DMU Kinematics

DMU Kinematics

DMU Kinematics

(OP)
Hey Guys,
     I think the DMU Kinematics module is a really useful tool but no one in my office is using it... mostly because no one knows how.  I would like to spearhead the initiative and learn how to use the tool.  I'm going through the Catia docs and reading a tutorial I found online.  here is my question!

I'm trying to do a motion/interference analysis of a suspension system, seen below.

Now that's a skippered spring bracket suspension.  Within DMU kinematics can I define those springs as springs, and have them twist and contort?  Also, the ends of those springs are not directly attached to anything, they are pretty much floating inside of the spring brackets at the ends.  Can I define some sort of clash and have them distort when they contact the brackets but otherwise move freely?  

Thanks!

RE: DMU Kinematics

NO - DMU Kinematics is for rigid parts only

RE: DMU Kinematics

I think you can make a spring that compresses if you create it with contexual links but for the distort when in contact then you need a FEA solver, saw a demo of the new nonlinear module in r19 that does that, think the trigram was ANL.

Hi, am a V5R18 user and had this problem in some of my early projects, never found anything about this issue. AUTODESK INVENTOR PROFESSIONAL seams to do the trick though: http://www.youtube.com/watch?v=R4Ui27FU2qM&feature=related I'm not telling you to embrace the idea of using it but it would be nice if some one came with an answer to this topic for Catia.  

RE: DMU Kinematics

WHAT?  Rigid parts only?  I'm assuming you mean for showing movement between rigid parts only....

FEA solver?  Do I need to get some sort of a Catia plugin?  Do you have a link?

YES!  Excatly what I want to be able to do zyx82!  I want to be able to do almost exactly that with Catia.
