摘要
采用激光全息干涉法对某型发动机一级压气机盘进行振动试验研究,在0-15 000 Hz频率范围内获得了7个振动模态的静频及振型,并根据试验结果研究该轮盘的行波振动,分析轮盘的共振特性及临界转速。
A laser holograph interference method for research on vibration test of first class compressor＇ s disk is used. The static frequency and vibration model of seven vibration mode in the range of frequency 0 - 15 000 Hz are obtained, and based on the results of the test, the constant wave vibration of the disk is studied, and the character of resonance aod critical speed of the disk are analyzed.
