I'm Studying on drill string vibration, I need some information & resource about coupled vibration (lateral, torsion, axial). Is there any one who studies on analytical and numerical solution in this matter?

Try a Drill string design company like Fearnley Proctor may be able to suggest something.
Or the MWD companies- they monitor vibration all the time for stick slip, bit bounce and so on, could offer you raw data perhaps.
