ABSTRACT:
A vibration test, bearing table apparatus comprising a support block having a surface slideably supporting a test piece-carrying slip plate intended to oscillate along a single predetermined axis at a desired test frequency responsive to shaker head driving of the slip plate is provided, with an improvement comprising means within the locus of sliding engagement including a cooperating shaft and bearing assembly distributively coupling the slip plate and support block together in a manner maintaining the test piece on a single degree of freedom path coincident with the test axis, whereby tendencies of the driving force to impart spurious cross-axis pitch, yaw and roll test piece motion relative to the intended test axis are blocked.
