摘要
自叶尖定时法提出以来,其众多突出的优点使其成为当前旋转叶片在线监测领域中的研究热点。在现有文献的基础上,首先对叶尖定时测量方法的基本原理进行简述,总结近几年国内外在该领域取得的成果和研究现状;然后,介绍几种基于叶尖定时法的传感器和叶片振动参数辨识的新方法,并对其进行分析和比较。最后,提出该领域未来研究的方向和难点。
The blade tip timing (BTT) method has attracted increasing attention in the field of online detection of high speed rotating blades due to its outstanding advantages since it was put forward. In virtue of the published literatures, the basic principle of the blade tip timing method was described. Both achievements obtained at home and abroad in recent years and research situations in this field were summarized. Several kinds of sensors based on BBT method and some new techniques for blade vibration parameters identification were introduced, analyzed and compared. Finally, research interests and difficulty in future study of this field were put forward.
