structural analysis bracket on frame

[damo84]

hi to everyone, I write today for the first time on this forum.
I’ve been using solidworks simulation for a while, but often I’m afraid not to apply the constraints properly.

I give you an example to ask for an opinion from the most experienced.

I must check if the bracket represented in the figure resists a certain load (red arrow).
the frame to which it is fixed by bolted coupling is only bound to the sides (green signs).
practically this frame is recessed to the wall and fixed with mortar to the sides.
the solidworks course told me that for the purposes of calculation time it is important to simplify the model. I do not know how to simplify it further given the side constraints of the frame.

I would make a meshatura on all the axieme, a little coarse, with refinements on the bracket and next area to the bolt attack.

What do you recommend?
Thank you very much in advance

I wouldn't put everything together. is the frame subject to stress? because if not so, consider only the framed bracket, the rest erase it (among other things seems a simple plate subject to bending). depends very much on what you want to find, images you need to check that bracket (or need to size bolts? )

no frame is recessed into the wall. my doubt is that the frame sheet, which is bound only to the sides (with the mortar) but not in the back, being of thinner thickness of the bracket, under the weight deform or tears.
In fact, I thought I didn't meshare everything... but I don't know how to assign the constraints to the frame, since the back is just leaning on the wall and I presume it will be a little under load.
Thanks again

I'm sorry, but I'm not getting the problem. I would win the parts in yellow and leave the back free. As for simulation I would recommend you try to consider only the frame and see what is the order of magnitude of deformation. in practice considers that force and its moment of transport.I would incitely approximate everything with shell elements through ansys or other programs but also ok with 3d elements.
if you want to check also the bracket you can consider it as framed at the end and do not consider the frame (at first approximation). If the tensions are far from the critical values I would feel satisfied.

in general frame structures of this nature are typically represented with beam elements and shell, which are also in solidworks simulation. On the other hand, the use of this model allows you to fully represent the axieme without weighing the calculation, possible contraindications could be related to overlaps and monolateral constraints requiring a minimum of attention.
you can create a dedicated surface model, which I recommend, or use the "automatic" tools of solidworks, which still require an ad hoc modeling.
always in general it is more correct to represent with mesh dense the areas of interest and mesh rada the "contorn" than not to represent it.
Good job.

p.s. on the back wall, it would be a unilateral support if it is physically supported in contact with the wall, but if the detached mortgage and then free take a hiring in favor of safety.

thanks guys for the support. I would never have thought that from a simple forum you could learn such technical notions.
possibly week prox put some photos on how I bound it, just to make you participate.
Thank you again! Good weekend

simple?
I wouldn't say, this is a serious forum!

Yes, it is! is a forum with steel attributes!!!! :
