What I suggest and worked for me is: Do different interactions of each pair of flanks in contact. In my case, since it is 34 teeth x 34 teeth, that would be 34 interactions for one rotation.

Hi A.Ismail, It is great that this thread has helped your work as well. I have not yet published my work, but I intend to do so in the next few months. If you have any doubts, let me know. Best regards,

Yes, of course, it makes a lot of sense. I guess I got so carried out trying to remake the 2d model intro 3d that I simply forgot about it. Cheers!

Hi Stefcon! In fact, I had not checked the torque: I was applying the same 500 N/mm for both the 2D and the 3D. I have just made a test, putting 5000 N/mm for the 3D model, and I have got the average stress numbers very close on both models, and better yet, the contact problem was solved! Now...

Hi guys, It is me again. I did not know if I should open a new topic, but since it is related to the same model/topic, I thought that it would be best to keep it all on the same place. First of all, I would like to thank you all for your help. I followed you advice and developed a 2d model...

Thanks! Appreciate the help very much! Now its time to go back to Abaqus and do tons of tests. Thanks to everyone that helped!

StefCon, Thanks again. I did not know one could import an .inp file, I had opened it with the notepad app. I would like to ask you about: 1) I do not really understand the purpose of the axle. My guess is that instead of using a "reference point" to constrain the inner surfaces and emulate the...

Hi StefCon, The model looks very good. I am also using a similar friction coefficient (0.12), but eventually I will have to decrease this, since the actual coefficient for lubricated gears is much lower. Would you still have the CAE and JNL files around? It would be great to see how exactly...

tkks2040, IceBreakerSours, Thank you for your help. My line of thought is the following, as I saw in this thesis, page 60: http://wrap.warwick.ac.uk/54939/1/WRAP_THESIS_JonesRG_2012.pdf Divide the problem in 3 steps 1st step: make contact by introducing a displacement (rotation) boundary...

Hi, I started the model again, this time with two equal gears. This is the new assembly: https://dl.dropboxusercontent.com/u/84784103/Meshing%20gears.rar (Same link as before but it is the new assembly inside) On the first step, I apply an angular velocity of 0.5 rad/s on gear A. On the...

Hi Mustaine, Thanks for answering. Just now I realized that I have uploaded an old version of the simulation that I was trying to do. This is how a colleague of mine made the simulation work, and I agree with you, it has very questionable definitions. I have already dropped the rigid body, and...

Hello everybody, I am new to Abaqus and have been trying to do contact analysis of a pair of spur gears some time now. If anybody has performed such analysis, please let me know. I would be really grateful! What I have done so far: 1. Created and imported a Solidworks file for the gears; 2...
