C143 Rock Dynamic Triaxial Rheological Testing Machine
The dynamic triaxial test of rock and concrete is the field of rock mechanics to study the mechanical characteristics and pore characteristics in various environments. Test rock uniaxial compression, triaxial compression, a variety of tests, can automatically collect, real-time storage, display compressive strength, rebound, creep, Poisson's ratio, seepage, triaxial shear, the software automatically draws the process of stress-strain Curve and sine wave graphics, storage. The servo controller has multiple measurement channels, which can control any one of the channels, and can switch the control channel without impact during the test. The controller is easy to operate, has strong fault tolerance, accurate measurement and complete protection functions. System composition: 1. The structure of the testing machine adopts four columns.
