Hello, I am making an imortant research and I wanted to use stress analyse. I watched a lot of videos, but I can not get it to work
Any idea how to fix it, can somebody help if I send him files ?
I also attached a picture of problem

Firstly, your assembly is not fully restrained so I doubt your component contacts are correct/accurate.
Secondarily, you have only global bonded contact set up so I doubt your model is set up accurately in simulation.
I can't tell if your boundary conditions are correct - that's up to you. However, you will have to at least check for interference in the assembly mode and correct those errors before you can begin to mesh the part.
you can also pack and go your models to a zip file and post at the top right
but this looks like a problem with your modeling and then BCs.
I would recommend starting simpler, one or 2 parts and adding them one by one with a simpler gravity load until you get the hang of things.
Well I tried to restrain them fully, but I can not get it to work, if someone could take a look at the solidworks assembly file, I would be super grateful.

I looked at your assembly, it hasn't been modeled correctly. First off, lose the screws & nuts, they don't apply to the FEA. Use split surfaces if you really want to capture the restraint of the 'bolted' connection. Second, design the bracket that fits on the hub 'below' correctly to match the curve or however it is actually attached.
did you start with one part at a time?
start with the part that will be fixed
run with gravity
add another part
and on and on until you have the full model
but like james says, you might need to do some model clean up first
Did you ever get back into the assembly of the item to check interference? Did you track down each one and correct it? I think there were only a handful of them as I recall so it isn't that big a job.
Remember, GIGO - sloppy models lead to sloppy FEA results.
