What is it? |
|
|
|
The Electromechanical Dynamic Triaxial Testing
System (DYNTTS) is a combined triaxial cell and dynamic
actuator, the axial force and axial deformation being applied
through the base of the cell. The cell itself is screw-driven from
an integral base unit housing the motor drive. Where an optional
dynamic radial actuator is not chosen, the cell is provided with a
balanced ram to eliminate disturbance to constant cell pressure
during dynamic testing. This software-based system is controlled
from a PC running GDSLAB in MS Windows®. Data is saved and displayed
in real-time for any number of cycles. |

| What are its
uses |
| |
The GDS dynamic systems are all based around the GDS DCS high speed
digital control system with closed loop feedback of displacement and
load. With 16 bit data acquisition (A/D) and 16 bit control output
(D/A), the GDS DCS runs at a control frequency of 10kHz per channel.
This means that when running at 10Hz the system uses 1000 control
points per cycle. When running at 1Hz, it uses 10000 control points
per cycle.
The advantage of GDS DCS system is that no matter which dynamic
system is purchased, they all use the same high speed control
system. This ensures that the system has the highest level of
functionality and reliability because all of our dynamic systems,
over our complete range, use the same high specification control
system. A result of this is that the accuracy and resolution of the
test is only a function of the actuator used, whether it be a low
cost pneumatic actuator, high accuracy elecromechanical actuator or
high capacity hydraulic actuator. |
