Hey, guys.
I wanted a tip from you....
are at the grip with a static analysis of a canopy (dim. 6000x2200 mm) on which a person must be able to move (healthy and only for maintenance of other systems attached to the wall that also supports the canopy. such plants do not weigh on the roof).
the canopy consists of 3 mm aluminum panels supported by aluminum profiles placed in the sense of width, then about 2200 mm long, and 500 mm spaced.
according to what I was required one of the resistance tests that I have to verify is that on the roof must insist a load of 300 kg on a surface that is 600x300 mm.
Now I have two questions to ask:
1) to do the analysis of the required test I generated a cad model in 3d where in the aluminum sheet I obtained a small surface of the size 600x300 (so as if the aluminum canopy had a sort of rat) so that then apply the force of 300 kg only on this surface. In your opinion I did well to act like this or is there a way to make a force act only on a portion of the surface and then eliminate this "roup"? In fact, it seems to me a somewhat difficult solution, since then there are concentrations of efforts on the contact edges between the two plates which should not be there. the contact I imposed between the two plates is "bonded".
2)The other question is about meshatura. I usually carry out an analysis with convergence to ensure myself on the goodness of analysis and model in general, but this time I have problems because of some point of singularity so I do not reach convergence and the same workbench recommends me to use a direct solution. according to you with what criterion I have to set the size of the mesh considering the size of the roof.
Excuse me, I know this may be a trivial question, but it's the first time I happen.
I'm sorry if I've been too long, but I've been trying to explain to myself.
I hope you can help me. Thank you.
