Micro -controlled servo pulse fatigue test machine
Microcomputer-controlled electro-hydraulic servo pulsation fatigue testing machine is mainly used for unidirectional pulsation and bending fatigue tests on various larger parts, components and components. Pulsation fatigue tests can be performed on various bridges, trusses, automobile chassis, front axles, rear axles, rolling stock and various reinforced concrete components. The testing machine produces periodic unidirectional pulsation within a certain range to realize the dynamic fatigue test of sine wave. The working frequency can be selected arbitrarily within the range of 2~8Hz, and the high-speed data acquisition technology is adopted to realize the high-speed data acquisition and closed-loop control of the system; the screen displays the static test force, the upper and lower peak values of the dynamic test force (direct reading), test waveform and test Frequency, test times, printer print test report; test data can be stored in the form of ASCII code, so that users can perform secondary data processing; digital zero-adjustment and calibration, digital input and output and other functions; the testing machine has overload, over-setting, Insufficient lubrication, the number of tests is over, the vibration of the sample fracture and other alarms or shutdown protection and other functions.
