Abstract
The quality of the results of any order analysis depends on the accuracy of the tachometer signal used to estimate the instantaneous rotational speed. There are several techniques used to process the tachometer signal. However, in some cases, there are difficulties in measuring this signal due to physical limitations of the equipment under analysis. This paper investigates a methodology to estimate the instantaneous frequency of a nonstationary signal using the Directional Wigner Distribution. Therefore, the variation of the rotational speed of a rotating equipment can be obtained using only the accelerometer signal, eliminating the need of acquiring the tachometer signal.
