| Abstract: | Melliin Transform is employed to develop the formula of cntinuous wavelet function in frequency domain, and a fast algorithm of continuous continuous transform for nonstationarity vibration signal analysis is pres ented. The paper shows its fundemental principlc, characteristies and application, Its application cffect is illustrated by engineering example. |
