DYNAMIC TRIAXIAL TESTING SYSTEM (DYNTTS-10)
Product Code : DYNTTS-10
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 10Hz. 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 the machine (i.e. 2Hz, 5Hz or 10Hz).
| 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. |
