| Rock Dynamic-Static True Triaxial | Grey |
Rock triaxial testing machine is the most advanced testing system with two rigid and one flexible loading in China, which can meet kinds of rock specimenss.
The fully closed-loop control of test force (stress), deformation (axial strain, radial strain) and displacement (compression rate) during rock testing process that adopts advanced fully digital coordinated loading measurement control technology and electro-hydraulic servo system.
| Model | DSZD-500 |
| Servo Loading System | Three independent servo loads mutually perpendicular to each other. And six electro-hydraulic servo loading cylinders are respectively controlled. |
| Mainframe structure | Overall frame structure,vertical stiffness≥9MN/mm, horizontal stiffness≥9MN/mm |
| Vertical testing force | Max force:5000kN, range:50kN-5000kN（1-100%FS）,resolution :30N（±1/180000ã€same rate）,Deviation less than 0.1%, Vertical loading rate 10N-20KN/s |
| Front-back and left-right( X /Y)testing force | Max force:3000kN, range:30kN-3000kN（1-100%FS）,resolution :20N（±1/180000ã€same rate）,force deviation and fluctuation controlling less than 0.1%, Vertical loading rate 10N-20KN/s |
| Displacement | Displacement range 0-200mm, accuracy<±0.5%FS,resolution 0.001mm, fluctuation controlling <0.1% |
| Deformation | Deformation range0-10mm,deformation resolution 0.0001mm,deformation accuracy <±0.5%FS |
| Specimens spec | Configurate below head clamps:200×200×200mm；100×100×200mm；50×50×100mm |
| Servo oil source | 31.5MPaï¼›100L/minï¼›power consumption 55kW |
| Multi-control and unshock conversion | To achieve constant of testing force/displacement/deformation/rate/ rate displacement/rate deformation and ways of control, while reach to force/deformation/displacement all three step control, and converting with each other. The PC would protect and control the overall process. |
| Shock and disturbance loads of vertical-horizontal derection | Shock and disturbance loads(Random wave, sine wave, triangle wave, square wave, oblique wave): shock force during 0-500kN,rate during 0-50Hz, disturbance force during0-500kN, force measurement accuracy ±0.5%FS. Disturbance requirement: it can change the waveformã€point of actionã€rateã€peak valueã€amplitudeã€duration and se position, while disturbance loads loading at any time |
| Disturbance Loads Action | Point way is directly action on the specified point to the specimens |
| Surface way is directly action the specified surface to the specimens which can be more than one form combination. |
