Request: Gear contact simulation tutorial

General Questions
2

Not yet (only for standalone CalculiX) but I plan to record such a tutorial. Here’s my YouTube channel with PrePoMax tutorials:

I always include verification with analytical calculations and that’s what usually delays my tutorials but it shouldn’t be so problematic with gears.

For now, I can give you some advice regarding such a simulation:

  • try to do it in 2D (plane stress) if possible - meshing will be much easier
  • apply local mesh refinement to the contacting teeth
  • define a contact pair for all surfaces of the teeth that may come into contact
  • apply rigid body constraint to the hub of each gear
  • fix one gear (via this rigid body constraint)
  • apply rotation or torque to the other gear (again via the rigid body constraint)

Then you can try to increase the complexity of this simulation but the settings suggested above should be a good start.
