The calculation formula of general dimension least square method is presented by applying the multi-fractal theory and the general dimension calculation sample analysis of sine signals is achieved. The general dimensions of measured time domain signal of rolling bearing are calculated and analyzed, the sequence value of general dimension is obtained, the box dimension, the information dimension and...
The multi-fractal theory is applied for proposing the calculation formula of general fractal dimension according to the characteristic of rolling bearing vibration signal. The general dimension of measured non-stationary time-domain signal is calculated and analysed, the box dimension, the information dimension and the correlation dimension are obtained. Combined general dimension sequence value and...
