轴流式压气机在旋转失速时 ,对压气机叶片产生振动应力 ,采用单级轴流式压气机试验器进行应力测试。在转子叶片上粘贴电阻丝应变计 ,把试验时所有信号用磁带记录仪记录下来。最后由统计数据得到四条曲线 ,可以看出在失速状态时应力明显增大 ,噪声明显增大 ,旋转失速对整机振动影响不大 ,但在高转速由于失速团的能量增大 ,整机振动明显增大 Axial compressor in the rotation stall, the compressor blades produce vibration stress, the use of single-stage axial compressor stress test. Strain the resistance wire strain gauge on the rotor blade and record all the signals in the test with a tape recorder. Finally, four curves are obtained from the statistical data. It can be seen that in the state of stalling, the stress is obviously increased and the noise is obviously increased. The rotating stall has little effect on the vibration of the complete machine. However, due to the increase of the energy of the stalling stall, Significantly increased
