摘要：

Fractal geometry is a new method to apply in analyzing fault signals. After researching the characteristic of rolling bearings, a new quantificational definition about fault signals of rolling bearings is proposed. Based on fractal theory and the conception of box dimension it can describe both non-stationary and non-linear signals of vibration signals generated by rolling bearings. Experiment results shows that the box dimensions are different in evidence because of the difference of dynamic mechanism. The fault pattern recognitions of rolling bearings are effective and accurate by the new method of box dimension.
