FEA Plate AnalysisMore
Keyboard plate FEA analysis was needed to measure deflection and try to achieve a uniform plate deflection distribution across the keyboard. This was a continuation of the work done on our Iron165 Keyboard. You can read more up on it here and our testing methodology:
https://geekhack.org/index.php?topic=101470.0For the Iron180 I started with the same basic principles but instead of starting from scratch I imported a lot of the design features from the Iron165, added some relief cuts to better suit a TKL and began modeling. The first results were less than ideal, as expected working with a much larger plate. Here are the initial results.

Results had a large range from 0.2532mm down to 0.0990mm. The upper relief cuts needed to start disappearing quickly to even this up.

Much better in the upper left, but bottom row still wasn’t where we wanted it.

Horizontal cuts below the ‘B’ key really helped get them in line. Plus added a lot of cuts between mod keys

Removed more relief cuts from the top, and added a connection in one to lower the right bracket key value. Also added a connection beneath the ‘B’ key but it added way to much support.

More small changes, reverted ‘B’ key connection

More a quality of life, replaced all the ugly cuts at the top with the mod relief cuts, cleaned up more spots.

This was intended to be the final one but I wanted to run more test to see what difference adding some cuts to the number row would make on the alphas below them.

Finalized plate!
