The YJW‐10000 Computer Control electro‐hydraulic servo compression shear testing machine adopts the oil cylinder bottom type, four column structure, the machine frame stiffness intensity is high, the distortion is small, meets the highway, the railroad bridge plate type, the basin type, the ball type support inspection request, the test space is stepless adjustable, to satisfy different height of the test requirements. Using the proprietary multi‐channel closed loop coordinated loading electro‐hydraulic servo control system based on Test Gold, the microprocessor control coordinated multi‐stage hydraulic loading, continuous loading steadily, multi‐stage test force maintenance, automatic collection and storage of data, drawing of curves, automatic printing test report, Computer timely control of the test process, showing the test force and test curve, simple and reliable operation.
This machine is used to test the mechanical properties of the rubber bearing of highway bridge. This could be done respectively on:
plate‐type bearing:
- Compressive elastic modulus test
- Ultimate compressive strength test
- Shear modulus test
- Shear bonding performance test
- Shear aging test
- Friction coefficient test
- Allowable angle test
- Basin bearing
- Vertical bearing capacity test of finished product bearing
- Friction coefficient test of finished product bearing
- Rotation test of finished product bearing
- Spherical steel bearing
- Vertical bearing capacity test of finished product bearing
- Friction coefficient test of finished product bearing
- Determination of rotational moment of finished product bearing
