How to simulate motion-rotation-translation?

I would like to show the motion of this assembly as it goes up, and rotates.  I have no idea where to start.

 

Thanks.

Start by attaching the files here - an assembly without parts is useless.

Sorry, try this.  This might be a little hard to explain what I'm trying to do.

 

Thanks.

Did you attach the correct assembly?

Those parts are not in your assembly.

I renamed them, try this.

 

Thanks.

Renaming files like this is a no-no.

An assembly file (*.iam) is simply a list of hyperlinks to the part (*.ipt) files and therefore if you willy-nilly rename the files the hyperlinks are lost.

 

Use Design Assistant or Vault to rename files.

 

You are missing other parts.

Something has to remove degrees of freedom between these parts.

Without the missing link - it is unclear to me what motion you are expecting.

I was thinking Transistional constraint, but based on the parts you did attach - I'm guessing it might be less complex motion than Transistional.

 

Mate this workplane and axis (additional constraints will be needed), does this get you closer?

Yes, that helps alot, but I'm still lost.  As the round part come up, it needs to rotate around the three holes on the lefthand side.  Basicly rotate 180deg, then the cut needs to line up with  the other center hole.

 

Thanks

You need to add 2D Contact Joints.

Sorry I have been out of town and busy with other projects.  My question is now how do you add contact joints?

 

Thanks.

Still need some help with this one.

 

Thanks.

Hi cwalker41,

 

  JD is correct, you can use 2D contacts in Dynamic Simulation (which is included in Inventor Professional, which you should have with your Educational license).

 

  However, you could also accomplish what (I think) your're after using assembly contact set and drive constraint.

 

  I created a couple of constraints, one that will keep the shaft hole centered in the slot.  The other mates the axis to a plane with will move the mobile part across the plate.  The second one is the one you drive.

 

  If you open the assembly, right-click on Mate:3 in the browser => Drive constraint => press the play button.

 

  Hope this helps...

 

Best regards, -Hugh

I forgot to mention that before you drive the constraint or drag the mobile part, you'll need to activate the assembly contact solver (Inspect tab => Interference panel)
