Brief introduction: Electro-hydraulic servo dynamic fatigue tester, which can dynamically test, program control fatigue test of high and low cycle fatigue, also can undertake static constant rate and constant strain, constant stress under the control of test and all kinds of conventional mechanical properties test, still can fracture mechanics experiment was carried out, according to the need can also be part of the vibration and impact test, also on the broad range of materials or components on the fatigue life, crack propagation, fracture toughness testing and simulation, the actual safety evaluation of the specimens, working conditions, it has advantages can't be matched by any other kinds of testing machine, is the world's most respected international fatigue material testing equipment. The application of this equipment covers the aviation, aerospace, nuclear power, vehicles, ships and the commodity inspection, etc, are all related to the material performance evaluation in the field of the necessary equipment. Features: 1. The test host humanized design, simple operation 2. The sole sealing design technology, reduce the piston run any lower 3. The sensor, servo valve, pump, piping system, first-class quality, is the preferred global measurement experts 4. The filter precision is high, to ensure that the hydraulic oil clean 5. High and low voltage switch at random, with automatic protection function 6. A full digital control system, powerful Technical parameters The biggest dynamic test force: + 100 kn Maximum amplitude actuators: + 75 mm, precision value for 2% plus or minus 1% FS Deformation measurement precision, precision value for 2%, plus or minus 0.5% Frequency range: 0 ~ 50 hz Main test waveforms: sine wave, pulse wave, square wave, sawtooth wave and random wave (mainly supported by the controller) Maximum linear velocity dynamic testing: 50 mm/s Number of fatigue: 2 x106 arbitrary (set) The biggest test space: not less than 1200 mm The distance between the column: 533 mm Constant pressure servo pump specifications: traffic 52 l/min, 21 mpa The workbench effective height: 920 mm Frame stiffness: 2.6 x 108 N/m Exterior size: 1100 mm * 900 mm * 3200 mm total weight : 1600 kg
