Abstract
Synchronous averaging method is applied to extract the signal attributed from driving and/or driven gear from each other. Some concepts about signal processing used in synchronous averaging method are discussed here. From the results, it is recommended that the length of each block of the signal that will be averaged should be selected to fit with the period of driving or driven shaft revolution. In this case, rectangular window is used instead of the other window functions. Shaft order analysis is applied for extraction vibration components at each shaft order from the vibration waveform. With these processes, the more precision in amplitude and frequency of vibration results are obtained. The effect of the number of averaging is also discussed.
