摘要
总结了电脉冲除冰(EIDI)系统电动力学模型的研究现状,针对几种常见的计算模型进行了分析,以Bernhart-Schrag模型为例,重点阐述了电动力学模型的理论基础、等效模型的建立以及状态方程的求解,分析了模型的正确性.针对由环状平绕线圈及金属平板构成的EIDI简化系统,Bernhart-Schrag模型可以预测通电线圈中电流的变化规律以及蒙皮受到的脉冲作用.
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.
