摘要
利用有限元软件对某航空发动机高压模拟转子进行了自由模态分析,并采用锤击法开展了相应的自由模态试验,获取了多种状态的模拟转子模态频率及模态振型参数,通过仿真分析与试验结果对比分析,为航空发动机高压转子的结构刚度设计提供了参考。
Free-free modal analysis and stamping modal analysis was applied on a high-pressure simulated rotor of aero Engine. Emulation analysis and the test results of modal frequency and modal shape offer some reference to structure design on high-pressure rotor of aero Engine.
