The FEA "analysis" is laughable. make a pretty picture with no scale for the press, or just not understand how to do FEA? Which is it?
I'm guessing the former. Mike Kojima's articles usually come across as pretty well written.
it is also conceivable that they HAD said information but did publish it at the manufacturers request or chose not to publish it for space reasons or just felt it unnecessary...
FEA has a few uses depends on what they are using it for. I think in the context of the article it serves it's purpose. You can plainly see where the design limitation is in that wheel.
What I would like to see is the constraints and loading conditions, not just the scale.
Here is a link if you want to see some of the work we did back in the day.
Recumbant trike design and analysis
Well, it is obvious to this layman that there wasn't an even load applied to the wheel, I too would like to know what the load and it's vector was. Allow me to manipulate that piece of data and I can make overcooked pasta look super rigid.
In reply to mistanfo:
Had to be some sort of load, or no pretty pictures.
Dropping a load usually does not lead to a pretty picture,

Yeah, looks like they just applied a static load, there's no stress in the spokes at 12 o'clock and 6 o'clock in the picture, just tension and compression at 3 o'clock and 9 o'clock.
I think this is a standard case of 99.9% of that site's visitors not even knowing what FEA stands for. I wouldn't bother explaining something like that either.

Pretty disgusting, really. Obviously no realistic loading or constraining conditions, and yeah, no scale, so pretty little light blue globs could be 200% of the yield strength of the material.
