Electroni box modal analysis

[PdorSpa]

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?

"Vibration Analysis for Electronic Equipment" by Steinberg was a popular one when I worked in that area. However, I don't know if there will be anything specific to a box.

Thanks, I will check it

I did a modal analysis of an electronics unit with (tight) slip fit pcbs into partial edge slots in the housing sides and got good results using DesignStar 2007.

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.
