Technical information of high frequency fatigue testing machine

SSIST imported high frequency fatigue testing machine

First, the definition of high frequency fatigue testing machine-
The high-frequency fatigue testing machine is used to measure the fatigue characteristics and sn 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. Fatigue life, precast 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, etc.
Second, the high-frequency fatigue testing machine-machine working principle
1. The machine is a static load, specimen, structure, and dynamic loading superimposed to produce resonance.
2. Dynamic loading is loaded by resonance generated by the natural frequency of the resonance system (resonator). The vibration system includes the structural quality of the machine and the spring and the part of the specimen being tested.
3. The resonator is an important device for resonance and resonance caused by the electromagnet system.
4. The resonance power consumption is very low (typically 20 to 500 watts), the operating frequency is in the range of 50 to 600 cps, the efficiency is more than 50 times that of other test machines, and the power consumption is only one tenth of the hydraulic machine.
Third, the application of high frequency fatigue testing machine
1. Fatigue life testing of fasteners and engine connecting rods
2. Fatigue life test of chain
3. Fatigue life of the piston, etc.
4. Fatigue life and strength test of gears
