摘要 根据Gabor变换理论,提出了基于Gabor变换的故障诊断技术。根据Gabor变换高质量的时频分布,在时频域中通过时频通域设计时频滤波器,用来提取特定信号分量,滤除时频平面中高斯白噪声。仿真信号验证了该方法的有效性,为机械系统中振动信号的分析与诊断提供了新方法。 A signal processing algorithm was proposed for the fault diagnosis according to the Gabor conversion. Based on excellent time-frequency distribution of the Gabor conversion, the time-frequency filter is presented through the time and frequency domain in the time-frequency domain, to extract specific signal components and filter white gaussian noise on particular time-frequency plane. The simulation demonstrates that the filter based on Gabor conversion is effective in signal processing, and provides a new method to analyze and diagnose vibration signals in mechanical systems.
