Fatigue testing machine is a machine mainly used for testing the fatigue performance of metals and their alloys under room temperature in tension, compression or alternating tension and compression loads.

　　The fatigue testing machine is characterized by high load, high frequency and low consumption, thereby shortening the test time and reducing the test cost.

　　The fatigue testing machine is used to determine the fatigue characteristics, fatigue life, and fatigue life of metals, alloy materials and their components (such as operating joints, fixed parts, spiral moving parts, etc.) at room temperature under tension, compression or alternating tension and compression loads. Pre-crack and crack growth test. After being equipped with corresponding test fixtures, the high-frequency fatigue testing machine can perform three-point bending test, four-point bending test, thin plate tensile test, thick plate tensile test, reinforced steel bar tensile test, chain tensile test under sinusoidal load Test, fixed connection test, connecting rod test, torsion fatigue test, combined bending and torsion fatigue test, interactive bending fatigue test, CT test, CCT test, gear fatigue test, etc.
