Abstract

Electro-mechanical de-icing systems are low-energy ice protection solutions based on ice fracture mechanisms. This article focuses on resonant electro-mechanical de-icing systems that actuate modes of flexion, which require low energy compared to extension modes. However, fracture propagation limits are encountered when using such flexural modes, preventing the ice from being completely detached from the substrate. This study demonstrates the feasibility of extending the ice detachment area by optimizing the thickness of the substrate. First, the interest and the limits of flexural resonant modes are discussed. Then the de-icing of a simple metallic beam in free conditions using a flexural mode is improved owing to the parametric optimization of the substrate thickness. The optimization is verified by tests on aluminum prototypes. The optimization results are then extended to a clamped composite plate and then to a NACA profile, showing interest in the approach to fully de-ice structures with modes of flexion, even in the case of complex geometries. With this last example, the study also demonstrates the feasibility of electro-mechanical ice protection systems for carbon fiber reinforced Polymer composite structures.

通过优化基板改进共振冰保护系统

电动机械除冰系统是基于冰断裂机制的低能耗防冰解决方案。本文重点介绍共振式电动机械除冰系统，该系统可驱动屈曲模式，与伸展模式相比，屈曲模式所需的能量较低。然而，在使用这种弯曲模式时，会遇到断裂传播的限制，使冰无法完全脱离基体。本研究证明了通过优化基底厚度来扩大冰脱离区域的可行性。首先，讨论了挠性共振模式的意义和限制。然后，由于对基板厚度进行了参数优化，利用挠曲模式改善了自由条件下简单金属梁的除冰效果。通过对铝原型的测试验证了优化效果。优化结果随后扩展到夹紧的复合板，然后扩展到 NACA 型材，表明即使在复杂几何形状的情况下，也有兴趣对具有弯曲模式的结构进行完全除冰。通过最后一个例子，该研究还证明了碳纤维增强聚合物复合材料结构电动机械防冰系统的可行性。

期刊介绍： Smart Materials and Structures (SMS) is a multi-disciplinary engineering journal that explores the creation and utilization of novel forms of transduction. It is a leading journal in the area of smart materials and structures, publishing the most important results from different regions of the world, largely from Asia, Europe and North America. The results may be as disparate as the development of new materials and active composite systems, derived using theoretical predictions to complex structural systems, which generate new capabilities by incorporating enabling new smart material transducers. The theoretical predictions are usually accompanied with experimental verification, characterizing the performance of new structures and devices. These systems are examined from the nanoscale to the macroscopic. SMS has a Board of Associate Editors who are specialists in a multitude of areas, ensuring that reviews are fast, fair and performed by experts in all sub-disciplines of smart materials, systems and structures. A smart material is defined as any material that is capable of being controlled such that its response and properties change under a stimulus. A smart structure or system is capable of reacting to stimuli or the environment in a prescribed manner. SMS is committed to understanding, expanding and dissemination of knowledge in this subject matter.
