inventor e stress analysis

[Ing.Vedder]

Hello to all boys,
I would have some stupid stupid domandina about inventor and his ability to perform work stress analysis...tengo to specify the fact that I am not expert in the matter so do not take for granted anything in your answers.:biggrin:

1)Is it possible to carry out static analysis on assemblies instead of on parts? I need to check a simple flange joint between two beams. I designed the complete axieme of all the bolting taken from the bookcases, I just want to verify it subject to cutting loads and moments that go to act on this joint, how should I proceed?

2)We admit that I have a perfectly flat sheet and want to insert a bond only to a portion of this flat plate (we imagine a circular area in the middle of the slab). When I go into the bonds, how do I make him realize that all the face of the slab I want only my hypothetical circular portion to be bound?

I hope to explain myself, thank you for the help that I know already will not delay to arrive.

1) Axiemi analysis is only possible since 2010. for previous versions comes the axieme in one part (in this case you get a monolithic solid so, if you have material difference between the various parts, it is not okay).
2) to get a region, belonging to a face, on which to apply the force you have to create on this face a sketch draw the circle or rectangle and then use the split command to divide the face. This way you have the little face to apply your forces.

thanks diegus, last night then turning around I found a tutorial suitable for how to apply loads only on portions of areas.. .

As for the aliasys of assemblies, I have 2010 but I have not clarified how to treat the axieme. .
cmq turning I found this simulazoine of a simple set made without a previous version of inventor.

Thanks again diegus,

Hell, I can't run a static test on a set.
I have a flanged joint consisting of two pieces of beams and 6 bolts that connect them

1)I designed my parts
2)I created an asembly file by binding between them the two parts and inserting from bookcase the bolts

The passage I miss now...
how do I switch to a static verification where (I suppose) I will have to tell the program how the pieces are connected together? what flows on what, what is fixed or what is bound to what through bolted or similar union? I hope I've explained

Thank you!

 

[diegus]

the passage that is missing is to define contacts between the parties. when you create the simulation in the window there is the part related to the default contact type setting, which is usually glued. then, once you set the forces, the constraints, the mesh you need to define the types of contacts with the command "calculate deduced contacts" that will only create contacts of the type set in the simulation window. now you should go manually redefinite each relationship between the faces of the components (glued, separation, sliding/no separation, separation/no sliding, etc.). is a long and boring work but necessary to optimize the axieme to be calculated. I recommend you to do tests on simple joints to understand the meaning of the contact types available.

diegus excuses the delay.
I just wanted to thank you for the precious help... a little bit at a time I'm recomponing the puzzle.. .
Thank you very much for your help. I'll be in touch with you soon in case of my troubles.


greetings to all and thanks

Hello to all again,
I think I'm alive because I keep boating with stress analysis and dinamic simulation on inventor but I would like to know if there are guides on these two topics. online there are millions of guides and allrial but nothing that concerns these two specific aspects to me fundamental. Does anyone know how to give me directions? I don't always want to weigh on the shoulders of the diegus in turn for every cockroach

thanks to all of the help, as usual

hi, I suggest you see this page of the autodesk site that I find really useful:http://usa.autodesk.com/adsk/servlet/item?siteid=123112&id=13344407if you keep browsing the various links there is a lot of information

 

[Ing.Vedder]

that you Cool!diegus every post is a lighting!
Thank you very much, at first sight it seems really well done and exhausting.
At the moment I'm trying to get out of a casino where doing a dynamic analysis fixes me a component that I didn't set for fix, but there's no way to remove it from the fixed components...:angry:

still infinitely thanks diegus!

Let's go back to the environment together. the piece you want mobile here actually moves? if you do not move suppress the bond that prevents the movement you have to do (usually it is what you animate to see the effect you do!) if you move then the fact is serious! try to use the space joint between the lever and the base. this joint is used when you have two objects that among them have no bond (e.g. a biglia falling on a floor). I'll take a look.
Hi.

 

[Ing.Vedder]

diegus thanks I managed to overcome this obstacle. I have not been able to continue in my eugubrations on this job, but as soon as I continue, I swear that I return to disturb you and post my cows.

sincerely thank you for your help:redface:
