Simulating the feel

[csk]

Hi!

I need to know if anyone has used FEA to simultae the feel of a product (for example closing of a cell phone) etc.

Can I use NHVS analysis in anyway to get started?

Any tips are appreciated!!!

I don't think the that the big trick is utilizing FEA for this; rather the big trick is trying to quantify 'feel' (i.e. what parameters describe good 'feel' vs. bad 'feel' -- acceleration?, jerk?, others?).
If one knows how to quantify this, then numerical simluation can be done. I know people in automotive who have quantified 'good' door handle opening behavior and then successfully simulated it (similarly I am familiar with people quantifying 'good' door slam based on door excitations).
If the reality can be quantified, then the numerical simulation can likely be tied to it. Unfortunately, objectively quantifying these things is very difficult.

Brad,

Thanks for your reply on "Simulating the feel". Is it possible to get in touch with the people you know to get some more information?
Thanks,

I wish I could give that to you; however the work was proprietary within their company, so they cannot reveal those details. Also, due to this there were no publicly-available reports issued for their work.

I would recommend searching through SAE's papers. I would expect somebody would've published something along these lines.

Sorry that I can't be of more help.
