US Patent:

7886606, Feb 15, 2011

Filed:

Apr 10, 2006

Appl. No.:

12/096972

Inventors:

John K Hanse - Allegan MI, US

International Classification:

B06B 3/00

US Classification:

73663

Abstract:

A vibration table for testing products employs threaded inserts for mounting the test products or fixtures therefor on the table. The threaded inserts have enlarged and elongated threaded shafts that engage threaded openings in the upper surface of the table, with enlarged heads on the inserts being positioned adjacent the outer surface of the table or the outer surface of an insulation layer mounted on the table. The inserts have elongated internally threaded openings therein, to which the test products or fixtures are bolted by elongated bolts. The inserts enhance the transmission of vibration forces to the test product with or without an insulating layer. They also provide improved temperature uniformity by providing air circulation between the test product and the table.

John K. Hanse - Allegan MI, US

Assignee:

HANSE ENVIRONMENTAL - Allegan MI

International Classification:

B06B 3/00

US Classification:

73663

Abstract:

A vibration table having an upper surface defining a plane and on which test products are mounted by bolts that engage spaced internally threaded openings in the upper surface. The vibration table has mounted vibrators for generating vibrations in x-, y- and z-axes lying in the plane of the upper surface. Variation in the magnitude of the vibrations generated in the x-, y- and z-axes over the surface of the table are minimized by providing an upper surface that is circular in the plane of the upper surface.

International Classification:

G01M 706

US Classification:

Abstract:

A shaker table comprises upper and lower plates spaced apart by a plurality of spacers that fit between the plates. Each spacer has an upper shaft, which threads into a vibrator opening in the upper plate, and a lower coaxial shaft, which slides into a vibrator opening in the lower plate. The spacer has a threaded internal coaxial opening extending through the spacer. A bolt for securing a vibrator to the bottom of the table engages the internal opening and secures the vibrator and the lower plate to the spacer and upper plate. A mounting bolt for attaching a test product or test fixture to the top of the table threads into the internal opening from the top.
