| Abstract: | The paper applies the multi-fractal and renyi dimension to describing the properties of signal,and takes the renyi dimension,renyi dimension chart,sensitive dimension of signal for properties vector.As a distinguish factor,the dimension relating degree is put forward in the multi-fractal and renyi dimension diagnosis method for mechanical fault.The method is used to distinguish a crack fault of circular plate with satisfied result. |

| Keywords: | multi-fractal renyi dimension sensitive dimension fault diagnosis |
