Execution standards and test types of compression shear testing machine

The microcomputer controlled electro-hydraulic servo compression shear testing machine (dynamic and static integrated machine) is mainly used for mechanical performance, damping performance, 

large deformation testing and inspection of rubber bearings for highway, railway, bridge, building vibration isolation rubber bearings, plate rubber bearings, bowl type bearings, and ball type bearings. 

It can conduct vertical bearing capacity test, friction coefficient test, rotational torque test, compressive elastic modulus test, shear elastic modulus test, ultimate compressive strength test, friction 

coefficient test, as well as axial compression deformation and radial deformation detection under rated load test of rubber bearings, compressive elastic modulus test, shear elastic modulus test, 

shear adhesion performance, shear aging, friction coefficient, ultimate compressive strength test.

This product adopts microcomputer control to coordinate multi-stage hydraulic loading, smooth continuous loading, multi-level test force maintenance, automatic data collection and storage, curve 

drawing, automatic printing of test reports, computer timely control of test progress, display of test force and test curve, simple and reliable operation, and easy operation. And high-precision force 

sensors are used to measure force, high-precision displacement sensors are used to measure displacement, and high-performance servo valve components are used to ensure stable and reliable 

performance of the entire machine.
