Vibrafuge - A Combined Environment Testing Facility Vibration Testing on a Centrifuge 892368
Vibration testing in a centrifuge acceleration field (up to 50 gs) can be accomplished in either of two axes relative to the centrifuge acceleration with a modified, commercially available, electrodynamic shaker and the use of a specially designed orthogonal motion converter.
Fixing the shaker armature axis in-line with the centrifuge arm (head towards the pivot) keeps the inertial forces on the head in the one direction which can be offset with servo controlled pneumatic bags located beneath the shaker head.
Testing in an axis perpendicular to the principal axis is accomplished with the orthogonal motion converter which is driven by the shaker head.
