1. Purpose:

    PWS- 300 electro-hydraulic servo steel strand fatigue testing machine is mainly used for the fatigue life test of steel strands in GB/T5224, ISO6934 and other related standards. It can also be used for steel wires, steel rods and other related materials, various mechanical parts, and others. Dynamic and static mechanical performance test of metal materials and components By changing the fixture, the tensile, compression, high-cycle, low-cycle, fatigue crack test and research of materials and parts can be completed. This machine is equipped with special test clamping accessories for steel strands . According to different sample specifications, the corresponding clamping accessories are selected to complete the fatigue life test.
