Vibration Based Maintenance

Vibration Based Maintenance

Holiday Inn Hotel, Bandung | Nov 30 – Dec 4, 2009 | Rp.8.450.000,-

INTRODUCTION

An application oriented program for industry, which aims to convey the latest thinking and best practice of machinery vibration monitoring and analysis via lectures and case studies. Industrial case study examples are used throughout the program to emphasize key points and to underline the relevance and applicability of the topics being addressed.

The program gives a detailed treatment of the detection, location and diagnosis of faults in rotating and reciprocating machinery, using vibration analysis.

COURSE OBJECTIVES

After attending the program Participants will:

  • Have a detailed understanding of the measurement and characteristics of vibration signals, and the ways in which vibration data can be stored and represented
  • Have acquired a knowledge of vibration-based fault detection and diagnostic techniques, and the practical implementation of these techniques
  • Have the knowledge to assess accurately machinery conditions, and to make detailed and reliable diagnoses for a range of common machinery and component types

TRAINING METHODOLOGY

Participants will learn by active participation during the program through the use of program materials, software demonstrations, hands-on experience of vibration analysis software tools, group exercises, and discussions of �real life� case studies in their organizations.
