1989-1-1 Analysis of time synchronous averaging (TSA) indicates the teeth with pitch error. TSA and sideband index (measure of sidebands in spectrum) allows the first estimation of the pinion quality and could be applied for commissioning new pinions and gears, and also in a routine procedure for progressive machine condition assessment.

2021-6-15 Time synchronous average (TSA) is currently implemented in Dynamic Signal Analysis (DSA) mode and will be available in Vibration Data Collection (VDC) mode in a short time. In DSA mode, time synchronous averaging is available for the following spectra: auto power spectrum (APS), cross power spectrum (CPS), frequency response function (FRF), coherence (COH), and octave spectrum

2019-11-6 Synchronous Averaging. Synchronous averaging, also sometimes redundantly called “Time Synchronous averaging”, was discussed earlier as a method of background noisereduction in spectraof complex signals. Now, we will look at it as a means of greatly increasing the information we can extract from the time-domain vibrationwaveform.

2007-3-23 A novel signal analysis technique capable of detecting periodic bursts of exponentially decaying oscillation from noisy discrete-time observations is presented. The time-frequency distribution of the signal is viewed as a series of time signals corresponding to different frequency variables, and each time signal is processed with the technique of synchronous average scanning over a frequency region

Dear Analysts, We are facing an issue on our cement plant. It's raw mill main drive motor of 4300kw. On no load condition, vibration is normal but as the feed come, vibration reaches to 4-6 mm/sec (fluctuating between 4 and 6) and whole vibration is on 85Hz (which is natural frequency of end shield bearing housing as told by manufacturer). According to manufacturer, this frequency is being ...

This paper aims to detect planetary carrier cracks through the vibration sensors mounted on the stationary gearbox housing. The spacing of the planet gears related to the rotating carrier plate is unequal, because of the crack on the planetary carrier. In this paper, the time domain synchronous averaging method is utilized to detect the fault.

2017-9-2 Time synchronous averaging using a tacho pulse from the shaft carrying the faulty gear greatly enhances the fault amplitude above the general noise. Time domain analysis is essential on slow speed gears such as mill pinions, slew drives and the like where the impact of the faulty tooth may occur so infrequently as to not be captured in the time samples for normal frequency analysis.
