The equipment adopts branded microcomputers to control high-precision electro-hydraulic servo pumps, drive precision hydraulic cylinders, absorb advanced testing machine control technology from Shimadzu Testing Machine Company in Japan, and automatically control the test force and displacement (deformation) in multiple modes according to national standards. It completes the setting of test parameters, control of the test process, data acquisition, processing, analysis and display, precise and accurate control and measurement of constant velocity displacement control and constant velocity test force control, and has the function of setting and maintaining any test force point. And equipped with Windows electro-hydraulic servo horizontal testing machine dedicated software, the performance parameters of the test piece are measured according to national standards or user provided standards, and the test data is statistically analyzed and processed. Then, various required test curves and test reports are output and printed. Test curves such as stress-strain, test stress-strain, test force time, test force displacement, displacement time, deformation time, etc. can be selected, and real-time display, amplification, comparison, traversal functions and monitoring of the test process can be achieved. Intelligent and convenient.
The testing machine adopts a double frame structure, with hydraulic cylinders installed on fixed crossbeams. Sensors are directly connected to the moving crossbeam to conduct tensile tests on the specimens, simplifying the structure of the loading machine head; The side of the hydraulic cylinder is equipped with a photoelectric encoder for measuring the deformation of the sample.
The side of the host is equipped with a hydraulic loading system, which uses low-noise hydraulic pump units, hydraulic valve groups, and high-precision AC servo motors to ensure high-precision, high-efficiency, low-noise, and fast response of the system, achieving automatic control of loading and reversing of the test; By adopting a sensitive pressure compensation system control, the hydraulic system structure is greatly simplified and the noise is lower. Under non full load working conditions, it basically works "quietly" without the need to add a cumbersome cooling system or isolate the hydraulic system from other rooms to isolate noise; The system is concise and clear.
