Electro-hydraulic servo fatigue testing machine.

1. Main purpose and scope of use.

Electro-hydraulic servo fatigue testing machine meets the fatigue life of various specification materials. The extended configuration can be widely used in dynamic and static mechanical tests of materials and components, including tensile, compression and fatigue tests of materials and components.

Test software to work in the Winodws Chinese environment, should have a powerful data processing function, test conditions and test results saved automatically, display, print, comply with relevant national standard random group of test data, test curve and test report.

Electro-hydraulic servo fatigue testing machine has the advantages of convenient use, high precision and good reliability. Adopt the concept of "unitization, modularization and standardization". Actuators of the key parts were picked from the international and domestic famous brands of the same kind of product or finished in adopting international advanced technology and system has high stability and reliability of the overall performance and the international advanced product technology level.

This testing machine is also called dynamic and dynamic universal fatigue testing machine, which can be used for low-cycle fatigue test (0.01-50HZ), or static stretching, compression, bending, creep and other experiments. Dynamic fatigue test can realize random waveform, sinusoidal waveform, square wave, triangular wave, and other waveforms, and according to the strength of the sample, the frequency adjustable range is 0.01 ~ 50HZ. This machine in different fixture in order to realize the tensile, compression, shear and bend fatigue strength and fatigue life experiments, as well as a variety of materials including tensile, compression, bending, torsion, high, low cycle, creep and creep fatigue interaction such as biological mechanics performance test. High temperature strain and low temperature strain fatigue test can be carried out after configuration of high temperature furnace or environment box. It is suitable for the fatigue performance test of various materials and structural components in steel, automobile, machinery, resin, university and research institute.
