Rock Triaxial Testing Machine

The mechanical properties of rocks depend on the interactions between constituent crystals and particles, as well as the presence of factors such as. Under non-equal triaxial compression conditions, as the minimum principal stress increases, the failure strength, ductility, and yield stress of the rock also increase.

Triaxial testing of rocks involves placing a rock sample in a pressure chamber under a three-dimensional stress state to measure its strength and deformation. Through testing, the failure envelope of the rock can be determined, and the cohesion (c) and internal friction coefficient can be calculated.

Xi'an Lichuang Material Testing Technology Co., Ltd. specializes in the production of rock triaxial testing machines. The company has obtained patented technology from the National Intellectual Property Administration (Patent No.: 0326278812). The design incorporates advanced technologies from similar equipment in the domestic and international industry, fully ensuring the stability and reliability of the system. It is an ideal, cost-effective testing equipment for research institutions and universities.

Main features and functions of the equipment:

1. The testing machine's control system can automatically calibrate the accuracy of the testing machine and automatically adjust to zero.

2. Test conditions, parameter settings, and test results are automatically saved by the system.

3. The computer fully digitally displays multiple engineering quantities such as load, displacement, deformation, and confining pressure. Multiple channels perform measurement, display, and control tasks in parallel and independently.

4. Multi-channel, multi-parameter, fully digital closed-loop control, automatically adjusting the system's PID values. High-resolution feedback sampling and signal conditioning technology are employed, with all channels performing synchronous feedback and data acquisition at a rate of 5kHz.

5. The system features intelligent management functions such as overload and failure protection.

6. The test control software runs in the Windows environment, with a user-friendly interface and simple operation. It can complete the setup of test conditions and sample parameters, as well as process test data. Test data can be saved in multiple file formats. After the test, data can be imported into software such as Word, Excel, and MATLAB for processing. Data analysis can be performed after the test, and test reports can be printed.

7. Uniaxial and triaxial compression tests under static and dynamic load conditions can be conducted to obtain the complete stress-strain curves of specimens under uniaxial and triaxial conditions.

The microcomputer-controlled electro-hydraulic servo rock triaxial testing machine is a new type of testing equipment that meets the requirements of modern geotechnical mechanics research and studies the mechanical properties of rocks (soils).
