Main functions of the controller for fatigue test control.

Main functions of the controller for fatigue test control:

L can realize the dynamic and static closed-loop control of test force and displacement and smooth switching of control mode;

L controller can independently complete the PIDF closed-loop dynamic test control of the force or displacement channel, that is, the dynamic test is carried out with a certain test force or test displacement/deformation, test frequency and signal type. During the test, new test parameters can be modified without interrupting the test. At the same time, the controller can also be used to control static tension/compression tests, such as constant test loading rate or constant displacement/deformation rate test, various long-term holding tests or oblique wave combination tests.

L It can not only control the start and stop of oil source, switch between high and low pressure, but also complete the functions of parameter calibration, zero clearing, parameter storage and loading of various sensors;

L has a variety of control modes (force, displacement control, etc.), and can realize smooth and undisturbed switching of control modes; It has the functions of starting without fluctuation, software zeroing, saving and restoring PID settings, saving and restoring test files, automatically calibrating sensors, collecting data and protecting samples during the test.

The application of multifunctional software can quickly create and save the required test sequence, run the predefined tests and improve the test efficiency. The types of test process defined by software include: electro-hydraulic servo valve control instruction, data acquisition process, monitoring of test signal, external equipment control signal, program control process and operator prompt information. The graphical user interface operated by mouse is convenient to operate; The flexible data analysis function can save the test data obtained from the test according to the standard format, analyze the data, draw the test curve or write the test report as needed, and facilitate users to use other commercial software for analysis.
