New on PrePoMax, it looks fantastic!
I appreciate the great tutorials from @FEAnalyst on YouTube.
Does anyone know how to get in touch with team @FEAnalyst to suggest a new tutorial on Rotary Shaft Lip Seals?
To me it would be valuable to have a comparison with results such as those presented in this paper:
Finite Element Simulation of Rotary Shaft Lip Seals
Thanks in advance!
Best regards.
Itâs usually best to ask in YouTube comments, but you can always contact me here too. Iâll send you a private message.
This is an interesting topic, but I probably wonât be able to cover it anytime soon (more about this in pm). If you prepare some geometry (the article doesnât provide the dimensions), I can help you set it up in PrePoMax. Just keep in mind that itâs often difficult to reproduce research paper results (because they use different solvers and usually provide very few details regarding the setup, particularly in this case) and that CalculiX has some significant limitations related mostly to 2D elements and nonlinearities: Known CalculiX limitations
The authors of this paper used a dynamic explicit step, which is highly limited and underdeveloped in CalculiX. You could try a static step instead or use OpenRadioss.
How you would represent the spring? According to the paper âThe spring was deďŹned as an engineering element type, which takes part in Abaqusâ. I would represent as a pressure acting in the round face.
The article leaves out many important details about the model and even has some inconsistencies. For example, it mentions an axisymmetric model, but then claims that the element type was CPS4R (plane stress). Boundary conditions and loads are not clear either. There is some reference point at the top of the seal with force applied, but no further details about it. Not to mention the lack of any dimensions. I would look for a better, more detailed paper to reproduce or even just use as a reference. The only benefit of this one is analytical calculation.
