Electroni box modal analysis
Electroni box modal analysis
(OP)
Hello,
I made a modal analysis in Catia of an electronic box, but I would like to compare my results with a hand calculation since I'm affraid they make no sense... could anyone recommend me a book where I can find a method to get the natural frequencies?

To get good agreement with the empirical results I had to pay attention to the fastening (restraints) of the pcbs.
They were modeled with sliding restraints rather than fix edges that the tight fit could imply. The unit had 4 pcbs of about 4 by 5 inches in machined enclosure sides that were bolted.
The lowest modes were the loaded pcbs.
The enclosure fasteners are always the difficult area to model.
