板式双边永磁电动悬浮电磁力计算
Calculation of Electromagnetic Force of Plate Type Null Double Side Permanent Magnet Electrodynamic Suspension
摘要
Abstract
In view of the existing weaknesses, a new suspension system, composed of conducting sheet and double Halbach array, was proposed in this paper. Compared with single Halbach array system, this device could create least drag force, and it is more suitable for urban transportation. Analytic and finite element methods were used to calculate the forces created by this device. First, the differential equations of magnetic vector potentials were built, and accordingly the distribution of eddy current can be deduced. Second, in order to get the expression of forces, the relationship between magnetic field and current was studied. 2D and 3D finite element models were built. The magnetic forces, field and eddy current in different velocities were calculated. The relative error between analytic method and 2D FEM is 1.7%. At last, compared with single Halbach suspension system, the levitation-to-drag ratio highly increased in this model.关键词
