PDW-series fatigue testing machines are mainly used to test the dynamic and static mechanical properties of various materials, components, elastomers, rubber elastomers and shock absorbers. It can conduct tension, compression, bending, low-cycle and high-cycle fatigue, crack growth, and fracture mechanics tests under sine waves, triangle waves, square waves, trapezoidal waves, ramp waves, and user-defined waveforms. Environmental chambers such as high-temperature furnaces, low-temperature chambers, and corrosion chambers can be equipped according to special requirements to complete mechanical testing of materials in different environments. It is widely used in automobile parts, rail vehicles, aerospace, ships, military industry and other fields.
Product Overview
The PDW-series fatigue testing machine is mainly used for testing the dynamic and static mechanical properties of various materials, components, elastomers, rubber elastomers, and shock absorbers. It can perform tensile, compression, bending, low-cycle and high-cycle fatigue, crack propagation, and fracture mechanics tests under sine wave, triangular wave, square wave, trapezoidal wave, oblique wave, and user-defined waveforms. It can also be equipped with environmental chambers such as high-temperature furnaces, low-temperature chambers, and corrosion chambers according to special requirements to complete mechanical testing of materials under different environments. It is widely used in automotive parts, rail vehicles, aerospace, shipbuilding, and military industries.
1.The actuator adopts a two-way hydraulic cylinder design, with a reasonable space layout and convenient operation.
2.The moving crossbeam lifting, locking, and sample clamping are all operated by buttons, which are flexible and convenient.
3.Automatic control, measurement, data acquisition and processing, plotting and printing of test curves and test reports
4.Automatic calibration and zeroing of the measurement and control system.
5.Stepless speed regulation, the control speed and control mode can be smoothly switched and maintained at will during the test.
6.Data storage and curve magnification, different test curves can be displayed at will during the test.
7.During automatic program operation, it can be switched to manual control at any time, and the control mode and control speed can be manually adjusted.
