Patent attributes
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.
