Dynamic v Couple Unbalance
Dynamic v Couple Unbalance
(OP)
If I know static imbalance in two different planes, I can calculate couple imbalance. Dynamic imbalance is the "combination" of couple and static imbalance. If I know static imbalance and couple imbalance, how do I calculate dynamic imbalance?

That is, you need three pieces of information
- the change in response (in phase and magnitude) at measuring plane 1 to a trial mass on plane A call it R1A
and
R2B
and
R2A or R1B, but preferably both

Add 'em up vectorically or graphically.
The couple is 2 equal and opposite imbalances separated by some distance. Choose that distance as your distance between correction planes.
Then break the "static" unbalance into 2 equal pieces, and add one to each end.
