| 摘 要： | 利用计算机辅助设计软件UG,建立了发动机压气机转子外物损伤叶片的实体模型;采用有限元分析软件ANSYS对叶片进行模态分析,得到了叶片前六阶固有频率随损伤位置、损伤半径的变化规律。最后,通过涡流激振试验测量相应损伤程度下叶片的一阶固有频率,验证了模型的适用性。所得结论为提高发动机可靠性提供了一定的理论参考。

| Abstract: | Using the computer-aided design software UG,the full-scale model for the aeroengine compressor rotor blade damage was established.Modal analysis was done for the blade by using the finite-element software ANSYS.The variations of the first-six intrinsic frequencies with different damage locations and notch radius were obtained.Finally,by measuring the first-order intrinsic frequencies of the blade under corresponding damages were obtained by means of whirlpool vibration test,which verifies the feasibility of... |
