20kN Fatigue Testing Machine
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.
