cam simulation in ansys

[enrico1979]

Hello everyone
I wanted to ask if you knew what kind of contact I have to select between valve and cam.
I'm talking about the transient module.
I also have to insert a call spring (not exactly how to do it, but I think I can get out of the online guide or not?? ).
I've inserted a song between the two bodies of frictionless type at the moment.
What do you say?

any good tutorials for that ansys modulep??? ? ?

starting to analyze a transient cam is not the easiest and immediate thing there is! do the analysis with the classic or with workbench?
If geometry allows you to start with a 2d analysis.
However for this kind of problem the right software I don't think is ansys but better any multibody analysis software with rigid bodies (adams, lms virtual motion, working model 3d, simpack, recurdyn and others): in fact in the case of analysis of cams the contact is almost always hertzian with negligible deformation of the bodies.

Hello stefano.

thank you for the advice (you have already come to my help).
with pro and the contact force I use it dynamically to deduce and follownd with much
patience driving ansys I think I can solve my problem (by the way I use it
wb )
on other software, I do not know them (if not to say ).
I know a little patran, so I think I'll throw myself up adams.
Since there are, but for static analysis patran you feel more reliable than ansys (wb)?...

 

[stefano.garbin]

Patran is a pre/post.
the solutor is nastran and is worth as much as the ansys solutor as reliability.
results must be equal!
Maybe in the creation of the models there is who goes better with wb, who with patran, who with femap... I know and use ansys, the others barely "mostic" them.

 

[enrico1979]

Yes, of course.

Sorry about my inaccuracy.
By the way I looked at adams and it would certainly be ideal to solve the problem of the cam I raised, but in the company I would be picked if I advanced a claim to buy more licenses.

to the next
