dynamic analysis of a crankshaft

dynamic analysis of a crankshaft

(OP)
Hello,

I only have two or three month of experience with the Abaqus. I'm facing now a problem related with a crankshaft (with just one counterweight). It is expected that I have to analize the crankshaft dinamically.
My doubt is, once I have defined the contact elements in the joint with the piston rod, and I have applied the changing load over this joint in the Step 1 "Implicit Dynamic", do I have to define a rotational velocity for the crankshaft, in order to take into account the inertial forces of the crankshaft (they are very important, due to the counterweight), or are already this inertial forces taken into account in the Step 1 "Implicit, Dynamic". Should be the first case, how can I define the rotational velocity for the crankshaft? I have tested with the BC-velocity angular, and then the constraint-tie, and a reference point, but I only get to rotate the half of the shaft.

Many thanks in advance
