High frequency electromagnetic dynamic fatigue testing machine
Product function and purpose
It is mainly used to test the dynamic and static mechanical properties of various materials, parts, elastomers, shock absorbers and components. It can perform tensile, compression, bending, low and high cycle fatigue, crack propagation, and fracture mechanics tests under sine wave, triangle wave, square wave, trapezoidal wave, and combined waveforms. It can also be equipped with environmental testing devices to complete environmental simulation tests at different temperatures.
Performance features / advantages
● Test machine host: column, base, beam constitute a closed frame structure, frame stiffness, no reverse clearance, good stability. The outer surface of the column is electroplated with hard chromium, the servo actuator (oil cylinder) is placed downward, and the piston design of double acting oil cylinder is adopted. The sample clamping adjustment is convenient and flexible.
● Key components: adopt international famous brands such as MOOG servo valve of the United States, DOLI controller of Germany, Buer oil pump of Japan, Shiquan sensor of USA, displacement sensor of MTS company of USA, etc.
● Hydraulic servo pump station: adopt no leakage mute technology, stable pressure output, no fluctuation, low noise, good heat dissipation effect, high filtering accuracy, automatic protection of pressure overload and oil temperature over temperature.
● Control mode: force, displacement and deformation PID closed-loop control, and can realize smooth and undisturbed switching of any control mode.
● Test software: it is suitable for the operation and control system under the windows test platform. It can control the test system to complete all kinds of dynamic and static mechanical property tests, such as metal tensile, compression, bending, low cycle and metal fracture mechanical tests. And it can complete all kinds of test management, data storage, test report printing and other functions independently.
● Test waveform: sine wave, triangle wave, square wave, random wave, sweep frequency wave, combined waveform, etc.
● Protection function: it has alarm and shutdown functions such as blockage of oil circuit, over temperature, low liquid level, overload of hydraulic system, overheat of motor, preset fatigue times and fracture of test piece.
