摘要
基于叶尖定时测振原理,对利用速矢端迹法分析叶片同步共振幅值的方法做理论推导,建立叶片同步共振的分析模型并进行仿真.将该方法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结果基本一致.
Based on vibration measuring principle of blade tip-timing, theoretical derivation is done to the method of analyzing amplitude of synchronous blade vibration using speed-vector-end-tracking method. Analyzing model of synchronous blade vibration is setup and simulated. The method is applied on a certain model of aerial equipment to do simulation experiment whose result is similar to theoretical model, and the amplitude measured is in accord with the result of strain gauge in general.
