Electrodynamic Fatigue Testing Machine

The electrodynamic fatigue testing machine is designed for high-precision dynamic and static characterization of small metallic and non-metallic specimens, components, elastomers, and vibration-damping elements.

Industries

biomedical engineering, aerospace, microelectronics, automotive, and consumer product.

Features
  • The load frame adopts a fully enclosed, high-stiffness architecture with zero backlash, ensuring excellent stability during high-frequency cyclic loading.
  • The servo actuator is bottom-mounted and driven by a double-acting, non-contact electrodynamic motor, offering a compact footprint, low noise, clean operation, and completely oil-free/maintenance-free performance.
  • The movable crosshead is electrically adjustable, allowing flexible configuration of the test space to accommodate different specimen sizes and loading requirements.

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.

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.

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.
