It is mainly used to test the mechanical properties of rubber bearings and shock absorbers. It can be used to carry out compressive strength test, compressive elastic modulus test, shear elastic modulus test, shear adhesion performance test, shear aging test, friction coefficient test and rotation angle test for rubber bearings; The vertical bearing capacity, friction coefficient, rotation test and Teflon plate friction coefficient test of the basin type finished bearing of the bridge; the vertical bearing capacity, friction coefficient and rotation performance test and detection of the ball type bearing. The main engine can be used as a press alone, and can complete the compression test of the pier or the cement component with large structure size. The axial positive pressure is composed of four column pressure tester, which consists of loading cylinder, load sensor, four point displacement (deformation) measuring device set, screw rod, base, moving beam, hydraulic driving system and compression device; The horizontal shear force is composed of horizontal shear test device, horizontal load cylinder, load sensor, displacement sensor, horizontal pull plate, trolley bracket, etc. Angle force is composed of angle assembly. It is composed of loading cylinder, load sensor, angle plate, etc. In the control part, the full digital closed-loop control system is adopted; the control range is wide, the functions are multi-functional, and all operations are keyed; the closed-loop control functions such as test force, deformation and displacement can be realized, and the automatic and accurate control of the experimental process and the measurement of test force, displacement and deformation and other test parameters can be realized.
1. The machine has novel structure, humanized design, small occupation space, simple operation and easy
   maintenance;
2. Compact structure, good rigidity;
3. Powerful function and accurate test data;
4. The beam and shear device can walk automatically, and the test space is easy to adjust;
5. The load sensor is used in the force measuring system, which can fully ensure the accuracy and reliability of the
   test data. The load has the characteristics of no gear in the whole process, and the performance is superior;
6. The control system has three closed-loop control modes of load, displacement and deformation, which can be
   used for constant load, displacement and deformation test. In the test process, the non impact conversion can be
   realized among the three control modes;

7. Set the loading speed arbitrarily according to the requirements of the test within the allowable range of the
   testing machine; 8. The hydraulic system adopts the imported servo valve with fast response and high control accuracy, and the two
   servo channels work harmoniously without affecting each other
