Research of electrodynamics in electro-impulse de-icing (EIDI) system

The current status of the research on electrodynamics in electro-impulse de-icing (EIDI) system was summarized in this paper; several common calculation models were analyzed. By taking Bernhart-Schrag model, for example, the theoretical basis of electrodynamics model, the establishment of equivalent model and the solution of state equation were expatiated; the correctness of the model was also analyzed. For the simplified system of EIDI composed of circular flat coil and metal flat plate, Bernhart-Schrag model can help to predict the regular variation pattern of current in the coil and the pulse effect under the skin.
