Dual Axis Dynamic Triaxial (Hydraulic) System with DPC

Dynamic Triaxial (Hydraulic) System (20Hz 50kN) with Dynamic Pressure Controller

For prices: call +44 (0)118 945 3737 or Email us
The VJ Tech Dual Axis Dynamic Triaxial (Hydraulic) System with DPC is capable of providing fully automatic high frequency and load dynamic (cyclic) Triaxial testing using a 250 kN frame with hydraulic actuator and accumulators, together with a Hydraulic Power Pack for applying and dynamically adjusting the vertical load or displacement, in conjunction with a Dynamic Pressure Controller for controlling dynamic cell pressure

There are two Dynamic Servo Controllers for actuator control and sensor feedback, rack mounted in a cabinet. The hydraulic DSC3000H is used for hydraulic actuator cyclic control and also measurement of Load, Displacement and PWP and the electro-mechanical DSC3000M is used for dynamic Cell Pressure control and feedback. A hydraulic APC is used for Back Pressure control.

The user friendly Clisp Studio csDYN software provides the necessary test configuration, control and data acquisition and conforms to ASTM3999 & ASTM5311.
