Patent ID: 8893552

Claim:
An improved, light weight, rigid, multi-axis vibration table for maximizing high frequency and high energy vibration transmissions to test products mounted on the table while minimizing variations in the magnitude of the vibrations in each axis at different lateral points on the surface of the table, comprising: a rigid table top comprising a pair of vertically spaced upper and lower rigid metal plates that are circular in shape, the plates being separated by rigid spacers and rigidly fastened together by threaded fasteners, the upper plate having one or more spaced internally threaded openings therein for mounting one or more test products on the upper plate; a plurality of vibrators mounted at skewed angles on an underside of the table top, the vibrators generating simultaneous vibrations in the table top and the test products mounted thereon in x-, y- and z-axes relative to the plane of the upper surface, whereby the circular table top causes reduced variation in the magnitude of the vibrations in each of the respective x-, y- and z-axes at different lateral points on the upper surface of the table in comparison with a table top having a rectangular profile.
