Last month, I gave a talk at ESTECH 17 to present some of the core ideas behind the "temporally-informed" techniques for developing meaningful environmental vibration datasets. Here are some excerpts from that discussion about using statistical descriptors in evaluating micro-vibration environments.
I've previously discussed temporal vibration survey methods and the interesting -- and very useful -- statistical perspectives that can be extracted from well-crafted datasets. Now, these methods are being drafted into IEST's recommended-practices document for vibration evaluations in critical environments like laboratories.
I think this is very valuable, because there are myriad ways that temporal effects have been under-appreciated -- with regard to both risks as well as opportunities.
