I. Overview:
Electro-hydraulic servo fatigue testing machine
■Tensile and compression test
■Crack growth test
The closed-loop servo control system composed of electric controller, servo valve, load sensor, displacement sensor, extensometer and computer can automatically and accurately control the test process, and automatically measure test parameters such as test force, displacement, deformation, torque, angle, etc. .
The testing machine can realize sine wave, triangle wave, square wave, sawtooth wave, anti-sawtooth wave, pulse wave and other waveforms, and can perform mechanical tests such as tension, compression, bending, low cycle and high cycle fatigue. It can also be equipped with an environmental test device to complete environmental simulation tests at different temperatures.
The testing machine is flexible and convenient to operate. The lifting, locking, and sample clamping of the moving beam are all completed by button operations. It uses advanced hydraulic servo drive technology to load, high-precision dynamic load sensors and high-resolution magnetostrictive displacement sensors to measure the force of the specimen. Value and displacement. The fully digital measurement and control system realizes PID control of force, deformation, and displacement, and smooth transition between each control. , The test software works in the WINDOWS XP/Win7 Chinese environment, with powerful data processing functions, test conditions and test results are automatically saved, displayed and printed. The test process is fully integrated into computer control. The test machine is an ideal cost-effective test system for scientific research institutes, metallurgical construction, national defense and military industry, colleges, machinery manufacturing, transportation and other industries.
