machine fault can be detected by the characteristic changes of the power spectrum of a sensing signal. How to recognize and quanti-tatively translate these signal changes is
therefore
of great importance
A specific variable defined as the expanding coefficient of spectrum which describes the characteristic changes of power spectrum of the signal
is introduced and the fast algorithm of the variable is discussed
It is highly noise proof with good adaptability and requiring less compu-ting time.
