TESTBOX SHAKETABLE
SERVO ELECTRO-MECHANICAL SHAKE TABLE
(EARTHQUAKE SIMULATOR)
This product can simulate the previously recorded earthquakes, and can also apply
defined waveforms such as sinus, triangle, etc. or user defined customized
acceleration
or position profiles , as well.
This simulator has a servo-motor and a PID controller which can easily be controlled
by a computer software. It is mainly used for training purposes at Civil/Structural
Engineering undergraduate/graduate education.
This product can also be used for performing small scale structural mechanics,
earthquake, soil and geological engineering tests, or for calibration of
accelerometers
and vibration sensors.
In the contest which is being organized by DASK(Turkish Catastrophe Insurance Pool),
annually in TURKEY, multiple TESTBOX-SHAKETABLEs are used as the simulators,
combined with complementary measurement systems and software.
This product is being used widely all over the world such as United States, India,
Thailand, Spain, Indonesia in addition to the universities and research institutes
in
Turkey.
COMPLEMENTARY MEASUREMENT SYSTEM
The earthquake simulator is generally used together with a complementary
measurement set in order to measure reactions over the model and make acceleration
and displacement calculations.

CAPACITY/ TABLE SIZE/ STROKE
This practical product can be manufactured at different table dimensions,
displacement and payload capacities
optionally.
Dynamic actuator capacity options are 1/2.5/5/10 kN. Flexible sizing and dynamic
capacities make these simulators
suitable for industrial product and material user-defined vibration tests and small-
to medium scale model tests in
earthquake and soil engineering. Higher capacities are possible with customized
design opportunities.
