1. The YDW-300 series microcomputer controlled electronic rock direct shear tester is developed based on the industry standards (SL264-2001) "Rock Test Code for Water Resources and Hydropower Engineering" and (JTG E41-2005) "Rock Test Code for Highway Engineering". This testing machine is a new generation of rock and concrete testing equipment developed using dual channel AC servo motor drive technology (domestic), sensor technology, microcomputer control, and software processing technology. It can be used for direct shear testing of rock structural surfaces (such as joint surfaces, layers, slices, fissure surfaces, etc.), rock itself, and concrete or mortar rock bonding surfaces, as well as shear strength testing of concrete and other materials bonding surfaces. The experimental equipment has fully listened to the opinions of the engineering application department and the scientific research department, overcoming the disadvantages of traditional electro-hydraulic servo drive, such as instability, oil leakage, and high failure rate that are difficult to eliminate. The machine has a compact structure, beautiful style, simple maintenance, and easy operation. The entire experimental process can be automatically controlled by a microcomputer under Windows 2000/XP; Belonging to the domestic market and possessing international standards.

2. Dual channel AC servo motor loading closed-loop control (domestic and internationally recognized)

3. Similar products are currently used in: PetroChina Exploration and Development Research Institute, Geological Brigade of Jiangsu Provincial Institute of Geology and Mineral Resources

Product Features:

1. The computer screen displays parameters such as speed, force, displacement, etc., which are automatically analyzed and calculated in the database.

2. Real time recording of test curves during the experimental process, displaying and saving, and high-speed sampling;

3. The data and report processing function provides users with a report editing tool for graphic layout, which has the characteristics of flexible operation and easy learning. It can conveniently print test curves and test values;

4. The report can provide: shear stress shear displacement curve, shear stress normal displacement, shear stress normal stress curve, and can simultaneously display stress-strain curve, force time, force displacement curve, and other curves. The characteristic points on the curves can be extracted freely.

5. Real time display of current normal and tangential force values, peak values, experimental process information, current displacement, etc.

6. The software is equipped with an automatic reset system for displacement and force values, eliminating factors such as human reading errors.

7. Equipped with overload protection, when the force or displacement exceeds the rated theoretical value of the testing machine, it will automatically unload and stop the test.

8. The area, height, ambient temperature, and other parameters of each experiment can be changed or filled in according to the actual situation.

9. The experimental process can be edited on-site by the operator according to the actual situation, which is simple and convenient.

10. Directly calculate the values of C, Φ, and μ;

11. Software functionality, highly flexible.
