Re: Creo3 fasteners & 'carries shear'
I saw this and got my calculator out .... I was looking for the lazy way out similar to a WF4 check box. If I recall correctly, getting a spring element to behave exactly like a beam element isn't...

Hi Don, Then why can I add it to one part, but not the other two? I'll assume it has somethign to do with adding eh reagion to eh first part, the grounded part, the 'default' constrained part.

OK, I've changed those contact areas to 'rigid links' And I seem to be back to where i was a few days ago when I first started (when I was playing with this model as 'shell elements' / shell pairs.')...

Paul, Is it the same part that you are trying to perform the function too?Are the parts mirrored? There may be an external reference that is only available at the assembly level that is interfering...

Agreed, springs aren't the same. Mind you, everything is an approximation and in my case, carrying shear is not good. I thought the change over was with the intro of Creo1.0
View ArticleRe: What constraint do I use for a component only held by friction?
Apologies for the confusion; my fault. I was asking a question mechanism dynaimcs analysis, but thank you everyone for your help. I didn't see a category for Mechanisms so I posted in Simulate with a...
View ArticleRe: What constraint do I use for a component only held by friction?
I used a "planar constraint" with friction applied to the rotational axis (this is done in assembly mode, edit the assembly constraint definition and then you can enter/edit dynamic properties for each...

Hi All, OK, here's the senario. i have a door hanging by one hinge, the top hinge. Obviously gravity will act on teh door, and pull the door downwards & inward (so that the door's CoG falls under...
View ArticleRe: How to model a gravity load
I'm not entirely clear on the scenario you're trying to model, and there is a couple different way you can do this; which is more appropriate depends on the specifics of your system and the results...
View ArticleRe: How to model a gravity load
Paul, Whenever a gravity simulation is used, I would highly recommend verifying the total weight of the model. I use the IPS system of units and 1g = 386.4 in/sec^2. After you build your model, run a...

Agreed, springs aren't the same. Mind you, everything is an approximation and in my case, carrying shear is not good. Exactly; so while a spring might not behave exactly like a beam element, you can...

Paul, Are you allowed to upload the model and some screenshots of the real-world problem along with a description of the problem (loads, constraints, region (s) of interest)?
View ArticleRe: How to model a gravity load
Thanks all, Yes, i'm playign around with Simulate. The books & lessons only show you a few ideas, and they pretty much walk you thru the exapmples. I wanted to try somethign on my own. I figured...

Hi All, Well, I am new ot Creo & the whole PTC world. Lets chalk this one up to a major dose of frustration (clouded judgement) and the PTC interface. While I thought I had changed a few setting,...

View ArticleRe: "Model is inssufficiently constrained" error. Any ideas?
Funny, I just now went through this. I appeared it just didn't like the complexity of the geometry but that wasn't it. For some reason, I had to change the fixed constraints to a moving constraint...

I would really like to see the model, how it was constructed for the finite element method.
