The PWS Series Electro-hydraulic servo fatigue testing machine is used to test the dynamic characteristics of metals, non-metals, and composite materials under room temperature (or high/low temperatures and corrosive environments). The machine can conduct tension and compression tests.
The closed-loop servo control system, which consists of an electrical controller, servo valve, load sensor, displacement sensor, extensometer, and computer, automatically and accurately controls the test process and measures parameters such as test force, displacement, deformation, torque, and angle.
The machine is capable of generating sinusoidal waves, triangular waves, square waves, sawtooth waves, etc. It can perform tension, compression, bending, low-cycle, and high-cycle fatigue tests. An environmental testing device can also be configured to simulate different temperature conditions.
The machine features flexible and easy operation, with vertical beam lifting, locking, and specimen clamping all performed via buttons. Advanced hydraulic servo drive technology is used for loading, with high-precision dynamic load sensors and high-resolution magnetostrictive displacement sensors for measuring the specimen's force and displacement.
The fully digital measurement and control system allows PID control of force, deformation, and displacement, with smooth transitions between control modes. The testing software operates in a Windows Win7/Win10/Win11 environment, offering powerful data processing capabilities. Test conditions and results are automatically saved, displayed, and printed. The entire test process is controlled by the computer. This machine is an ideal, cost-effective testing system for scientific research institutions, metallurgy and construction industries, national defense, higher education, mechanical manufacturing, and transportation industries.
