Hello
I need air to make a simulation of the resistance of this product.
Unfortunately with each simulation I have an aberrant result
Do you know where this error can come from?
Thanks in advance

Hello @f.comte69 .
Unfortunately, it's not easy to guess: we don't see how your constraints or their direction are applied... or what you expect to have as a result
It lacks context

The forces I applied them like this
I am trying to find out how the part that is subjected to the forces will react, knowing that the material is galvanized steel and that it supports a 3Kg tank
Hello
Do you want to check or validate which element of your support / with the part connected to the tank?
Kind regards.

Hello @f.comte69
First of all, welcome to our design professionals forum.
Can you specify your version of solidworks
Can you post your ASM using the pack and go, it will be easier to understand and see all the parameters you have used.
I already see something superfluous, namely "gravity" which is absolutely useless as long as you use forces directly and not remote charges or other more elaborate calculations.
Can you confirm that this mini rack is only used for washing.
Given its shape, one might think that it is used for other things elsewhere. 
As our colleague implicitly says @spectrum if these frames already exist, why do you need to do an RDM simulation?
Is it a student exercise??? in short tell us everything 
Kind regards

Personally, I wonder what is bothering about the results obtained? Is it the value of deformation? Is it the deformation itself?
I suppose you put a fixed support under the feet?

Hello
On your image, the result for the constraint is not alarming, it is even very weak.
If it's the visual that bothers you, you can change it in the settings.

Hello
I share the last opinion... we therefore have 20.75 N/mm² of maximum stress for 203 N/mm² of stress of the configured material.
10^6 mm² in one m².
Kind regards.

Personally I'm not surprised by the results, the constraints remain low in the assembly and for the movements it remains quite low since it's on a scale of 371. If it is the displacement, it is easily set in the displacement settings by checking the "actual displacement" box.
Kind regards
Hello, thank you very much for all your answers. I'll try to put a little bit of context. I'm doing an engineering internship in an association and I had to build washing tables, but I didn't do a resistance simulation before the construction. So I know that my products are resistant but my teachers ask for simulations, something that I struggle to do (displacement, deformation)
Car wash V2.zip (1.2 MB)
The product is only used by washing the tanks with a karcher.
Hello @f.comte69
Thank you for these clarifications relating to the legitimate demands of the teaching staff.
However, I don't see the results of your simulation with the ASM attached, so it's difficult to help you.
But from my point of view, there are prohibitive flaws in doing the simulation.
1°) You have 4 interferences between the parts so the software will send you to the Parthenon as soon as the mesh is made.
2°) Your circu 37 profiles which are of the Ø 10 round are tangent on a point. And since you have neither embedded nor drawn a weld, the simulation will only take into account a few tenths of contact, so nothing in terms of strength.
3°) ditto and worse for the "L parts" which have contact only on one point.
4°) It is customary in the trade to make a 3D drawing as exact as possible, especially on contacts between profiles (we can only guess about the skill of the workshop's debuggers.)
BRIEF! repost your ASM by correcting the errors and above all attach the results of your simulation. In the "pack and go" we need to check attach the simulation results.
Moreover, I am not going to add to what my eminent colleagues have said, but from a design point of view I would have solidified the front legs a little.
I would have put a second "34 square profile" between the two front legs (but it's too late apparently)
What for?
Because the people who are going to do the high-pressure cleaning have no reason to be particularly careful (even in a basement) with the building which will be mistreated more often than not. I think that falls when the water jet is on the sides is likely to be frequent.
Kind regards

Thank you very much for your help, I was able to solve all the problems.
We are very happy that you came out on top.
Could you post your ASM and especially the result. It's interesting for everyone.
Kind regards
Don't forget after posting the result to close the topic
