Turning Simulation Won't Turn

[jijacobs]

Hey all,
I'm currently attempting to create a simple 3D turning simulation in Abaqus Explicit. My problem is with regards to actually making the workpiece (a wheel) rotate. I'm attempting to accomplish this by defining a reference point in the center of the wheel (it looks like a doughnut so this is free in the air). I am the making a kinematic coupling constraint with the reference point and the nodes of the wheel. Finally, I applied a rotational boundary condition to said reference point that rotates it as I want with a specified ramp amplitude. The result is the workpiece registers a stress pattern that appears to be rotating like I want, but the mesh/part itself simply wiggles or does nothing at all. I've already attempted to modify the kinematic coupling to link to various surfaces on the wheel rather than the nodes and it worked even less. Any help would be greatly appreciated.
Thanks!

it wiggles because it's not constrained enough. constrain everything except axis of rotation.

I believe that it is constrained properly, although I could be wrong. I've attached the .inp and .cae files. If anybody can help me out in finding the error I'd appreciate it greatly.

Sorry, forgot the .cae file. I run version 6.12 by the way. Thanks!

Try using MPC contraints instead of the coupling (same dialog in CAE).
Are you sure your units are consistent?

I have tried MPC constraints and unfortunately they do not even register the rotational stress patter. My units are consistent with those of orthogonal cutting simulations I have done in the past, so I don't think they are the problem. Any more help is greatly appreciated!
