【Abstract】 In this paper,it will be introduced that the theory of the property of time-frequency analysis characteristic and application of wavelet analysis.Take the vibration signal of reciprocating(QD85) compressor’s start and stop state for example,the paper fully illustrate the methods of how to deal with the transient signals based on wavelet analysis.It was proved that the wavelet analysis was effective and practical on transient signal.更多还原
