Prediction of Defects in Roller Bearings Using Vibration Signal Analysis
Roller bearing failure is a major factor in failure of rotating machinery. As a fatal defect is detected, it is common to shut down the machinery as soon as possible to avoid catastrophic damages. Performing such an action, which usually occurs at inconvenient times, typically results in substantial time and economical losses. It is, therefore, important to monitor the condition of roller beari...
متن کاملBearing diagnostics using image processing methods
In complex machines, the failure signs of an early bearing damage are weak compared to other sources of excitations (e.g. gears, shafts, rotors, etc.). The task of emphasizing the failure signs is complicated by the fact that changes in operating conditions influence vibrations sources and change the frequency and amplitude characteristics of the signal, making it non-stationary. As a result, a...
متن کاملVibration Signal Processing Using Matlab®
Vibration signal processing has traditionallybeen accomplishedusing analog and digital signal analysers, or by writing assembler,FortranorC compiled code. The advent of higher level interpretive based signal processing software products like MATLABhas added a new dimension to vibration signal processing. This paper will outline the applicationof MATLABto analysisof the vibrationfrom rotating ma...
متن کاملCondition assessment of elastic bearing supports using vibration data
Health monitoring of engineering structures has gained a lot of interest over the last few years. Many engineering structures suffer damage and deterioration when exposed to various loading and environmental changes during their lifetime. This seriously affects structural performance and may even lead to catastrophic structural failures. Thus, inspection and testing of structural components for...
متن کاملA One-Versus-All Class Binarization Strategy for Bearing Diagnostics of Concurrent Defects
In bearing diagnostics using a data-driven modeling approach, a concern is the need for data from all possible scenarios to build a practical model for all operating conditions. This paper is a study on bearing diagnostics with the concurrent occurrence of multiple defect types. The authors are not aware of any work in the literature that studies this practical problem. A strategy based on one-...
