Vibration Monitoring System: Improved Reliability, Decreased Maintenance

SAN DIEGO, Calif. - Initial results of a two-ship pilot program show an estimated cost avoidance of $170,000 per ship and more than 1,000 annual man-hours. This pilot program is a Surface Force initiative to improve equipment reliability and to reduce maintenance costs utilizing a new vibration-monitoring module. The results also suggest that time spent in port for maintenance will be reduced significantly. This initiative is another example of how Naval Surface Forces (SURFOR) partners with other organizations, such as Naval Ship Systems Engineering Station (NAVSSES) Philadelphia, to improve warfighting readiness.  

Visual Acoustic Analysis Ends Super Calendar Mystery

by Daniel T. Ambre, P.E.


This article shows an interesting example of how Acoustic Analysis methods were used to solve a stubborn vibration problem where Experimental Modal Analysis and Operating Deflection Shape Analysis fell short.

Using Vibration Monitoring Equipment For OTHER Functions

by: Steve Goldman, P.E. - Author of Vibration Spectrum Analysis

Introduction:

In recent years, it has become rather common for large and medium sized facilities to begin predictive maintenance programs employing narrow band FFT- based vibration analysis equipment. The cost savings involved in this sort of quality predictive maintenance program easily justifies the ten to twenty thousand dollar cost of the data gathering box and related software.

Why you need Continuous Calibration

by Brian Graney,

Single point calibration is not a calibration at all. It is a sensitivity check at 100 Hz. An accelerometer is a dynamic sensor therefore it is required to have its sensitivity checked over its entire frequency range. There are two basic methods for doing this.

 

How is Machine Vibration Described?

By Commtest Instruments

To analyze the condition of a machine you first need to accurately describe the behavior or symptoms of the machine.

How can vibration symptoms be described accurately?

How do vibration analysts describe the condition of a machine?

In this section we present the basic methods of describing machine vibration.

After reading this section you will:

  • Know the two most important methods of describing machine vibration
  • Understand the term 'amplitude'
  • Understand the term 'frequency'
  • Understand what a spectrum or waveform is

Vibration Analysis of Wind Turbines

by Jason Tranter

Wind turbines are dotted across the countryside, seaside, and even offshore. Many believe they are the answer to global warming and stopping the reduction of fossil fuel reserves. Whether you enjoy seeing them on the horizon, majestically spinning in the breeze, or believe they disturb the previously unspoiled landscape, for all of us in the reliability and condition monitoring fields, they pose a new challenge - we have to keep them turning!

 

A Tough Diagnosis - The Saga of the Never Ending Problem

by Greg Davison

You are often told that there is never just one problem with a machine. My very first vibration class taught me that a phase and magnitude vector was a combination of all the vibration from all of the forces acting upon the machine. Likewise, a spectrum also contains all of the frequencies from all of the forces acting upon a machine. So, it is never just imbalance, or just misalignment. It is always some combination of many forcing frequencies. This is precisely why wall charts and cookie cutter solutions do not always work. What follows is a story of multiple problems of mythical proportions.
