摘要
基于某轴流压缩机第1级动叶片,在精确建立其几何模型的基础上,通过有限元仿真方法提取了前10阶固有频率及模态振型的计算值,然后通过试验测试方法对其进行了模态测试,得到了前10阶固有频率及模态振型的实测值,并将理论计算结果和实际测试结果进行了对比。
Based on accurate geometry model establishment of the first rotor blades of an axial flow compressor, the first 10 stages natural frequencies and modal shapes have been calculated by finite element method. And the modal test has also been completed by experiments to measure the first 10 stages natural frequencies and modal shapes. And the comparison between the values of the calculated and the measured has been completed.
