HWS Electro-hydraulic Servo Fatigue Testing Machine
Application：
This series computer Control Electro-hydraulic Servo Fatigue Testing Machine is ainly used to detect a variety of metals, non-metallic materials and small movable member, the static mechanical properties test. It can do tensile, compression, bending, low cycle and high cycle fatigue, crack growth, fracture mechanics test under sine, triangle, square wave, trapezoidal wave, random wave, combination waveform.This Test machine is flexible, moving beam down, locking the sample holder by button operations, the use of advanced hydraulic servo drive technology loaded, high precision and high resolution dynamic load sensor magnetostrictive displacement sensor specimens force values and displacement.
Fully digital measurement and control system implementation force, displacement, deformation closed loop control, test software under WINDOWS Chinese working environment, powerful data processing capabilities, test conditions and test results are automatically saved, displayed and printed. Fully integrated into the computer-controlled test procedure, the test machine is a research institutes, metallurgy building, defense industry, universities, machinery manufacturing, transportation and other industries ideal cost-effective test systems.
