YJG Electro-hydraulic Servo Compression Shear Testing Machine

1. Introduction:
This machine is specially used to test the mechanical properties of the finished products of highway bridge plates and vibration isolation rubber bearings. It can be subjected to compressive elastic modulus test, shear elastic modulus dynamic test, shear angle test, ultimate compressive strength test, friction coefficient test, corner test and axial compression deformation under load test of road bridge basin rubber bearing. And detection of radial deformation. The maximum positive pressure is 5000kN and the maximum horizontal shear force is 1000kN. The maximum corner force is 300kN. In particular, the measurement range is wide, that is, the positive pressure: 20 kN to 5000 kN, the horizontal shear force: 10 kN to 1000 kN, and the angular force is 12 kN to 300 kN. The accuracy of this machine is in line with JJG157 tensile force, pressure and universal material testing machine verification requirements.

2. Features:
The main frame adopts four-column structure, and the beam and the base adopt the integral casting structure. The rigid strength and structural stability of the frame are better than the two-column structure, which is convenient for measuring the elastic deformation of the sample. Microcomputer control automatically and continuously load smoothly, automatically load, automatically collect data, store and draw curves, automatically print test report, can carry out compressive elastic modulus test, shear elastic modulus test, shear bond of bridge rubber bearing Performance, shear aging, friction coefficient, corner test, ultimate compressive strength test, corner test.
