Abstract

A vibration test fixture assembly for releasably securing a test object to the top surface of a sliptable and for rotatably supporting the test object so that the test object can be repositioned between vibration tests without detaching the test object from the fixture. The assembly comprises a bottom plate, a top plate positioned on top of the bottom plate, and a plurality of spring-loaded bearing assemblies between the top and bottom plates for permitting the top plate to rotate relative to the bottom plate except when a downward force of sufficient magnitude to overcome the spring bias of the bearing assemblies is applied to the top plate. The assembly also comprises a plurality of clamps positioned adjacent the top plate for applying a downward force to the top plate sufficient to overcome the spring bias of the bearing assemblies and cause the top plate to engage the bottom plate. The test object is secured to the top plate and the bottom plate is secured to the top surface of a sliptable.
