electromagnet is significant to structure design. Therefore, on the basis of finite element method (FEM) and local virtual work method, a mathematical model is built according to the principle of virtual work equivalent, so as to calculate the magnetic force. Application shows it has good accuracy and extensive applicability.
