Designing and Operating Rotating Machinery Free from Vibration Troubles Based on Case Studies

Abstract

This paper presents three vibration-troubleshooting case studies of actual machinery, illustrating a practical method not only to fix or prevent similar problems but also to study how to design and operate machinery free from vibration troubles, based on unique analyses of these case studies. The analyses focus on the initiators that triggered the chain of events leading to the eventual problems and some human factors involved. Understanding only the relation between direct cause and effect won’t suffice to prevent recurrence of same or similar problems, but understanding the total process from the initiator to the final problem inclusive of human factors is much more important. Creating and building up databases consisting of similar case studies with the unique analyses incorporated will definitely contribute to giving birth to vibration-free design and operation methodology.
