Abstract

Abstract: The Electro-Impulse De-Icing（EIDI） system, which possesses simple structure, light weight and high efficiency etc. Excellent performances, has been a main development direction of airplane de-icing system in future. For airplane EIDI design, it is an essential reference to simulate electro-impulse de-icing process and study de-icing criterion. In this paper, based on studying and comparing the relational technology literatures, an improved de-icing criterion is proposed. In the criterion, the normal stress and interfacial shear stress are considered during the de-icing process. Numerical experiments show that the criterion is reasonable, accurate and applicable for simulating electro-impulse de-icing process.

Key words: electro-impulse de-icing, de-icing criterion, simulation

摘要： 电脉冲除冰系统以其结构简单、重量轻、效率高等优良性能，已成为未来飞机除冰系统的主要发展方向之一。开展电脉冲除冰过程的动力学仿真分析与冰层松脱准则研究，能够为飞机电脉冲除冰系统设计提供基本参考依据。在研究比较相关技术文献的基础上，综合考虑了冰层松脱过程中法向正应力与层间剪应力的共同作用，提出了一种改进的冰层松脱准则；数值算例证实该准则合理、准确，能够应用于电脉冲除冰过程的仿真分析中。
