摘要
利用有限元法对航空发动机某型号压气机叶片的前二十阶固有频率进行了计算，并通过实验测出了叶片的前四阶固有频率，计算值和实测值基本吻合，为进一步分析叶片的振动响应和确定该型叶片的工作范围提供了依据。
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.
