Re: FEM on rubber disk
I am not sure if it comply with the design of your assembly, but I would have added a pressure load on the entire bottom surface of the disc and also constrained displacement of the top of the outer...

View ArticleNon linear or linear setup in fastener simulation in creo?
As assigning fastener connections to the assembly, creo simulate creates contact surfaces in between two surfaces. My question is whether I should check the "Nonlinear/ Use load histories" box or not?...

David, The driver 'controls' the rotation, (the DOF you have in your mind). Because it is driven, it is not a DOF. Regards Charles
View ArticleRe: About Redundancies and DOF
thanks Charles if i rotate the gear with a torque then DOF will be 1 but if i rotate the gear as mentioned with a motor the DOF will be 0.Could you explain it a little further?
View ArticleRe: About Redundancies and DOF
Servo motors directly control the DOF of the joint axis you apply it to, so that DOF is taken away and rendered "fixed", or "prescribed". Any single force or torque does not control the absolute motion...
View ArticleRe: About Redundancies and DOF
yup. Distinguish between force and servo motors. A force motor : a torque will rotate the gear about it's axis DOF, the rotation can be influenced by other forces/inertia of the gear. A servo motor :...

How about creating a surface on a plane using the edges then measure the area of the surface.

Thanks for your comment, I have basically been doing just as you suggested. When I have simple geometry I have no problem with that as I open the valve plate. The big problem I have is when the profile...

View ArticleHow to delete unwanted simulation analysis files?
I have a lot of analysis files on my computer which I need to delete. Is there a way of deleteing them through Creo, or do I have to go through my documents?Thanks
View ArticleRe: Bonded contact analysis
In my opinion, when you have to do a contact analysis, one way to have a good control on the interfaces is setting the analysis generally free, and set all interfaces between parts after.This...
