摘要/Abstract

摘要： 针对对称差分解析能量算子在高幅值振动干扰频率影响下性能较差的不足，在对称差分解析能量算子的基础上提出了一种改进的解析能量算子.该能量算子改用高阶对称差分序列替代对称差分序列以达到提高信号干扰比的目的，从而提高在高幅值振动干扰频率存在下提取故障特征的能力.此外，为了防止能量出现负值，该改进的能量算子采用了绝对值对其能量表达式进行加权处理.通过模拟实验证明了该方法在抗噪和抗振动干扰方面的优越性，及其它的非负特性.最后将其应用于真实轴承故障数据，发现该方法可以在恶劣工况下提取出故障特征频率.

Abstract: Considering that the inadequacy of the inferior performance of the symmetric difference analytic energy operator (SD-AEO) technique in the presence of vibration interferences with higher amplitudes,an improved analytic energy operator (AEO) based on SD-AEO is proposed in this work.This proposed energy measure takes advantage of the higher-order symmetric difference to substitute the symmetric difference for the sake of boosting the signal-to-interference ratio (SIR),which can enhance the ability to detect the weak fault signal in the presence of vibration interferences with larger magnitude.Furthermore,the energy transformation of this proposed energy operator is weighted by absolute value to prevent the negative values in the transformed signal.Under the simulated tests,the superiority of the immunity to intensive noise and interferences as well as the non-negative property is demonstrated.Finally,the proposed energy detector is applied to the real-world data measured from the defective bearings,and it is found that this proposed fault detection tool can successfully identify the weak fault signatures under a severe working condition.

Key words: bearing fault signature detection, higher-order symmetric difference, analytic energy operator, non-negative property
