Deicing Excitation Simulation and Structural Dynamic Analysis of the Electro-Impulse Deicing System
A two-dimensional electromagnetic eddy current field analysis model of the experimental electro-impulse deicing system (EIDI) is developed. Additionally, a numerical post-processing method is proposed to calculate the deicing excitation exerting on the testing skin. Moreover, a three-dimensional dynamic analysis finite element model of the testing skin loaded the excitation is built for evaluating the response accelerations. Then, the calculated accelerations are compared with the experimental measured data to validate the correctness of the proposed methods. It is obtained that the results agree well, which indicates that it is feasible to use the method of post-processing pressure distribution for solving the deicing excitation and the method of structural dynamic finite element analyzing the testing skin for simulating dynamic response. The presented methods pave a way for ice failure analysis of the EIDI system.
