Flexible chain with NX8.5

Flexible chain with NX8.5

RE: Flexible chain with NX8.5

No, deformable component is not design for this purpose.
The best exemple of use of this feature is a spring.

Your components are rigid, it's only a matter of assembly constraints.
Look for the "motion" application, you should be able to achieve what you want.

OK, but I don't have motion license and PRO/E seems to be able to do this with basic license

Using the standard assembly license.
When everything is well constrain, then, your chain link will move.
But, I don't know how to force them to be aligned on the ground or how to give them a "real" behavior.

RE: Flexible chain with NX8.5

I get it to update quite nicely, it doesn't behave like a true cable chain since the real thing cannot bend in the "wrong direction" but apart from that it updates.

Anyhow
I removed the constraints in the "sub ass" between the start-end of the chain. ( 2 constraints, parallel and distance deleted.)
In the "assy" i selected the upper end of the chain , RMB - Override position.
Then constrained the upper end to the plate.

After moving the "plaque", i need to select one of the links in the middle of the chain RMB - Move : drag it into a better position.

I have a video showing the complete operation, but it's 7.6 Mb, so i'm not sure if i should upload.
leave a reply if you want the video.

Tomas

Thanks Tomas

I have forgotten to use override constraint

Try to send the vidéo if possible

Toost,

I think the file size limit for engineering.com (the attachment link below) is 20 MB. Your file should upload fine.

RE: Flexible chain with NX8.5

Here’s the video of the cable chain.
It’s captured using Jing by Techsmith.com ( freeware) it is in Shockwave Flash format. ( .swf)
Save the file to disc, it's compressed in 7zip. extract and open it with Internet Explorer. ( Do not use a “video player”, it will not work.)

Tomas

RE: Flexible chain with NX8.5

Good.
Beside that, do you like the "assembly constraints" ergonomy ?
Do you find easy to locate / repair / modify a constraint ?

Hi Stéphane,

I like assembly constraints ergonomy. Even I remember the easy way to find them with mating conditions in NX4, the following process is a good solution to explore the assembly:



And the result



Or you can also use the new constraint navigator



Don't hesitate to contact me directly in france wink
