Abstract
A vibration test apparatus for applying simultaneously three equal vibration forces which extend along three mutually-orthogonal axes to a test object so that each of the forces extends parallel to a corresponding respective one of three mutually-orthogonal axes of the object. The apparatus comprises a fixture adapted for attachment to a conventional shaker table or a sliptable. The fixture supports the test object in selected angular relationship relative to the shaker table or sliptable. This angular relationship is selected so that the input vibration force generated by the shaker table is translated into the three equal forces, each of which extends parallel to a corresponding respective one of the three mutually-orthogonal axes of the test object.
