The high-frequency fatigue testing machine is used to measure the fatigue characteristics and fatigue of metal, alloy materials and their components (such as operating joints, fixed parts, spiral moving parts, etc.) at room temperature under tensile, compression or tensile and compression alternating load Life, prefabricated cracks and crack propagation tests. After equipped with corresponding test fixtures, the high-frequency fatigue testing machine can carry out three-point bending test, four-point bending test, thin plate tensile test, thick plate tensile test, reinforced steel strip tensile test, chain tensile under sinusoidal load Test, fixed part test, connecting rod test, torsional fatigue test, bending-torsion composite fatigue test, interactive bending fatigue test, CT test, CCT test, gear fatigue test.
(High frequency fatigue testing machine)
Resonance testing machine
The maximum load is 250 kN, the equipment selection is from 40KN-300KN, stroke to 8 mm, the operating frequency is 300 Hz, the equipment uses a unique MAGNODYN electromagnetic excitation system that uses resonance to generate vibration.
General performance characteristics:
• High reliability • Unmaintained hydraulic source and valve, pump or cooling system • Simple and easy operation • High frequency operation test throughout the test process • Low energy consumption • The software has many practical values ​​and user-friendly interface operation System high frequency fatigue testing machine
MAGNODYN excitation system This system consists of two parts, an electromagnet and a spring (elastic) fixed in the dynamic loading process. A small but constant air gap is required between the magnet and the operating independent static load system. The dynamic circle permits full operation and testing of stand-alone independent loading systems. The MAGNODYN system design allows specimens or components to use active power directly.
