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.
Equipped with standard room-temperature mechanical fatigue fixtures, it can perform tests such as tension, compression, and fatigue on standard material specimens (bars/plates) under room-temperature conditions. To meet different specimen requirements, hydraulic fixtures or pneumatic fixtures can be equipped.
Equipped with standard high-temperature fixtures and high-temperature environmental devices, it can perform tests such as tension (threaded bars/pin-hole plates) and compression (threaded bars) fatigue on standard material specimens under high-temperature conditions.
Equipped with standard high/low-temperature fixtures and high/low-temperature environmental devices, it can perform tests such as tension (threaded bars/pin-hole plates) and compression (threaded bars) fatigue on standard material specimens under high/low-temperature conditions.
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.”
The Electric Fatigue Series Testing Machine is equipped with a comprehensive safety alarm system, enabling unattended operation during tests. The software can set upper and lower limit protections for load and displacement respectively. If the limits are exceeded, the host machine will stop working to ensure test safety. The hardware can monitor motor phase loss, motor overcurrent, emergency stops, etc. If any of these protections are triggered, the system will automatically alarm or shut down.
