The microcomputer controlled electro-hydraulic servo shear testing machine adopts a cylinder down type and four column structure, with high frame stiffness and strength, small deformation, meeting the detection requirements of plate, bowl, and ball bearings for highway and railway bridges. The testing space is infinitely adjustable, making it convenient for testing needs at different heights. Adopting the proprietary multi-channel closed-loop coordinated loading electro-hydraulic servo control system independently developed by Zhenzhen, the system is controlled by a microcomputer to coordinate multi-stage hydraulic loading, smooth continuous loading, and multi-level test force maintenance. It automatically collects and stores data, draws curves, and prints test reports. The computer controls the test process in a timely manner, displays test forces and curves, and has simple and reliable operation.
This machine is used for testing the mechanical properties of finished rubber bearings for highway bridges. Can be done separately:
1. Plate type support
Compressive modulus of elasticity test
Ultimate compressive strength test
Shear modulus of elasticity test
Shear adhesion performance test
Shear aging test
Friction coefficient test
Allowable turning angle test
2. Basin type support
Vertical bearing capacity test of finished bearings
Friction coefficient test of finished bearings
Finished support rotation test
3. Spherical steel support
Vertical bearing capacity test of finished bearings
Friction coefficient test of finished bearings
Measurement of rotational torque of finished bearings
4. This product can also undergo the tests specified in the national standards for railway bridge slab, bowl, and ball bearings.
