摘　　要：针对煤矿电机设备所处环境背景噪声大,设备故障信号的信噪比低,难于诊断的问题,提出将相关差分振子阵列的方法用于煤矿电机设备故障诊断。应用该方法对煤矿电机设备轴伸端振动信号检测,研究结果表明相关分析可以去除电机轴伸端振动信号中的背景噪声,提高了信噪比,差分振子阵列对电机信号中可能包含的不同频率的信号进行检测,可以准确诊断出煤矿电机不对中的故障隐患,是一种新的煤矿电机设备故障诊断方法。Due to the powerful background noise, the lower signal-noise ratio in mine motor and the difficulty to diagnose equipment fault signal, the method of correlation differential resonator array for mine motor equipment fault diagnosis was proposed, and it was applied to detect vibration signal of mine motor axle stretch end, the result showed that correlation analysis could remove the background noise in vibration signal of mine motor axle stretch end and improve the signal-noise ratio. The differential resonator array could detect the motor signal with different frequencies and accurately diagnose the hidden faults in mine motor. Correlation differential resonator array was a new fault diagnosis method for mine motor.
