The RIG-T213 Dynamic and Static Stiffness Testing Machine is a high-precision electro-hydraulic servo test system designed for dynamic and static stiffness testing of various rubber bushing products. It is engineered for reliable force and displacement control, high-frequency testing, and stable long-term operation in laboratory and industrial testing environments.

This testing machine consists of a main frame, control system, and hydraulic system. The main unit adopts a dual-column steel frame structure with a compact and rigid design, low foundation requirements, and convenient installation. The actuator uses a hydrostatic support structure, which offers low friction, smooth low-speed motion, and stable high-speed performance. Key components such as the servo actuator, servo valve, displacement sensor, and load sensor are imported to ensure high accuracy, long service life, and dependable performance.

The digital servo control system features real-time motion control with fast response and precise data acquisition. The machine supports synchronized collection of force, displacement, and temperature data, making it suitable for demanding test applications involving rubber bushings and related components. With a maximum static load of 20 kN, maximum frequency of 100 Hz, and actuator stroke of ±50 mm, the RIG-T213 provides a practical solution for advanced material and component stiffness testing.
