Diagnostics and prognostics in rotating machinery is a subject of much on-going
research. There are three approaches to diagnostics and prognostics. These include
experience-based approaches, data-driven techniques and ...
This study develops a novel degradation assessment index (DAI) from acoustic emission signals
obtained from slow rotating bearings and integrates the same into alternative Bayesian methods for
the prediction of remaining ...
The study evaluated bearing damage detection using SVAN 958 and laser. Accelerometers attached to SVAN 958 were
used to measure the radial accelerations from the bearing housing. The laser which is an optical device was ...

The effect of the rotational speed and axial torque on
the diagnostics of tapered rolling element bearing defects was
investigated. The accelerometer was mounted on the bearing housing
and connected to Sound and Vibration ...

This study quantifies whole-body vibration on a range of mine machinery typically used in a South African open cast mine. The ISO 2631-1 (1997) standard was used in the computation of weighted root mean square (WRMS) and ...
Aye, S.A. (Sylvester Aondolumun); Heyns, P.S. (Philippus Stephanus)(Southern African Institute of Mining and Metallurgy, 2011-11)
Vibration levels on a variety of equipment in a South African
opencast mine were measured in this study. The well-established
ISO 2631-1 (1997) standard methodology was used for the
computation of weighted root mean ...
