Computer Control Electro-hydraulic Servo Pressure Shear Testing Machine
Main functions
This machine is specially used for testing mechanical properties of finished plate rubber bearing of highway bridge. It can detect axial compression deformation and radial deformation under compressive elastic modulus test, shear elastic modulus test, allowable shear Angle test, ultimate compressive strength test, friction coefficient test, allowable Angle test and load test of basin rubber bearing of highway bridge. The precision of this machine is in line with JJG175 pressure and universal material testing machine verification requirements.
The main machine adopts four column structure, high rigid strength of the frame, easy to measure the elastic deformation of the sample. Microcomputer control automatic continuous steady load, load, automatic data acquisition, storage, map curve, automatic printing test report, can be made the bridge rubber bearing compressive elastic modulus test, shear elastic modulus test, shear adhesive properties, shear ageing, the coefficient of friction, Angle test, the ultimate compressive strength test, the permissible corner test.
