Medium Force Fatigue Test System BI-7020
The BI-7020 Medium Force Fatigue Test System is a high-performance servo-hydraulic testing platform designed for medium-force fatigue, fracture, and durability testing of materials and components. It combines a rigid two-column load frame, a servo-controlled actuator, and a digital closed-loop controller to deliver precision and repeatability in high-cycle and low-cycle fatigue testing applications.
With a dynamic force capacity of up to ±100 kN, the system supports a wide range of test modes including tensile, compressive, flexural, and crack propagation analysis. It features a standard actuator stroke of 150 mm, operates up to 100 Hz, and includes a high-speed data acquisition system that ensures accurate capture of transient events. The BI-7020 is ideal for industries such as automotive, aerospace, polymers, defense, construction materials, and industrial R&D labs.
