Description: A fast MATLAB program to estimate the multifractal spectrum of
multidimensional data: Application to fractures
"A MATLAB program based on the Hou algorithm for estimation of fractal dimension and multifractal
spectrum of fractures is presented. The program performance was tested with many synthetical fractals
and fi eld data. Interpolation and sampling effects on the fractal dimension and multifractal spectrum
estimation were also studied. Some common problems related to the fractal dimension and multifractal
spectrum are also discussed.

将齿轮箱振动信号的多重分形特征量作为支持向量机的输入参数以识别齿轮的故障类型。实验结果表明, 该方法在样本较小的情况下能够准确对齿轮箱的故障类型进行分类-Gearbox vibration signal of non-stationary and non-linear, the combination of a multifractal support vector machine fault diagnosis method. The use of multiple fractal theory methods to analyze gear vibration signals, through the analysis found multifractal spectrum and broad-dimensional number as the fault feature able to well reflect gearbox work state support vector machine parameters utilize particle swarm optimization algorithm to optimize and the multifractal characteristic quantities of the gearbox vibration signal as the input parameters of support vector machine to identify the type of gear failure. Experimental results show that the method in the case of a smaller sample can be accurately classify the type of failure of the gear box Platform: |
