中文摘要: |
简要介绍了Gabor变换的基本思想,提出了一种新的基于Gabor变换的自适应信号降噪方法。分析了该方法的降噪特性,同时比较了小波降噪和该方法的降噪效果。将该方法用于齿轮箱的故障诊断,结果表明,该方法能够有效识别齿轮箱中的齿轮典型故障。 |
英文摘要: |
The basic theory of Gabor transform is first introduced,and an adaptive noise reduction method based on Gabor transform is presented. Then the de noising results are researched by simulated signals,and the result of wavelet de noising is compared with the adaptive de noising method. At last, this new method is applied to analyze the measured signal from gear box and the result shows this method can diagnose the fault information under strong noise. |
