Dynamic fatigue machines

ZwickRoell's electromechanical servo test actuators are versatile and can be used as flexible testing machines for a wide range of applications. They are ideal for both tensile and compression testing, and can be easily integrated into various test fixtures and customized to meet specific needs.

With these actuators, you can perform everything from material and component testing to testing of finished products. They are also ideal for verifying individual production steps such as joining, press-fitting, and assembly.

In addition, the actuators can handle fatigue testing with long stroke lengths, making them an excellent choice for advanced testing environments where high precision and repeatability are critical. They are powered by an AC motor and therefore require no hydraulics, making them easy to move between different applications.

With a ZwickRoell servo test actuator, you get a reliable, energy-efficient, and user-friendly solution to meet today's high standards for testing and quality control.

Vibrophore – Energy-Efficient Resonance Testing Machine for Fatigue and Static Testing
ZwickRoell’s Vibrophore is a high-frequency testing machine that combines resonance technology and electromagnetic drive to perform dynamic and static tests with high precision and low energy consumption. The machine is ideal for determining fatigue strength (HCF), service life, and fracture behavior in materials and components.

In its latest generation, the Vibrophore can also be used for static tensile and compression tests up to 1,000 kN, making it a truly multifunctional testing solution for both R&D and quality assurance.

Typical applications:

• Fatigue Testing of Bolts, Crankshafts, Piston Rods, Reinforcing Steel, and Concrete
• Fracture mechanics tests (CT/SEB specimens)
• Production Testing and Service Life Simulation of Dynamically Loaded Components

Vibrophore combines high performance with energy efficiency and low operating costs, making it a cost-effective choice for high-volume testing and advanced materials analysis.

Servo-hydraulic fatigue testing systems – maximum rigidity and reliability in dynamic testing
ZwickRoell's servo-hydraulic test frames are specifically designed for fatigue testing and crack growth analysis, where high measurement accuracy and frame rigidity are critical. They are used to determine material properties under cyclic loading, including:

• High-Cycle Fatigue (S-N) / Wöhler Curves
• Low-Cycle Fatigue (LCF)
• Fracture mechanics and fracture propagation

The test actuator can be mounted above or below the test area, depending on ergonomics and the type of test. The actuator features hydrostatic bearings, which provide very low friction, minimal wear, and a long service life—even under high loads and at high frequencies.

The systems are powered by separate hydraulic power units, which are available in various power ratings to suit your needs. With extremely high frame rigidity and a precision-controlled tool and load cell mount featuring a guide pin and flange, exceptional alignment and repeatability are achieved in all test sequences.

ZwickRoell's testing systems always come equipped with testControl II electronics and testXpert software, ensuring precise control, data acquisition, and analysis—all integrated and user-friendly.

ZRS is there to help you every step of the way—from configuration to installation, calibration, and long-term service.

HTM – High-Speed Tester for Materials Requiring Crash Data and Strain Rate Measurements
ZwickRoell's HTM series consists of advanced servo-hydraulic testing machines designed for high strain rates, ideal for applications where a material's fracture behavior is influenced by the loading rate—such as in crash, impact, or rapid deformation scenarios.

With test forces ranging from 25 kN to 160 kN and a maximum piston speed of 20 m/s, HTM machines enable reliable testing of materials and components under real-world loading conditions.

The system comes complete with a hydraulic power unit, high-precision sensors, testControl electronics, and testXpert software, providing a seamless and integrated testing solution—from specimen clamping to data analysis.

Thanks to its wide speed control range, HTM can be used for both slow and extremely fast test sequences, making it ideal for the development of constitutive models, simulations, and safety calculations in the automotive industry, aviation, packaging, and advanced materials research.
