Crystal Instruments North Carolina Vibration Testing Lab

The CI North Carolina Vibration Testing Lab in Kannapolis, NC (1548A Roger Dale Carter Boulevard) is one of Crystal Instruments' testing facilities. Its equipment includes single-axis shakers, multi-axis shakers and temperature/humidity/vibration chambers, so systems can be matched to products of different sizes and payloads.

The lab's large water-cooled electro-dynamic systems feature a 2500 x 2500 mm high-pressure monobase slip table with optional automatic armature centering and a motorized gearbox for shaker rotation, plus a 2500 mm square magnesium head expander. The water-cooled E-Series shaker delivers 196 kN sine peak force and 392 kN 6 ms shock force over 5-2200 Hz with a 2000 kg max static payload, and is designed for large payloads up to about 6000 kg (13,200 lb), suited to large electronic parts, connectors and mechanical assemblies.

Air-cooled systems cover smaller products. A small air-cooled system provides 5.88 kN sine peak force and a 200 kg max static payload, suited to small electronic parts, connectors and hand-held units; the medium-to-large air-cooled M5044A provides 49 kN sine and random rms force and a 1000 kg max static payload for medium electronic parts and flight and ground vehicle components.

For multi-axis work the lab offers MIMO and MESA systems. The air-cooled MIMO system performs simultaneous three-axis vibration testing that simulates real-world environments and satisfies MIL-STD-810G requirements, cutting test time by two-thirds, using Crystal Instruments' Spider vibration controller. The MESA (Multiple-Exciter Single-Axis) air-cooled system performs multiple-exciter single-axis vibration testing for medium-sized electronic parts and flight and ground vehicle components.

The Temperature, Humidity and Vibration (THV) system offers testing from -70 °C to 150 °C using Sentek Dynamics chambers. An AGREE chamber (5 °C/min) is combined with a 32 kN shaker and an 800 x 800 mm low-pressure slip table, applying temperature, humidity and vibration in one chamber with a single comprehensive report.
