Abstract
As an electromechanical de-icing system, electro-impulse de-icing (EIDI) technology has broad application prospect. In the present paper, structural dynamics characteristics of a simplified EIDI system consisting of coil and metal plate were numerically and experimentally studied. A finite element simulation model of an EIDI system was constructed, and the structural dynamics was analyzed by FEM software MSC/NASTRAN. The inherent characteristics (modal and frequency) as well as the transient response of the model were analyzed. The simulation was then validated by the experimental measurement. The structure dynamics characteristics of an EIDI model were studied. The maximum strain and displacement of the skin surface characteristic locations were evaluated with different capacitance, voltage and clearance between the skin and the coils. It is found that under the electro-impulse, the maximum displacement of the metal plate presents a saddle-like distribution. Increasing the capacitance and voltage will increase the impulse peak value and the structural deformation, and meanwhile, the strain of fixed location will be decreased.
