Hello Hugo. Your point of view is very interest, even, I think same as you. However finally I have solved my problem changing boundary conditions. In one support I have restrained in translation along x,y,z, but allowed to pivot around x,y,z and of other side restrained in translation along...
Hi guys!
I have made a FEM analysis of a roller and the results show below.
The forces acting are flexion and torsion. The diameter max. of the roller is 330 mm and 5000 mm of total length.
I do not like high stress values in the fillet zone. I tried refine mesh but the values increase...
Finally I resorted to the standard. There I was able see what are the finished product tolerances (bent plate). Then I adjusted my design for meet such specifications.
Thank you very much to all for your feedback.
Sorry for my english!
Greetings!

"If the rolls themselves are very large in diameter, they will be stiff in bending, but there will be a lower limit on the diameter of the workpiece you can roll.
You have to find a compromise somewhere in that multidimensional space"
Excellent point! I´m work about this.

I plotted deflection Vs. roller diameter. My problem is find in this range which is the optimum value of design. Is true, I do not believe that exist nothing of this in the codes, though I did think that there would be something to the structural case (see image).
I have been trying to get in...
Hi friends:
I am working in the design of a 3-Roll Plate Bending Machine of pyramidal disposition. I am writing to enquire about the deflection rolls. I would like to know what is the maximum value or limit permissible deflection for the rollers.
I suppose that exist standards or...
Dear Ian, please do not worry. You have been very helpful.
I not have the input/output files for the APDL analysis, because the analysis sucssefull that is seen in this video, belongs to a user of youtube.
I've tried all the contacts and none worked. Finally I decided to remove the bottom...
Friends, thanks for the help, but for now, I have not been able to solve it. I will continue trying. When you have an answer I will make you know. I leave the geometry of the problem in case anyone wants to try. Thank you very much...
Hello Ian! Thank you for your comments and suggestions!
I don´t think that the problem is the mesh, I am inclined to think this is because the boundary conditions or contacts. In any case proves refining the mesh.
I have restricted movement in the direction perpendicular (Z) to the plate in two...
Hello everyone. I'm trying to simulate the bending of a plate in ANSYS WB.
I had to play some advanced options that not finish understand. I have some screenshots to see where I was.
I've drawn a small geometry in MD, just a test.
I want to know the support reactions plastic...
