Vibration Fixture Orientation
Vibration Fixture Orientation
(OP)
If I am designing a vibration fixture for testing in the vertical axis, does it matter if the test item is mounted upside down?
Some opinions say yes, since gravity is adding a 1g downward acceleration.
My opinion is that the feedback loop in the vibration controller will neutralise this and give an even acceleration in the up and downward directions.

Sure, if it's a solid block of tungsten. Since you've provided zero information about the UUT, no one can give anything but a generalized answer. If there's anything that can decouple under test, then it might make a difference which way it's oriented, since you have no ability to invertgravity.
