Hands-on Workshop on Fault Diagnosis and Signal Processing for Intelligent Fault Diagnostic System

Date: 25 May 2010 - 25 May 2010

Venue: Training Room 1. Level 3, SIMTech Tower Block, 71 Nanyang Drive


This is a practical course on machine condition monitoring and diagnostics, with emphasis on sensing, signal processing and feature extraction techniques, to provide knowledge and present tools for analysing machinery faults. Topics include an overview of condition monitoring techniques, basic vibration theory, advanced sensing, signal processing principles and feature extraction. This short course will provide diagnostic examples and demonstrations using SpectraQuest Machinery Fault Simulators which are able to simulate machine faults such as imbalance, misalignment and different bearing faults. The course will adopt a hands-on approach; with theory/lectures, followed by real life examples, as well as demonstration of novel techniques for fault diagnosis. Equipment used includes machinery fault simulator, multi-channel data acquisition system, diagnosis/analysis software, vibration sensor, current transducer, torque sensor and tachometers.
