This article is a vibration case history using Operating Deflection Shape (ODS), Experimental Modal Analysis (EMA) and Finite Element Analysis (FEA) tools and computer animation techniques to solve difficult rotating machinery problems.

Based on my experience there are very few experts that specialize in vibration analysis of piping and plumbing line applications. At Full Spectrum Diagnostics we get our share of piping problems, but we really can’t consider ourselves experts. With piping problems we delve into a world of “rules of thumb,” “trial and error,” and “tribal knowledge.” Now, with that said, let me set the table with some of the complexity associated with this type of analysis.
First of all, piping and plumbing lines will vibrate.
