Time synchronous averaging of ball mill vibrations

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.

A Different Way Of Averaging Time Synchronous

I have been using time synchronous averaging in vibration troubleshooting, since 1979, with various 1, 2 & 4 channel RTA’s. Readers may be interested in another application for sync time averaging: 2-pole electric motor vibration analysis, in distinguishing 2xRPM (slightly less than 120 Hz), 2x Line Frequency (~120 Hz), and Ball Spin Frequency (often very close to 2x rpm).

ON THE USE OF TIME SYNCHRONOUS AVERAGING,

Vibration signals of 10secs were collected at shaft speed of 1797, 1772, 1750 and 1730 rpm, using accelerometers attached on the motor housing at 12 o’clock with magnetic bases. The TSAnalyzer performs time synchronous averaging and envelope detection

Vibration Analysis of Rotating Machinery MATLAB &

Time-synchronous averaging is used to isolate vibration components associated with a specific shaft or gear and average out all other components. Envelope spectra are especially useful in identifying localized bearing faults that cause high-frequency impacts.

Experimental Evaluation and Statistical Analysis of

Time synchronous averaging for the extraction of periodic waveforms is a rather common processing method for rotating machinery diagnosis. By synchronizing the signal to the rotational angle of the component of interest (e.g. by using a tachometer reference signal), it is possible to perform the averaging in the angular domain, thus obtaining an angle-synchronous signal.
