The equipment is mainly used for compression, shear and corner performance tests of various types of seismic isolation, seismic and structural function devices, both for testing existing structural bearings and components and for research and development tests of new types of bearings and components in the future.

This testing machine adopts four columns, vertical oil cylinder top-mounted structure. Host structure is reasonable, good rigidity, safe and reliable. The base and beam of the main machine are made of cast steel, the vertical actuator is a single-cylinder structure, the whole machine adopts bolt shear-free structure, the vertical and horizontal steel body is stressed, avoiding bolt shear force causing bolt loosening, frame deformation, stress parts gap and safety accidents. Embedded lateral reaction plate and the mainframe frame cooperate to form a high-strength, high-rigidity vertical and horizontal self-reaction loading frame. The horizontal dynamic shear system adopts single outlet rod servo actuator, and the actuator adopts low damping large gap design technology to ensure good dynamic performance; the horizontal dynamic controller SYMTS controller, with high control accuracy and fast response. Control system with full digital electro-hydraulic servo control technology as the core, vertical, horizontal, corner multi-channel control; computer fully automatic data processing, and drawing test curve. The machine has a reasonable structural design, large test space and convenient for loading and clamping specimens.
