Seismic

We utilize two Seismic shake tables capable of qualifying a wide variety of equipment.



Our primary Seismic shake table is comprised of a 10 x 10 hexagon plate operating on an independent tri-axial system. This table is capable of testing large packages up to 20,000lbs (max total product weight including all fixtures) with ZPA of 1G. Higher ZPA's can be achieved with lower weight.

Clark's data acquisition systems feature state-of-the-art electronic monitoring systems and recorders through National Instruments (NTI – up to 26 monitoring per unit under test) to insure a detailed comprehensive test report. This meets IEEE 323, IEEE 344, IEEE 693, IBC-2009, and Bellcore specification.

The shake tables are of different sizes to accommodate requirements varying from a high input acceleration levels of small equipment (control board components) to low input acceleration levels of large equipment (such as safety injection pump).

The Clark Testing tri-axial shake table is designed to generate independent tri-axial motions (of different magnitude). The bi-axial table can generate dependent of bi-axial motions (or simulated tri-axial motions of equal magnitude in three orthogonal directions). The input in either case could be sinusoidal, multi-frequency, or sine beat to achieve required input motion or response spectrum. The tri-axial shake table could also develop uni-axial or bi-axial motions. Clark Testing also features separate single axis shake systems for both horizontal and vertical applications.
