Measuring Vibration Analysis Program Effectiveness - A Different Kind of Yardstick

by Brian Baldwin

One of the more common challenges for any predictive maintenance (PdM) program is to come up with definable and measurable parameters that tangibly identify the value of the program.

Vibration vs. Ultrasound - Two Techniques to Consider in CBM

by Jason Tranter, Allan Rienstra and Tom Murphy

If someone tells you there is only one RIGHT way to do something - you should be highly dubious! As a result of the positive reader response from "RCM vs. FMEA - There Is a Distinct Difference!" (Dec/Jan 2013), Uptime magazine has invited several subject matter experts to write short, related segments that allow our readers to consider alternatives or options when approaching maintenance reliability improvements. In this issue, we examine two popular condition-based maintenance practices and applications — Vibration and Ultrasound.

Book Review: Case Histories in Vibration Analysis and Metal Fatigue For the Practicing Engineer

Of course, we could have made good use of such a book decades ago. Granted, we have since had access to several good vibration texts by authors with notable academic credentials. Some of these books were based on good course notes and then neatly expounded theories of obvious importance. However, while some of these texts moved on to combine theory and practice, they often fell short of satisfying the true needs of industrial audiences. In clear contrast, Case Histories in Vibration Analysis and Metal Fatigue For the Practicing Engineer by Dr. Anthony Sofronas easily manages to meet these important needs and criteria.

Understanding Why Structural Parts Crack

by Ralph Buscarello

In the April/May 2012 issue of Uptime^® magazine, an excellent article showed the different types of cracks that form in places due to what most engineering articles refer to as metal fatigue. The following article is written by a vibration specialist who claims there is no such thing as metal fatigue, but instead cracks form due to reversible stresses, reversing from tension to compression and back again, at the node of a resonant part.

Where Does Twice-Line-Frequency Vibration Come From?

An hour long presentation by Jason Tranter, Managing Director, Mobius Institute

Have you ever wondered where the twice-line-frequency peak (typically 120 Hz or 100 Hz) comes from in the spectrum? It can indicate a fault condition, and it can be confused with other fault conditions - and it can mean absolutely nothing! In this presentation we hope to clarify two issues; why does the peak appear at twice the line frequency, and which faults are indicated by the appearance (or growth) in the peak at that frequency. In addition to understanding the origin of the twice-line-frequency peak, you will learn a little about magnetic fields and how three-phase induction motors work. As always we will use 3D animations and simulations to make the topic easy to understand (and interesting to view).
