8874 BIAXIAL SERVOHYDRAULIC FATIGUE TESTING SYSTEM

(25 kN/100 Nm)

The Instron® 8874 is a compact tabletop biaxial servohydraulic testing system that meets the challenging demands of various static and dynamic tests. The system carries out axial, torsion, or combined axial-torsion tests. With the actuator in the upper crosshead and a lower t-slot table, the 8874 makes an ideal platform for testing a variety of medical devices, biomaterials, advanced materials, and other components testing.

FEATURES

• Double-acting servohydraulic actuator with force capacity up to ±25 kN (±5620 lbf) and torque capacity of ±100 Nm (880 in-lb)

• High-stiffness, precision-aligned load frame with twin columns and actuator in upper crosshead

• 100 mm (4 in) of usable axial stroke and ±130° of rotation

• Designed for both dynamic and static testing on a variety of materials and components

• Adjustable upper crosshead with hydraulic lifts and manual locks fitted as standard for easy adjustment of daylight

• Patented1 Dynacell™ load cell technology for faster testing and reduction of inertial errors

• Compact tabletop servohydraulic fatigue testing system frame requires less than 0.4 m² (4.3 ft²) of space

• Designed to be used with the 3520 Series of Hydraulic Power Units

• Compatible with a large range of grips, fixtures, chambers, video extensometers, protective shields, and other accessories

• Patented stiffness based tuning algorithm that enables users to tune a variety of specimens in seconds

CONTROLLER AND SOFTWARE

The 8874 is supplied with a two-axis digital 8800MT controller that provides full system control, including features such as stiffness based tuning, amplitude control specimen protect, 19-bit resolution across the full range of transducers, and adaptive control technology. It also allows access to WaveMatrix™3 Dynamic Testing Software, Bluehill® Software for axial static tests, and other application specific software, such as the Fracture Mechanics suite.
