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

  • 摘要: 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。
