Cabe, really I was just considering mass ratios. That is a handy cheap trick for guessing at what will happen in some situations.

Your outcome was outstanding considering you were new to the field of rotordynamics. Good job, it's always a good idea to never settle for the status-quo.

rotordynamics and system understanding

Quite an interesting post, and on a topic that I have not studied much. It certainly required a bit of insight to understand what the changes had to be, and it is interesting that the techs assumed that the part needd to be redesigned. That is the sort of attitude that comes with not understanding just what is happening with a process. Of course, if they understood as much as the engineer then they would be designing the parts instead of testing them. 

It sounds like the rotor being tested must have been fairly small for setscrews to be equal to any signifigant portion of the mass of the part.

Don't change your design

It is interesting that the technicians seemed to imply that, since your design was the most difficult to test, that you should change your design.  It is good that you changed the test fixture instead.
