Servohydraulic testing machines have universal application for materials and component testing under pulsating or alternating loads, with periodic or random signals. Quasi-static and dynamic loads are also easily achieved.
ZwickRoell's product portfolio includes a variety of testing machines for determining the fatigue life of components or complete products. These range from single testing actuators to servohydraulic testing machines for multi-axial fatigue tests. The force range is available from 5 to 2,500 kN.
The latest generation of Vibrophores (high-frequency pulsators) from ZwickRoell can be used as both dynamic and static materials testing machines—a first for this type of machine—with test loads up to 1,000 kN.
Typical applications for resonance testing systems are material fatigue tests and durability tests on standardized specimens and components (for example, piston rods, crankshafts, and screws), and production and quality control of components exposed to dynamic loads during their service life, such as concrete and reinforcing steel, as well as quasi-static tensile and compression tests and fracture mechanics tests on CT and SEB specimens.
The LTM electrodynamic testing machines are used to determine the durability of materials and components in the finite life fatigue and high cycle fatigue ranges.
The LTM’s wide speed range allows it to be used for both dynamic fatigue tests and quasi-static tests. The oil-free drive, combined with ease of installation, makes the electrodynamic testing machine ideal for use in biomedical engineering and electronics, as well as for research and training. Typical examples include tests on hip-joint and knee replacements and dental implants. Other applications are tests on standard plastics and composites specimens, as well as aluminum and plastics CT and SEB specimens.
