【摘要】 从分形原理出发 ,提出了非线性机械设备系统信号的分形计算维数的概念。将分形计算维数概念与多层感知器神经网络结合 ,建立了机械设备的分形神经网络诊断方法。通过对滚动轴承系统实例诊断获得了较为准确的模式识别的结果。更多还原

【Abstract】 In the paper, fractal calculating dimension, which is based on fractal theory, is put forwards. Combining fractal calculating dimension with multi layer neural network, a diagnosis method named as fractal neural network is built. Good result is tested and verified through roller bearing diagnosis example.更多还原
