【摘要】 将分形维数用于刻划滚动轴承在不同故障状态下表现的非线性行为，进而对故障分类。试验结果表明，滚动轴承振动信号在不同故障状态下的分形维数是不同的，可以将分形维数作为识别滚动轴承故障的特征量。更多还原

【Abstract】 The fractal dimension is applied to describe the non linear behavior of the rolling bearing in the different fault conditions and classify faults of the rolling bearing. The experiment results show that the fractal dimension of the vibrastion signal of the rolling bearing is different for the different fault condition and can be used as the characteristics for recognizing the rolling bearings, fault.更多还原
