Abstract
A vibration test fixture system for use with a conventional shaker table. The fixture system includes a cube fixture for supporting an object to be tested and a head expander for supporting the cube fixture and for providing a mechanical and vibration transmissive connection between the cube fixture and the shaker table. The fixture system also includes an index mechanism for automatically repositioning the cube fixture relative to the head expander so that the object may be vibration tested along mutually orthogonal axes of the object.
