gas - generative assembly structural analysis

[Pierandrea58]

I should make a structural analysis of the cinematism of a suspension of a mtb
until now I have done simple analysis of parts, but never of products;
Have any of you already done so and could you give me a tip?
especially as regards the connections between the various parts, for example I do not know how to simulate a joint type pin.
Have you ever done anything like that?
Thank you.

Has anyone ever needed structural analysis in an assembly?
I don't believe
Did I miss threads?

Hi.
Unfortunately, I'm not up to help you.

try to see in the online help of catia v5.
It is well done and you will surely find some ideas.

other possibilities search the web

I would do so a first structural analysis:

I hope it's not a festry.
for a deeper analysis would serve a software with the simulator I believe.

Yes I could schematize it, break down forces and analyze individual components
but I would like to do it in the axieme also because so I was asked (it is more scenic)
Thank you
I will let you know once

Hi. I watched it fast and maybe I'll give you the wrong information.
but this video seems to me fem made on a set
fem on together

Yes, but maybe you're helping who uses your own sw.mi seems to understand that this is a problem related to a poor knowledge of a specific sw, more than anything.

Okay.
done
i promised you i'd update youthank you.

Do you have a procedure to advise and where you might have taken inspiration? tutorials, books?

years ago, several, I had retrieved a manual to start with the fea, now if I wrap myself up something I ask for help to the right and miss, after having tried them all
in this case I took inspiration from a pdf I had downloaded in the past, there I found the answer.

Does it seem like you don't want to share it? :

As we know the world of finite element analysis is very vast and complex, and to be able to conduct accurate analysis it serves a high degree of specialization. However, today's tools give designers the opportunity to try in fem analysis, and I remember not only "traditional flam" (see eg. methods implemented by Altair-simsolid and ansys discovery) through sw or additional modules integrated into the cad environment, with increasingly user friendly interfaces.
always depends on the type of analysis you have to do, the possibilities of the tool and the degree of preparation of the user.
contacts, in this case, for example, how did you manage them? have you predicted a non-linearity of the same or not?

Mah. they all look like hinges, in reality there will be bushings and/or bearings.. I don't think he's predicted friction, linear or not. I would see it as a weighting of the simulation quite unjustified since there are no considerable streaks that can change the state of stress. will have inserted ideal hinge bonds that discharge into shared knots horizontal and vertical loads and so on..
rather he said that we are seeing a suspension, so I imagine that in reality this together is a cinematism with at least one degree of freedom. . What is wrong with a static structural analysis that requires an isostatic system. I'd like to know how you handled this. because you can also transform each joint into an ink, but then make the structure strongly hyperstatic, start transferring moments where you should not and overestimate efforts

you misunderstood, I just answered your question
I'll coach you.

in what you see are hinges, but there are also links with screws that, in the image, are not seen and in that case you must specify the preload

Thank you very much
