压电陶瓷布局对除冰效果的影响研究

用仿真与实验的方式研究了压电陶瓷除冰技术在复合材料上的应用。通过有限元仿真研究了在能耗相等的前提下压电陶瓷布局（数目、间距）对除冰效果的影响，并进行了冷环境下除冰实验。仿真结果表明:按合理的布局方式，将尺寸较大的单块压电陶瓷分成尺寸较小的多块时，会有比大尺寸单块压电陶瓷更好的除冰效果；随着压电陶瓷间距的减小，除冰效果进一步增强。实验结果表明:增大压电陶瓷输入功率可以较大程度缩短除冰时间；将尺寸较大的单个压电陶瓷分成尺寸较小的4块后，相同能耗下除冰效果增强；减小压电陶瓷之间的的间距后，除冰时间进一步缩短。

Research on the influence of the piezoelectric ceramics layout on de-icing effect

The piezoelectric de-icing method is studied by simulation and experiment on a composite plate. The effect of piezoelectric ceramic layout (number, spacing) on the de-icing effect under the same energy consumption is studied by finite element simulation. The de-icing experiments are done under cold environment condition. The results show that when the piezoelectric ceramics with larger dimension are divided into smaller pieces according to a certain layout, the de-icing effect becomes better than that with large size single piezoelectric ceramic. As the spacing of the piezoelectric ceramics decreases, the deicing effect is further enhanced. The experimental results show that the de-icing time can be greatly shortened by increasing the input power of actuators. After dividing the large piezoelectric ceramics into four smaller ones, the de-icing effect is enhanced with the same energy consumption. The de-icing time is further shortened after the spacing of the piezoelectric ceramics is reduced.
