Get Price2013-4-2 Time domain synchronous averaging is most applicable to situations when measurements are being made on constant speed rotating machinery in very noisy environments. To evaluate the vibration from a motor or gearbox which are engulfed in an environment of high levels of uncorrelated noise.
Get Price2017-11-1 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 of the raw signals by convolving raw signals with a repeating sequence.

Get PriceIn [13] performance characteristics of TSA algorithms were studied and a Matlab code for Time Synchronous Averaging based on resampling the time domain data was given.
Get PriceOne other vibration analysis technique for identifying the root cause of the vibration is called synchronous time averaging (STA). It uses a rotational signal from a roll, pump shaft, pressure screen rotor, or press felt trade line (called a trigger) to synchronize the raw wave form based on position of the rotating object.

Get Price2015-7-27 In this method, empirical mode decomposition, dynamic time warping, and time synchronous averaging are performed on gear vibration signals to detect fault characteristic information. First, empirical mode decomposition is performed on the vibration signal and a series of intrinsic mode functions are produced.
Get PriceThis paper proposes a new diagnostic approach that combines envelope analysis, time synchronous resampling, and spectral averaging of vibration signals to extract condition indicators (CIs) used for rolling-element bearing fault diagnosis. First, the accelerometer signal is digitized simultaneously with tachometer signal acquisition.
Get PriceThe technique is based on analyzing the jerk energy gradient of the synchronously averaged fault impact. The averaged signal is extracted by using time synchronous averaging (TSA) triggered by the fault race frequency (FRF) for the detection task and triggered by shaft speed for the quantifying task.
