Abstract
Contrapose the fatigue life of compressor blades under thermal-vibration combined load, this article is described to carry out the fatigue life test of blades under the thermal-vibration load, the test device is designed in this article, the test conditions are determined, and the test results are analysed to obtain the conclusion that resonant frequency decreases gradually as fatigue life time goes on, and the extent of blades damage could be quantitatively described by calculating the drift distance of resonant frequency. It can also provide data support for life prediction.
