Fractal Analysis on the Vibration Signal of the Diesel Engine

摘要：

The wavelet fractal spectrum was brought forward by combining the wavelet and the fractal theory. The paper divided the vibration signal into different frequency segments, then reconstructed the signals respectively, and calculated the correlation dimensions of signals in each frequency segment, drew curves. The correlation dimension calculated by the method can reflect the system motion state more correctly and reliably.
