摘要
基于叶尖定时测振原理,设计了用于叶尖定时的光纤束式传感器,并对速矢端迹法叶片同步共振的分析方法做了理论推导以及对测量过程做计算机仿真。将该方案在某型号航空设备上进行模拟实验,分析结果与理论模型相符,所测幅值与应变片测量的结果基本一致。
Based on vibration messuring principle of blade tip-timing, fiber-optic bundle sensor used as blade tip-timing is designed. Theoretical derivation is done to the analyzing method of synchronous blade vibration by using speed-vector-end-tracking method,and so is the computer simulation to measurement process. The method is applied on a certain model of aerial equipment to do simulation experiments whose result is similar to theoretical model,and the amplitude measured is in accord with the result of strain gauge in general.
