Condition-based monitoring system for rolling element bearing using a generic multi-layer perceptron
(Sage Publications Ltd, 2015-12-01)
Rolling element bearings are critical mechanical components in rotating machinery and fault detection in the early stages of damage is important to prevent their malfunctioning and failure. Vibration monitoring is the most ...
Condition monitoring of structures under non-ideal excitation using low cost equipment
(2017-04-25)
Monitoring the integrity of structures and machines is an evergrowing concern in engineering applications. Better knowledge of structural conditions allows optimized maintenance cycles, increasing the availability and ...
Monitoring of condition of the railway system.
(Association for Engineering Mechanics, 2010-05-31)
The multidimensional monitoring of symptoms applied to railway systems allow to detect and locate the sections of the track (straight and curved) that generate thedecrement of the safety and comfort of the passengers. It ...
Dressing tool condition monitoring through impedance-based sensors: Part 1—pzt diaphragm transducer response and emi sensing technique
(2018-12-01)
Low-cost piezoelectric lead zirconate titanate (PZT) diaphragm transducers have attracted increasing attention as effective sensing devices, based on the electromechanical impedance (EMI) principle, for applications in ...
Assessing the ecological condition of streams in a southeastern Brazilian basin using a probalilistic monitoring design
(Springer International Publishing, 2015)
Conditional maintenance using artificial neural network and vibration techniques to improve production cost-effectiveness
(2008-01-01)
Currently, a number of researchers have been working to understand the health monitoring and damage detection problems. Structural health monitoring (SHM) and damage detection techniques are instrumental for the engineering ...
A synthetic control chart for monitoring the process mean and variance
(2006-04-10)
Purpose - The aim of this paper is to present a synthetic chart based on the non-central chi-square statistic that is operationally simpler and more effective than the joint X̄ and R chart in detecting assignable cause(s). ...
Development of an instrumentation system embedded on FPGA for real time measurement of mechanical vibrations in rotating machinery
(2012-11-23)
The real-time monitoring of events in an industrial plant is vital, to monitor the actual conditions of operation of the machinery responsible for the manufacturing process. A predictive maintenance program includes condition ...
