The electro-hydraulic servo dynamic fatigue testing machine (referred to as the testing machine) is mainty used to test the dynamic characteristics of métal, non-metal and composite materials at room température (or high and low température, corrosive environment). The testing machine can perform the following tests:
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, and angle.
The testing machine can realize sine wave, triangle wave, square wave, sawtooth wave, anti-sawtooth wave, puise wave and other waveforms, and can perform tensile, compression, bending, low-cycle and high-cycle fatigue tests. It can also be equipped with an environmental test device to complété environmental simulation tests at different températures.
The testing machine is flexible and convenient to operate. The moving beam lifting, locking, and specimen clamping are ail 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.
