Dynamic Fatigue Testing Machines

Dynamic fatigue testing machines are designed to perform repeated cyclic loading on materials and components. Unlike universal testing machines which apply quasi-static loads to determine yield strength, tensile strength, and ultimate failure, fatigue testing systems typically load materials within the elastic range until failure occurs due to accumulated fatigue damage.

Typical test types include: High-cycle fatigue (HCF), Low-cycle fatigue (LCF), Fracture mechanics tests (including pre-cracked specimens) Dynamic fatigue testers may use various actuation technologies, including servo-hydraulic actuators, electrodynamic actuators, and linear motors.

Are dynamic fatigue testing machines suitable for evaluating the fatigue life of structural metals used in construction?

Yes. Dynamic fatigue testing machines feature a servo-hydraulic closed-loop control system combined with a high-stiffness load frame, enabling precise simulation of cyclic loading experienced by building steel structures. This allows accurate assessment of fatigue life, durability, and long-term structural reliability.

Metallurgical and mechanical manufacturers need to study the fatigue strength and fracture limits of metals. Can the fatigue testing machine achieve accurate cyclic control?

Absolutely. Dynamic fatigue systems are equipped with full-digital servo control and dynamic force closed-loop regulation, providing: High-precision stress or strain cycling; Long-duration, high-cycle operation; Excellent stability and repeatability.

Can dynamic fatigue testing machines simulate real-world service conditions for automotive and rail components (suspension parts, bearings, structural assemblies)?

Yes. Dynamic fatigue system uses high-frequency servo-hydraulic actuators and optional multi-channel synchronous control, enabling replication of complex real-world loading such as road-induced vibration, multiaxial fatigue loading, random loading spectra and long-cycle durability tests.

Are dynamic fatigue testers suitable for aerospace applications such as composite structures and crack-growth research?

Yes. Aerospace-grade fatigue systems offer high-frequency sinusoidal, triangular, random, and programmable loading. The tester features high-sensitivity force & displacement sensors, broad frequency bandwidth. This makes them ideal for composite fatigue lifetime studies, crack initiation and propagation (fracture mechanics), and high-cycle loading of aircraft structural components.

Can dynamic fatigue systems perform precise small-deformation cyclic testing required for rubber, elastomers, and polymers?

Yes. Dynamic fatigue testing machines are fully capable of performing precise small-deformation cyclic tests required for rubber, elastomers, and polymer components.
