Abstract
In order to calculate the electro-magnetic force on skin and changes with time more accurately, the working mechanism and process of the electro-impulse de-icing (EIDI) system were studied. The current in circuit of the system was calculated and analyzed. The electromagnetic field of the system was simulated by solving the Maxwell equations. Electromagnetic force time history was calculated and analyzed. The distribution of flux density, eddy current density and transient electromagnetic force density on skin was acquired. Meanwhile, it was accurately acquired how electromagnetic force changed with time by simulating the real circuit working whose inductance was influenced by skin. Moreover, considering that skin effect affects the eddy current and electromagnetic force density, finite element method is more reasonable for calculating the distribution of electromagnetic force on skin.
