setup will cost tens of thousands of dollars. But the information it provides is arguably
easily worth the cost for some applications!
If you are interested in finding out more on modal analysis, check out Dr. Peter
Avitabile’s Modal Space articles (the previous images are from this collection of articles).
He has been doing modal analysis for 40 years and “grown up” with the industry; so
finding an expert with more experience than him is very difficult, if not impossible! Brüel
and Kjaer also have a two part Structural Testing document (part 1 is mechanical
mobility measurement; part 2 is modal analysis and simulation). These documents were
written back in 1988; but they are still applicable even today, especially the
fundamentals. The most thorough and modern resource we’ve come across is available
from the Modal Shop, The Fundamentals of Modal Testing.
