ABSTRACT:
A vibration test apparatus for applying simultaneously three equal mutually-orthogonal vibration forces to each of at least two test objects so that each of said forces extends parallel to a corresponding respective one of mutually-orthogonal X, Y and Z axes of each test object. The apparatus comprises a fixture adapted for attachment to a conventional shaker table or a sliptable that has two or four object-supporting plates disposed in a selected angular relationship with 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 each test object secured to said fixture.
