Choosing A Vibration Test Lab Part 1 - Delserro

The DUT fixture will need to be bolted to the test lab's vibration table. Then the product will be mounted to the DUT fixture. Test labs will not drill holes in their vibration tables because they are expensive specialized fixtures usually made with magnesium. The DUT fixture is typically an aluminum plate with two sets of hole patterns. One

Optical Tables - Newport Corporation

The most critical vibration characteristic of optical table is its resonances. This is because the table is designed to be as stiff as possible and acts as a rigid body when its resonances are not excited. When the table is a rigid body there is no dynamic deflection and the beam alignment on top of the table would not be disturbed.

In order to get the most out of the vibration exciter, this fixture should carry the force from the four moun­ ting holes in the table to the mounting points on the test object with a minimum of loss and distortion. In other words the fixture should be as rigid as possible.
