Electro-hydraulic servo fatigue testing machine

Function summary:

       Electro-hydraulic servo fatigue testing machine is a high-precision and multi-purpose testing machine for fatigue performance testing of various metal materials, non-metallic materials, composite materials, polymer materials, structural parts, etc。With different fixtures, mechanical tests such as pulling, pressing and pressing can be carried out。Additional environmental test equipment can be configured to complete environmental simulation tests under high temperature, low temperature, salt spray and corrosion。
       All Chinese Windows platform test software, can carry out sine wave, triangular wave, trapezoid wave, custom wave and other fatigue curve test。Real-time dynamic display Real-time display force-time curve, displacement-time curve, deformation (need to be equipped with extensometer) -time and other test curves。The data can be processed and analyzed, the test results can be automatically saved, the test curve can be re-pulled after the test, and the curve can be analyzed, for example, the test process can be reproduced by the curve, or the curve can be compared and enlarged。
