Dynamic Cyclic Simple Shear System with Confining Pressure (DSS-C)

The VJ Tech Dynamic Cyclic Simple Shear System with Confining Pressure (DSS-C) is an innovative, high-precision instrument designed for advanced geotechnical testing. This apparatus features two electro-mechanical dynamic actuators, adept at applying precise vertical and horizontal loads to the sample. The sample can be either held under pressure in a modified triaxial-type cell or contained within confining rings without pressure.

These dynamic actuators are meticulously controlled by the Dual Axis Dynamic Servo Controller (DSC3000MM), which ensures seamless integration with the PC for enhanced control and data analysis via our Clisp Studio software. The apparatus is equipped with high-precision Encoders which are integrated into the servo motors, as well as external displacement sensors to accurately measure vertical and horizontal displacements. It boasts a safeguarded maximum travel range in each axis, protected by limit switches while allowing for easy adjustment of strain rate via PC.

The system is typically used with VJ Tech Hydraulic APCs, offering precise control and measurement of both Back Pressure and Cell Pressure. It also measures Vertical and Horizontal Loads and Pore Water Pressure through the DSC3000MM up to 4000 points per cycle or 500/second. The accompanying Clisp Studio csDYNSS-C software facilitates an effortless setup and execution of various test stages including Saturation, Consolidation (Isotropic, Anisotropic, or K0), Static Loading, Cyclic Shear (Stress or Strain), and Liquefaction. This comprehensive software ensures a streamlined and efficient testing process, making the VJ Tech Dynamic Cyclic Simple Shear System with Confining Pressure an essential tool for comprehensive soil analysis and research.
