Doing the FEA but not the manufacturing / testing ...

[321GO]

Hello to you all.

Not sure if this is the right forum for this question though.



What i see alot is that companies outsource the actual manufacturing but wish to keep the design and FEA inhouse.

So there is an obvious rift between the FEA and the actual part, i.e. in the feedback from the testing of the part.

I believe FEA and the actual manufacturing, testing and practical application needs to be integrated.
If seperated, what's the use of the FEA in the first place?

Guys, i'm I missing something here, or do you also think this is not good for local/inhouse FEA

Btw, how is this "problem" solved by FEA consulting businesses? Just wondering..

FEA is dead easy to do remotely from the physical testing. Why do you think it isn't? I routinely pick up physical loadsets that were measured in the USA and do various things to them before they are used to exercise an FEA model built and run in Australia, India or Germany.




Cheers

FEA and testing should be done in one place so that correlation between the two can be more efficient. However, in this day and age, you can do FEA on the west cost and have the test done on the east cost. It would be ideal to have the ME who is doing the analysis present during test so s/he can feel and see the dynamics. Other than that, exchange of data is fine. Manufacturing is another animal. Operation (manufacturing engineers) should be able to create the product separate from Engineering. If there is a procedure that is more sever than what the product was designed then the procedure has to be re-thanked.
