Thank you for your answer. Yes I figured I had to do the CSYS creation in post-processing step. Since I am doing batch simulations I therefore need to incorporate the CSYS creation into the python script.
I now struggle to understand why the node selection which is shown above won't set the...
I'm trying to define a cartesian coordinate system following three nodes.
First, I tried to create it in the model file, but strangely, the CSYS does not appear in the output database unless i create a dummy load which refers to this CSYS (e.g. 0.00001 N). Also, the CSYS does not appear to...
Ah yes, good point. I will make a deep dive into the solver details about contact node tracking and large sliding.
Also, thinking about making some parameter studies to visualize the effects of friction, element size, sliding distance etc.
Hi DanStro, thank you for your reply! Much appreciated.
What change exactly are you thinking of? In the contact algorithm itself or in the nodal displacements?
Thank you for your reply! Yes I expected quite different results since the contact area and friction force will not be the same for the two load cases.
I'd think the stresses are physical, but i'm struggling to interpret the slip patterns (see attached figure here). This pattern seems...
Hello,
I'm working on simulating hertzian (line) contact with very small (micrometer scale) sliding motion typically found in fretting applications. In such applications, a central stick zone is seen, whereas at a certain distance towards the contact edges, sliding will occur, giving rise to...
Hello,
I've just been through NX training at work and started on this relatively complex drawing showing a shaft arrangement for an engine. However, the area of interest is only a small fraction of the total arrangement, and drafting mode seemes to be slowed down by the fact that NX tries to...
I have a reference point in each gear center which is connected to the gears with kinematic coupling. A moment is acting on one of the reference points and a displacement is applied to the other one, making the gears acting against eachother. I thought that dividing the reaction moment by the...
Hello DrBwts,
thank you for your interest.
As far as I understand, neglecting dynamic effects and looking quasi staticly at it should give reasonable results. The overall stiffness in the gear pair changes as different number of teeth come into contact and due to the points of contact moving...
Hello skilled engineers,
I'm trying to generate a plot of mesh stiffness in a spur gear pair as they rotate.
I've tried to do this using a static analysis by applying a moment T on the pinion while the gear rotates. Im measuring the rotation in both the pinion and gear, and the transmission...
