摘要: 为了更有效地进行电脉冲除冰系统(EIDI)的电路参数设计,利用能量守恒原理研究了电脉冲除冰中系统振动能量的非线性等效负载,并推导了与系统参数相关的非线性等效电路模型.在ANSOFT Maxwell电磁场有限元环境中建立了轴对称圆柱型脉冲线圈的三维瞬态电磁场仿真模型,采用数值拟合的方法得到在除冰激励周期内法向电磁力的表达式;在此基础上研究了铝板蒙皮在该脉冲力作用下的形变表达式和电磁力做功情况.最终利用非线性等效电路模型设计了不同气隙间距下的储能元件电路参数,且通过实验验证了本文方法的正确性,为电脉冲除冰系统的设计提供了理论依据.

Abstract: In order to design the circuit of the electro-impulse de-icing system more effectively, nonlinear equivalent load of the electro-impulse de-icing (EIDI) system was analyzed by the law of conservation of energy which was on behalf of the vibrational energy, and nonlinear equivalent circuit model related to the system parameter was established. A three-dimensional transient electromagnetic field simulation model for modeling the axisymmetric ring-type pulsed coil was presented, which based on finite element simulation software ANSOFT Maxwell, and the normal electromagnetic force expression during the complete deicing cycle was obtained by numerical fitting method; the aluminum plate deformation expression was computed which induced by the normal electromagnetic force, and the work done by the electromagnetic force was analyzed. The circuit parameter in the different coil-aluminum-plate gap was designed by using nonlinear equivalent circuit model.This parameter is consistent with experiment parameters, which verifies the correctness of the method and provides the theoretical basis for the EIDI system.

Key words: electro-impulse de-icing (EIDI) system, law of conservation of energy, pulsed electromagnetic force, nonlinear equivalent circuit, coil-aluminum-plate gap
