Servo hydraulic fatigue testing machine ±25kN ~ ±2000kN 0.01～50Hz tension torsion fatigue testing HDT-A
Electro-hydraulic servo fatigue machine > < hereinafter referred to as testing machine is mainly used for testing the metal, nonmetal and composite materials at room temperature (high or low temperature, corrosive environment) under the dynamic characteristics of machine test can be carried out as follows:
Tensile, compression, fatigue test
By the electric controller, servo valve, load sensor, displacement sensor, stretch meter, torque sensor and Angle sensor and the computer to form a closed-loop servo control system, can accurately control the test process automatically, and automatic measurement test force, displacement, deformation, test parameters, such as torque and Angle.
Tester can realize can realize sine wave, triangle wave, square wave, half sine wave and cosine wave, triangle wave, and square wave, waveform, such as tensile, compression, bending and torsion, can be low and high cycle fatigue mechanics test, etc.Environmental test equipment can be configured to complete environmental simulation tests at different temperatures.
Machine operation is flexible and convenient, moving beam lifting, lock, specimen clamping are completed by the button operation, the use of advanced hydraulic servo drive technology loading, high precision dynamic load sensor and a high-resolution magnetostrictive displacement sensor measurement specimen strength and displacement.All digital measurement and control systems realize force (or torque), deformation, displacement (or Angle) PID control, and smooth transition between each control.The test software works in WINDOWS XP/WINDOWS 7 Chinese environment, powerful data processing function, test conditions and test results automatic memory disk, display and print.Test process include all computer control, the machine is scientific research, metallurgy, construction, national defense war industry, colleges and universities, machinery manufacturing, transportation and other industries ideal cost-effective test system.
