| Abstract: | In view of the actual test item,introduced the hardware composition of the signal gathering system and the signal gathering method used in the roller grinder vibration measure.Summarized the vi- bration signal analysis theory and the method.Analyze the grinder vibration signal based on wavelet trans- form.This method can give attention to the frequency characteristic of both high and low frequency band. It makes the eigenfrequency exacter,and then makes fault diagnosis even more reliable. |
