Seismic Simulators (Shake Tables)
The MTS seismic simulator portfolio features a host of standard, pre-engineered and custom tables for evaluating everything from nonstructural infrastructure to structural components and substructures to model-scale and full-scale civil structures. Precise seismic loading in up to six degrees-of-freedom can be applied to a broad array of test articles to evaluate their behavior under real-world earthquake conditions.

- All specifications can be customized
MTS is well known for its seismic expertise and eagerness to work with customer's specific needs. Many of the largest seismic tables in the world utilize MTS actuators and seismic control technology. Full scale structures can be tested in a controlled laboratory setting using massive or multiple seismic tables being controlled together.

- All linear translation, velocity and acceleration values are based on single degree of freedom table movement about, or from the table-top center.
- All velocity and acceleration values are peak levels. Indicated levels of performance are not achievable throughout the simulation frequency range.
- Maximum performance is only achievable when payload is mounted wholly within 1m radius (in X-Y plane) of the table center. Stated performance cannot be realized with all specimens as it is dependent on specimen modes and attachment to the table.
- Assumes solid steel test payload rigidly mounted above the table-top center
