Product Description

Product Description

Scope of application:
Electro-hydraulic servo dynamic fatigue testing machine is mainly used to test the dynamic and static mechanical properties of various materials, parts, elastomers, shock absorbers and components. Tensile, compression, bending, low cycle and high cycle fatigue, crack propagation and fracture mechanics tests can be carried out under sine wave, triangular wave, square wave, trapezoid wave and combined waveform. Environmental test devices can also be configured to complete environmental simulation tests at different temperatures.

Performance characteristics:
1, testing machine host: column, base, beam form a closed frame structure, frame stiffness, no reverse gap, good stability. The outer surface of the column is treated with hard chrome plating, the servo actuator (cylinder) is placed under, and the cylinder piston is designed with bi-directional action. The sample clamping adjustment is convenient and flexible.
2, hydraulic servo pump station: the use of no leakage quiet technology, stable pressure output, no fluctuation, low noise, good heat dissipation effect, high filtration accuracy, pressure overload, oil temperature overtemperature automatic protection.
3, control mode: force, displacement, deformation PID closed-loop control, and can achieve any control mode smooth without disturbance switching.
4, test software: suitable for Windows test platform operation and control system cooperation, can control the test system to complete all kinds of dynamic and static mechanical property tests, such as metal tensile, compression, bending, low cycle and metal fracture mechanics tests. And independently complete various test management, data storage, test report printing and other functions.
5, test waveform: sine wave, triangular wave, square wave, random wave, sweep wave, combined waveform, etc.
6, protection function: with oil circuit blockage, overtemperature, low liquid level, hydraulic system overload, motor overheating, preset fatigue times to, specimen fracture alarm shutdown function.

According to the criteria:
1, in line with GB/T2611-2007 "testing machine general technical requirements", GB/T16826-2008 "electro-hydraulic servo universal testing machine", JB/T9379-2002 "tensile fatigue testing machine technical conditions" requirements;
2, meet the GB/T3075-2008 "Metal axial fatigue test method", GB/T228-2010 "Metal material room temperature tensile test method" and other standards;
3, applicable to GB, JIS, ASTM, DIN and other standards.
