摘要：This paper explores a novel approach to the calculation of the dynamic magnetic field under the feedback control and analyzes the frictional characteristics of a magnetic suspended flying vehicle by ANSYS. The numerical calculation result is compared with the experimental data to verify the accuracy and the effectiveness of the approach which suggests a method of the calculation of the dynamic magnetic field under the feedback control by ANSYS. Research results indicate that the equivalent friction coefficient of the magnetic suspended flying vehicle is not a constant which is not only related to the running speed and the weight of the vehicle but also to the resistivity of material of the guide rail and some control parameters of the vehicle. In other words, the smaller the air gap of the vehicle, the smaller the equivalent friction force. The equivalent friction force increases as the running speed increases. With the same air gap and running speed, the equivalent friction force increases with the increase of the weight of the vehicle.
