Hi Martin, Great. Thanks for your answer!

Hi, I´m using the Abaqus/Explicit and I have some questions about the time period. I know that the time period is the time of the event being simulated but How should I define the time scaling factor?. The time scaling factor is the "n" defined in the Analysis user´s Manual? I´ve been...

Hi, Yes you are right!, it´s 90 degrees not 45. I read the manual but I´m having dificulties to define the master and slave surface. As my model is just a quarter of the cylinder in the first quadrant, which surface should be the master and which one the slave?. I´ve attached the model...

Hi Johnhors, Thanks for your help. I´ve started to read the Manual about the Cyclic Symmetry but it´s no quite clear. I´ve modelled a quarter of the cylinder (45 degrees, first quadrant) and according to the manual I should have to define the master and slave surface or nodeset. My question...

Hi Rob, Thanks a lot for your answer. So there is no way to simulate a half cylinder (3D) with a torsion moment. I will validate the resutls with the axysimmetric. Best regards. Zeke

Hi, I guess that it´s a very simple problem but I can´t find the solution. I simulated a hollow cylinder, the applied load is a torsion moment in the Z-Axys (3D model). To apply it I create a RP and I coupled this RP to the front surface (Kinematical Coupleing). The BC are applied at the rear...

Hi, I´m sorry for not answer before. I´ve coupled the reference point to a surface. One RP for the Driver and one RP for the Driven. Both RPs are in the axis of rotation. For the Driver, I applied the moment (UR3) and the BC(only free UR3) on the RP. For the Driven I applied the BC (fully...

This is what I´v done, (I´m analyzing a cylinder to see if it works) I create the RP and the Kinematic coupling constraint. After pick this RP as a control point I chose the "node region" and I applied a torsional moment in the direccion of the axis of rotation (UR3). As you said, On the same...

Hi, Thanks I want to fix the center of a cylinder and then apply a torsion moment (the only DOF free should be the axis of rotation) to see the rotation. For doing this, I create a reference point on the axis of rotation and a cylindrical coordinate system. Then I create a Kinematical...

But that is not the answer for my problem. Do you know how to fix the center of a gear?

Hi, I´m trying to simulate the contact between two gears. Each gear has 60 triangular teeth and all of them are in contact at the same time. I have one external gear and one internal gear. The internal gear is driven by a torque applied at it center. I know that I should fix the center of the...
