Automatic computer controlled rock shear strength testing machine
Performance characteristics
1. Electro hydraulic servo oil source, dual control pressurization. Liquid crystal display electro-hydraulic control normal force application; Computer controlled collection of shear force; Set up vertical force measurement for deformation; Set constant shear stress to measure deformation.
2. Special software for data collection, real-time monitoring and storage of shear force values, displacement, and normal deformation. shearing stress
Load deformation relationship curve, vertical deformation horizontal deformation relationship curve.
3. During the experiment, the data acquisition control system controls the shear rate and can set a constant shear rate arbitrarily. It collects normal deformation, shear force values, and strain; Constant shear strain can be set arbitrarily, and shear force values can be collected.
4.The experimental data can be freely exported for users to view and analyze.
