Shaft Vibration / Deflection

I have a problem I am trying to analyze using Simulation.  I need to analyze a rotating shaft to determine harmonic vibrations and deflections at certain RPMs. I have set up the simulation to use bearing fixtures at two split portions at the end of the shaft.  The details are (I'm also attaching the solidworks file of the shaft):

 

RPM: 3200

Shaft dia: 3.001"

Shaft face length: 92.125"

Bearing face length: 2.125"

Material: Hot Rolled Steel 1018

 

I've tried using the Frequency analysis solver but get extreme deformations that I know aren't accurate through observation.

 

Anyone have any suggestions?
