Fault Diagnosis Analysis of an Aero-Engine Vibration

对某型某台份发动机在出厂试车时出现的整机振动大的故障现象,进行了振动特征分析;采取排除法进行分解检查和试车验证,证明该振动是由转子不平衡所致。

The engine vibration characteristics were analyzed for an aero - engine that exhibited large engine vibration in the factory test. The disassemble check and test verification of the aero - engine were carried out. By the method of exclusion, the vibration failure was found to be caused by the unbalance of the rotors.
