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.
