Optimisation of Bearing Diagnostic Techniques Using Simulated and Actual Bearing Fault Signals

A Comparative Study of the Effectiveness of Adaptive Filter Algorithms, Spectral Kurtosis and Linear Prediction in Detection of a Naturally Degraded Bearing in a Gearbox

“…However, for practical diagnostics, the reference signal is not always readily available. As an alternative a delayed version of the signal has been proposed as a reference signal and this method is known as self-adaptive noise cancellation (SANC) [25] which is based on delaying the signal until the noise correlation is diminished and only the deterministic part is correlated [26].…”

Intelligence diagnosis method for roller bearings using features of AE signal

“…Among them, vibration measurements and analyses are widely applied. Quite a few works have been done in this field [1][2]. However, acoustic emission (AE) can be used as a non-destructive testing method to monitor mechanical events and processes in rotating machinery and diagnose faults during operation.…”

An extensive review of vibration modelling of rolling element bearings with localised and extended defects

“…They modelled the inner and outer rings as rigid bodies, and the rolling element-to-raceway interfaces as [48] and cyclic spectral densities [17,216,217]. The results were compared with experimental data for a 852 bearing where extended faults were etched on both of its raceways, and good similarity between the two 853 results was achieved.…”

“…The main objective of the models, impulse-train [43][44][45][46][47][48][49][50][51][52], multi-body [53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69], and FE models [70][71][72][73][74][75] …”

“…The periodic impulse-train models were extended [47][48][49][50][51] with the inclusion of 1107 the slippage of the rolling elements [48,49], so as to gain close agreement with typical vibration measurements 1108 obtained in practice.…”
