The ways products are used in transport and energy technology place particular demands on the safety of the products and of components made from them. The material properties for fatigue strength and fatigue limit, which are determined in fatigue tests, frequently have a safety-relevant impact on the choice of material and design of parts. Specimens are tested under cyclic load conditions and under alternating tension-compression loading. Zwick offers fatigue testing machines with an electromagnetic drive up to 600 kN as standard. The largest servo-hydraulic testing machine currently in use can handle loads up to 5000 kN.
The behavior of round products under torsion is important in materials testing. For static testing, Zwick supplies drives, which when used in combination with materials testing machines, can apply torque to the specimen and determine the corresponding material properties. It is also possible to superimpose multiple load axes and test the material according to its use. For fatigue testing under high torque alternating load, frequencies up to over 200 Hz can be achieved in a high-frequency pulsator (Vibrophore) equipped with special test fixtures. Using resonance conditions means that the test is both quick and, due to extremely low power consumption, cost-effective. The advantages when testing with high-frequency pulsators (Vibrophore) are
