Hello,
I'm facing this problem with Abaqus: a crankshaft rotates with a constant speed. A varying force is applied on the surface of the piston rod. The inertial forces must be considered-> Dynamic Explicit. I predefine a rotating velocity for the whole model (Predefined Field). The problem is that I don't know how to apply the BCs of the ball bearings. I have applied fix BCs (displacements) at the Initial Speed and then, for the Dynamic Explicit, I have applied a rotating velocity for those BCs. I think this is incorrect at all.
How would you do that? Any suggestion. Many thanks in advance.
