The Electric Fatigue Series Testing Machine includes a range of products such as uniaxial axial loading test models, tension‑torsion composite synergistic loading test models, and benchtop models. By matching different environmental devices and tooling fixtures, it can achieve a wide variety of application tests.
For room‑temperature applications, standard mechanical fatigue fixtures are provided. With this configuration, the machine can perform tension, compression, and fatigue tests on standard material specimens (bars/plates) under ambient conditions. Additionally, hydraulic or pneumatic fixtures may be selected to accommodate different specimen requirements.
When equipped with high‑temperature fixtures and corresponding environmental devices, the system performs fatigue tests under elevated temperature conditions. These include tension tests on threaded bars and pin‑hole plates, as well as compression tests on threaded bars.
Similarly, for high/low‑temperature testing, the machine can be configured with appropriate fixtures and environmental chambers. This setup enables tension (threaded bars/pin‑hole plates) and compression (threaded bars) fatigue tests on standard material specimens across a wide thermal range.
*Note: Standard material specimens should comply with the relevant requirements of Chapter 5 of GB/T 3075‑2008 “Metallic Materials – Fatigue Testing – Axial Force‑Controlled Method,” Chapter 6 of GB/T 15248‑2008 “Metallic Materials – Axial Constant Amplitude Low‑Cycle Fatigue Testing Method,” and Chapter 5 of GB/T 3354‑1999 “Test Method for Tensile Properties of Oriented Fiber‑Reinforced Plastics.”*
Finally, the Electric Fatigue Series Testing Machine is equipped with a comprehensive safety alarm system, enabling unattended operation during tests. The software allows upper and lower limit protections to be set independently for load and displacement; if exceeded, the host machine will stop working to ensure test safety. On the hardware side, the system monitors motor phase loss, motor overcurrent, and emergency stops. Should any of these protections be triggered, the system will automatically alarm or shut down.

The electric servo loading cylinder features three control modes: load, displacement, and deformation. Additionally, it can achieve sinusoidal loading and is used in tensile and compression testing systems for metallic or non-metallic materials. Moreover, it ensures both the accuracy and stability of static loading force values while achieving high linear velocity dynamic loading frequencies. Furthermore, the loading frame can be flexibly constructed to achieve various loading installation methods, making it an ideal product for research institutions and laboratories.
