Model 831.50 x 1000 Hz Elastomer Test System
Features high frequency test capability

Benefits» Speed, accuracy, and reliability» Stand-alone system does not
require a reaction mass
» Accuracy and repeatability to1000 Hz» Tests both materials andcomponents» Complete suite of software
applications lets you perform awide range of tests

The MTS Model 831.50 high frequency
elas­­tomer test system was engineered tomeet the high frequency, high precision
testing requirements of the automotiveand materials industries. Its standard
configuration features a frequency rangeof 0.01 to 1000 Hz, with +/-10 kN force
and displacements of +/-20 mm.
The 831.50 was developed for tests
of material properties as well ascomponents such as engine mounts,
bushings, transmis­sion mounts, andother vibration damping and control
elements. It is designed for mea­suring
dynamic properties such as K*, phase,
E*, tan delta, energy, and damping
coefficients over its wide frequency range.
Its unique load unit was engineered withhollow columns and a stiff, but light,
cross­­­head that both minimizes column
lengths and avoids introduced resonances.
The load cell is recessed in the base tominimize the height of the exposed columns.
Other load frame features include a large
seismic base isolated from floor vibrations
and a spe­cial hydraulic system capable ofsustained operation at frequencies up to1000 Hz.
In addition to its standard elastomer
appli­cation software, the Model 831.50
can employ MTS RPC® simulation software.
Adding it increases the capability of thesystem to perform fatigue and durability
testing, coupled with dynamic property
measurements. By being able to sequence
between fatigue/durability and measurement/characterization processes, you can monitor
dynamic changes in the component ormaterial due to the cumulative effects ofload fatigue cycles.
An optional temperature chamber package
allows you to observe the effects oftemperature on fatigue, characterization,and degradation.

FlexTest® GT
The FlexTest GT is a proven control
solution for performing complex
materials and component testing.
The FlexTest GT runs with MTS 793
software and a multitasking Windows™
operating system, allowing you to takeadvan­tage of the full array of proven
MTS test application software.
