| Abstract: | In view of the breakdown vibration in operation as well as the drive source which occurs in vibration movement situation on the screw rod compressor, according to the vibration breakdown circulation steady characteristic caused by breakdown drove the source. Has introduced the characteristic and advantages and disadvantages on traditional, wavelet deafening method using Matlab as well as the emerging wavelet deafening which carries out the new deafening the method, has highlighted the good characteristic of deafening method using the new deafening device. |
