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.
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 strain on the skin surface.The experimental results in engineering applications were summarized including flight test,fatigue test and electromagnetic interference test.And on this basis,the development direction of the EIDI technology was prospected.
