建立了电脉冲除冰实验系统的二维电磁涡流场分析模型,提出了数值计算后处理求解试验蒙皮表面除冰激励分布的方法,并利用有限元动力分析方法建立了试验蒙皮的三维动力分析模型,通过在模型上加载后处理所得的表面瞬态压力,仿真获得了试验蒙皮的响应加速度,最后引入加速度实验用以验证模拟值。结果表明,基于二维电磁涡流场数值计算后处理求解除冰激励与有限元动力分析试验蒙皮的方法,所得的加速度与实验测量值吻合较好,因此说明了所述方法的正确性,可为电脉冲除冰系统的冰层破坏分析奠定基础。
A two-dimensional electromagnetic eddy current analysis model of the experimental system of the electrical pulse deicing is established. A numerical calculation and post-processing method for solving the deicing driving distribution on the skin surface is proposed. The three-dimensional dynamic force of the experimental skin is established by using the finite element method Analyze the model, and obtain the response acceleration of the test skin through the transient pressure of the surface after loading the model. Finally, the acceleration experiment is introduced to verify the simulation value. The results show that the proposed method is based on two-dimensional electromagnetic eddy current field numerical calculation and postprocessing to solve the deicing excitation and finite element dynamic analysis test skin. The obtained acceleration agrees well with the experimental measurement, so the correctness of the method is demonstrated. Which will lay the foundation for the ice damage analysis of the electrical pulse deicing system.
