Servo-hydraulic 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.
Zwick's product range includes a variety of testing machines for determining the fatigue limit of components or complete products. These range from single testing-actuators to servo-hydraulic testing machines for multiaxial fatigue tests and are available in a force range from 5 to 2500 kN. Also available from Zwick are Vibrophores for determination of fatigue strength. Fatigue limit can be determined for the tensile and compression limits of the component, as well as for the torsion limit.
