Dynamic Cyclic Simple and Direct Shear Apparatus (DSS)

The VJ Tech Dynamic Simple & Direct Shear System is an advanced, versatile testing solution expertly designed to conduct a variety of shear tests, including Dynamic Simple Shear, Direct/Residual Shear, and Direct Simple Shear.

This system features two precision electro-mechanical actuators that facilitate both horizontal and vertical movements. These actuators are seamlessly controlled by the state-of-the-art Dual Axis Dynamic Servo Controller (DSC3000MM), which connects to a PC via Ethernet or USB, ensuring user-friendly operation and robust data management via our Clisp Studio Software Module.

The Dynamic Simple & Direct Shear System is enhanced by its interchangeable assembly options, allowing the user to switch between Direct Shear and Simple Shear setups based on their specific testing requirements. It is especially suitable for conducting cyclic controlled tests, thanks to its ability to generate a variety of waveforms such as Sine, Square, Triangular, Haversine, Rectangular, and Saw Tooth, in addition to accommodating User Defined waveforms.
