Electro-hydraulic servo cross multi-axis fatigue testing machine

Microcomputer controlled electro-hydraulic servo multi-functional cross fatigue test system
1. Purpose
Microcomputer controlled electro-hydraulic servo multi-functional cross fatigue test system is mainly used for solder joint welding shear tensile fatigue test, cross tension test Tensile fatigue test, weld crack fatigue and other tests. This system can perform tension and compression fatigue tests, three-point bending fatigue tests, four-point bending fatigue tests, fatigue tests, and crack growth rate tests under sine waves, triangle waves, square waves, trapezoidal waves, ramp waves, and block waves. .
Meet standards, , ,B/-,B/3-,-,B/-related auto parts tests.
This test system adopts the electro-hydraulic servo controller (r) with microcomputer-controlled electro-hydraulic servo fatigue test control technology as the core, which is patented technology (patent number:) protected by the State Intellectual Property Office of Lichuang Company. The system is stable and Excellent performance, synchronized with the world, and easy to operate.
The test software works in a Chinese environment, has powerful data processing functions, automatically saves test conditions and test results, displays and prints random group test data, test curves, and test reports that comply with relevant national standards. It is widely applicable to It is an ideal cost-effective test system for scientific research institutes, metallurgical construction, national defense and civil air defense, colleges and universities, machinery manufacturing, transportation and other industries.
