Mechanical Testing |
 |
|
|
Equipment is mounted atop the SwRI seismic facility and exposed to a simulated earthquake environment. |
Mechanical testing of telecommunications equipment for NEBS compliance is conducted at Southwest Research Institute (SwRI). In addition to mechanical testing, simulations and evaluations are available, including:
Operating, transportation, and storage environments
Low-level vibration that can be found in the installation location while the test item is operating (e.g., office vibration)
Vibration encountered during transport (transportation vibration) or storage
Large displacement vibration encountered during earthquakes
Shock encountered during installation, transport, or storage of the test item
Key NEBS Mechanical Testing Features at SwRI
 |
|
Equipment packaging is evaluated for effectiveness in transport by exposing it to simulated vibration and shock on electrodynamic shakers. |
Multiple electrodynamic shakers available for NEBS transportation vibration or ETSI random, sine or "bump" testing.
Earthquake simulation facility has been audited by Telcordia to meet NEBS requirements.
10" displacement-capable earthquake simulation facility that is biaxial capable. Allows the client to test in two axes before having to rotate the concrete slab 90°.
Digital video is taken during the earthquake simulation for inclusion in the electronic test report as an embedded MPEG file.

Mechanical Testing Capabilities
Earthquake Simulation Capabilities
Using a 10-inch stroke, biaxial, hydraulic actuated earthquake simulator with computer control, SwRI runs synthesized waveforms like the Bellcore GR-063-CORE VERTEQII acceleration time history or synthesized random drive signals to meet required Shock Response Spectra (methods described in IEEE 344 and IEC 68-3-3).
Vibration Test Capabilities
Sinusoidal, Random, Shock, or combinations of these are possible.
Drop Test Capabilities
Frames or shelf level components can be dropped in accordance with the NEBS or ETSI defined configurations. A 5-ton overhead equipped with a pneumatic release is used for frames.
