| Abstract: | he first 20 steps of the inherent frequency of the blade in a certain type of air compressor on the aviation motors was caculated with FEM method.The first 4th step of the inherent frequency of the blade was measured through experiments,and the caculated values are consist with the measured values.It provides basis for furthur analysising the vibration response and determining working range of the blade. |
