Vibration Testing

Vibration testing is accomplished by introducing a forcing function into a structure, usually with some type of shaker. Alternately, a DUT (device under test) is attached to the "table" of a shaker. For relatively low frequency forcing, servo-hydraulic (electro-hydraulic) shakers are used. For higher frequencies, electro-dynamic shakers are used. Generally, one or more "input" or "control" points located on the DUT-side of a fixture are kept at a specified acceleration. Most vibration testing is conducted in a single DUT axis at a time, even though most real-world vibration occurs in various axes simultaneously. MIL-STD-810G, released in late 2008, Test Method 527, calls for multiple exciter testing.

ECON provides the brain of the vibration test system--vibration controller, for electro-dynamic and servo-hydraulic shakers. We provide solutions for not only single-axis vibration testing, but also multi-axis vibration testing.
