GDS - Model DYNTTS -Advanced Dynamic Triaxial Testing System
The Advanced Dynamic Triaxial Testing System is a high-end, no compromise testing apparatus combining a triaxial cell with a dynamic actuator capable of applying load, deformation and stresses up to 5Hz. The cell itself is screw-driven from an integral base unit housing the motor drive. Axial force and axial deformation are applied through the base of the cell. The system can be combined with a dynamic cell pressure actuator such that cell pressures may also be applied dynamically up to fundamental frequency of 5Hz.

- Key features : Benefits to the user
- High accuracy electro-mechanical control: : The DYNTTS system is capable of very small strain static tests through to large strain dynamic tests.
- Interchangeable load cells: : Allows user to accommodate very soft to very stiff soils with ranges of 1, 2, 4, 8, 10, 16, 25, 40 and 60kN.
- In-built balanced ram (up to 5Hz systems): : Keeps cell pressure constant during cycling, meaning a dynamic pressure controller is not required (unless dynamic cycling of cell pressure is required).
- Interchangeable pedestals and triaxial extension top caps: : Allows testing of 38, 50, 70 and 100mm diameter test specimens in the same cell.
- Direct closed loop of axial displacement & axial force: : Accurate control in either axial displacement or axial force mode.
- Actuators : High accuracy electromechanical
- Axial Force Accuracy : <0.1%
- Axial Force Accuracy : 24bit (i.e. <0.4N for 10kN load cell, <1.5N for 40kN load cell)
- Axial Load : 10, 40 or 60 kN
- Computer Interface : USB
