Brief introduction: GPS series of high-frequency fatigue testing machine is a kind of electromagnetic excitation type resonant fatigue testing machine, mainly used for metal materials and parts for high frequency alternating load under tensile, compression test and tension and compression fatigue properties and fracture mechanics performance test. Equipped with corresponding fixture, 3, 4 can be bent, compact tensile, plate specimen tensile, gears, bolts, connecting rod, chains, such as fatigue test, microstructure observation and crack growth rate, program-controlled loading test, etc. Features: 1. The machine work with high efficiency, easy to start up, low energy consumption and high control precision, low volatility, and easy to operate. 2. Intelligent digital pulse width modulator template, isolation type IGBT switch power amplifier unit, intelligent measuring force amplifier template. 3. The new host harmonic air-gap structure, easy to start up without having to manually voltage shift 4. The average load control system adopts imported high precision ac servo motor closed-loop control system 5. Alternating load closed-loop control, automatic compensation, there are two kinds of control mode: the conventional fatigue test (axial tension and compression is symmetric, asymmetric and single pulse test) and program-controlled loading test 6. Mode of operation: operation and set generated by the system software is a virtual panel 7. All control directly by the computer management and control, function Technical parameters: Maximum load: plus or minus 20 (kN) Biggest one-way pulse load: plus or minus 20 (N.m) Biggest alternating load: 10 (peak) Decay of multiple step: don't step The average relative error: load plus or minus 1% or less Volatility: alternating load plus or minus 0.5% F.S Average load volatility: plus or minus 0.5% F.S Frequency range: 80 ~ 250 (Hz) Chuck: the maximum distance between 500 (mm) Maximum distance between the two columns: 350 (mm) Host appearance: 660 * 460 * 460 (mm) H.W.D Electric cabinet appearance: 600 * 650 * 650 Host: weight about 1200 kg Electric cabinet: about 80 kg The machine power: 220 v, 500 w
