Servo-hydraulic Testing Machines for Determination of Fatigue Limit

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.

Overview of fatigue limit testing at Zwick

An individually tailored modular system covering all testing requirements for determination of fatigue limit is available from Zwick. The system comprises actuators, hydraulic power-packs, distribution units, dynamic testing machines and other accessories. Powerful measurement and control electronics are on hand in the form of testControl II, with support provided by Zwick's testXpert II testing software during set-up and performance of dynamic tests for determination of durability. Individually tailored fatigue testing solutions are always available in addition to standardized products.

Decades of fatigue testing experience

The name of Zwick is automatically associated with static testing machines. However, Zwick has for several years been active in the field of servo-hydraulic testing technology for use in fatigue testing and determination of fatigue limit and is steadily expanding its product portfolio. Today Zwick has a comprehensive range of products for testing materials and components. Customers in research and science rely on Zwick testing technology for determination of the fatigue limit of standard components and for fatigue-testing larger, more complex components and complete products.
