结冰是飞机飞行中的重大安全隐患。电排斥除冰器利用电磁排斥力除去冻结在飞机表面的积冰,具有低功耗、高效率、对飞机气动性能影响小、安装简易等优点。本文采用ANSYS仿真软件,利用磁矢量位有限元仿真方法,构建了飞机电排斥除冰器单组排斥元件有限元模型,通过对模型进行电磁—结构瞬态耦合,分析了单组元件尺寸及通入电流峰值对元件运动层所受电磁排斥力强度的影响,得到了单组元件不同尺寸和电流峰值的电磁力强度曲线,进而提出了电排斥除冰系统的设计思路。本文模拟结果与实验吻合度高,较该种除冰器设计时常用的经验公式的计算结果更精确,为电排斥除冰器件的设计提供了精确的理论指导。
Freezing is a major safety hazard in the flight of an aircraft. Electro-repelling deicers use electromagnetic repulsion to remove ice accretion on the surface of the aircraft, which has the advantages of low power consumption, high efficiency, little impact on the aerodynamic performance of the aircraft and easy installation. In this paper, ANSYS simulation software, finite element method using magnetic vector finite element method to build a plane exclusion deicer single set of exclusion element finite element model, the model by transient electromagnetic-structure coupling, the analysis of the single element size and pass The influence of the peak current into the layer on the electromagnetic repulsive force of the element moving layer is obtained, and the electromagnetic force intensity curves of different size and current peak of the single element are obtained. Then the design idea of the electric repulsion deicing system is proposed. The simulation results in this paper are in good agreement with the experimental results, which are more accurate than the empirical formula commonly used in the de-icer deicer design. It provides accurate theoretical guidance for the design of the electrical deicer deicing device.
