| 摘 要： | 将电脉冲除冰（EIDI）系统的一个工作周期分解为四个过程,进而分析其工作原理.以冲击摆锤试验和Bernhart-Schrag模型为例,介绍了电动力学方面的研究方法和研究成果.通过蒙皮表面加速度、应变、振动位移等参数,分析了由脉冲力所产生的结构动力学特性.利用蒙皮表面的应变程度,给出了一种除冰预测准则.总结了包括飞行试验、疲劳试验以及电磁干扰试验在内的工程应用试验研究结果.在此基础上,对EIDI技术的发展方向进行了展望.

| Abstract: | The electro-impulse de-icing(EIDI) system was decomposed into four processes,and then its work theory was analyzed.The research methods and results in the field of electrodynamics were introduced,by taking the impacting pendulum test and Bernhart-Schrag model as an example.The feature of structural dynamics generated by pulse power was analyzed through the parameters of acceleration,strain and vibration displacement on the skin surface.A criterion of de-icing forecast was proposed,by making use of the strai... |
