摘　　要：针对提升机工作时所处环境背景嘈杂,监测得到其驱动电机振动信号中含噪声多,信噪比低,难于根据振动信号诊断电机可能存在的故障问题,提出利用相关差分振子阵列的方法检测提升机电机设备故障。该方法利用相关分析去除信号中的噪声信号,再利用差分振子阵列对提升机振动信号中可能包含的频率信号进行检测,研究结果表明相关差分振子阵列检测方法可以准确诊断出提升机驱动电机内圈和转轴不对中的故障隐患。The hoist works in noisier environment and its drive motor vibration signals contained more noise and lower signal -noise ratio, which makes it difficult to diagnose the motor failures according to vibration signal. In order to solve the problem, the method of correlation differential resonator array for hoist motor equipment fault diagnosis is proposed. The method uses correlation analysis to remove the noise in the signal, and differential resonator array to detect hoist vibration signal which may contain different frequency signals. The result shows that the detection method of correlation differential resonator array can accurately diagnose the hidden faults in the inner ring and shaft misalignment of hoist motor.
