"Take a look at Meridium's Practical Reliability Seminar for a new way to think about reliability.  If you have not registered for the Ultra-Lube giveaway, time is running out. Download Free Acrobat Reader Version 5 for Reliability Reading Room articles.  Read the New Weibull Handbook to learn more about this reliability analysis technique.  New Tips have been posted for your review" 

Register at the Meridium website for all of the above.  Attendance at the seminar is not required for white paper or prize drawings. But, if you do attend the seminar, you will be a double winner because reliability cant just be about maintenance anymore.  A truly effective reliability initiative affects operations, production, safety, environmental and corporate objectives as well as maintenance. Before implementing the tactical (tools and methodologies) phase of your reliability program, it is important to know your ultimate objectives and take a critical look at your current state. Our Practical Reliability seminar, October 8-10 in Houston, will help you assess where your organizations falls in the reliability spectrum. Click here to visit Meridium's website to find out about the Practical Reliability seminar. In just three days, you can discover how to transform your new or existing reliability efforts into a useful, value added business opportunity

Last week we posted the new motor article listed below.  Many of you had difficulty accessing it.  We believe that you must have the latest Adobe Acrobat reader (version 5 and above).  We suggest that you get this free upgrade as that is the format we will be using for future articles also.

Weibull Analysis

Weibull analysis is the world's most popular method of analyzing and predicting failures and malfunctions of all types. The method identifies the category of failure: infant mortality, random or wear out.  Weibull analysis provides the quantitative information needed for making RCM decisions which are often made from a qualitative approach.  Weibull failure predictions are accurate even with very small samples of data.   Weibull analysis calculates optimal parts replacement intervals for minimizing cost.  Weibull analysis is needed for making risk based inspection decisions to take action or defer action on potential failures.

Crow-AMSAA charts, a different use of Weibull analysis, predict future failures, analyze R&D testing, track fleets of repairable systems, and provide the most accurate trending of significant events for management. Both techniques may show either  events or cost analysis.  Crow-AMSAA numbers tell if failure rates are increasing, decreasing, or staying the same with time.  Crow-AMSAA plots are also useful for forecasting safety issues concerning future safety incidents, spills, and other controllable events.

Tip of the Week

Vibration Analysis

The sample rate (the number of samples per second) determines the frequency range.  The number of samples determines the resolution.  So for a given frequency range, a higher resolution measurement takes longer to collect.  And for a given resolution, a lower frequency ranges takes longer to collect. - Provided by Jason Tranter of Mobius, Publishers of the iLearnInteractive Vibration Training Programs
