Quasi-Static Actuators

Quasi-Static Actuators



Servo-Hydraulic Loading Systems

The system is developed by the pioneers of servo-hydraulic loading systems in Turkey, TDG, and is being used for general purpose structure and earthquake tests.
The system can be customized for different force and speed capacities, and installed as a turnkey solution including hydraulic actuator, hydraulic power pack, electronic control system and software.It is possible to use 2 or more actuators in seperate or synchronized modes.

• 20 / 50 / 100 tonf or higher
• Full Control Over Software - Easy and Flexible
• Position Control&Force Control – Instant Transition
• Load Cell and Position Transducer Integrated to the Actuator
• Position Sensitivity up to 0.5 Microns
• Continuous Technical Support

Multi Axes System Designs:
• Synchronization Between Axes
• Force/Displacement
• Special Test Scenarios

QUASI-STATIC Tests are Moved to the Field!

Civil Engineering Tests are moved to the field. Strucutral Mechanics are now not limited to small scale laboratory test but can be applied on real structures.
