| 摘 要： | 在航空发动机研发与试车过程中，曾出现风扇机匣振动偏大且振幅存在摆动现象。为明确故障原因，从机匣和转子的振动特性以及机匣变形等多方面对振动测试数据和信号进行了分析。结果表明：振动故障是由机匣变形引起转、静子间隙不协调导致转、静件碰摩所引起的；在机匣发生局部共振情况下，碰摩形式发生变化，引起振动幅值出现摆动现象。

| Abstract: | The intense vibration and amplitude fluctuation of fan casing occurred during the development and test of an aeroengine.To find the cause,the vibration test data and signal were analyzed for the casing vibration characteristics,rotor vibration characteristics and casing deformation,casing deformation.The results show the vibration result from rub between the rotor and the stator caused by the incompatibility of rotor and stator clearence by case deformation,and the amplitude fluctuation result from changed ... |
