Introduction

Enhance the knowledge level of a group of fresh Mechanical Engineers with reasonable background on vibration, it’s analysis & use as diagnostic tool; imbalance and basic of balancing.

This course provides a detailed examination of the detection, location and diagnosis of faults in rotating and reciprocating machinery using vibration analysis. The basics and underlying physics of vibration signals are first examined. The acquisition and processing of signals is then reviewed followed by a discussion of machinery fault diagnosis using vibration analysis. The course is concluded by a review of the other techniques of predictive maintenance such as oil and particle analysis, ultrasound and infrared thermography with an introduction to automated machine condition monitoring.

Objective

Upon completing this course, participants will be able to:

• Understand the basics of vibration measurement

• Demonstrate the basics of signal analysis

• Understand measurement and the characteristics of vibration signals

• Understand how to use Data Acquisition Equipment for vibration signals

• Apply vibration analysis for different machinery faults

• Apply specific techniques for pumps, compressors, engines, turbines and motors

• Apply vibration-based fault detection and diagnostic techniques

• Diagnose machinery related problems with vibration analysis techniques

• Apply advanced signal processing techniques and tools to Vibration analysis

• Detect, locate and diagnose faults in rotating and reciprocating machinery using vibration analysis techniques

• Identify conditions of resonance and be able to rectify these problems

• Understand the basic advantages of allied predictive techniques such as oil analysis, thermography, ultrasonics and performance evaluation
