The main function of the glass four-point bending test machine:
(1) Simultaneous measurement and display of force value, large deformation, small deformation, and displacement.
(2) The test speed is arbitrarily set. (from 0.001-500mm/min, stepless speed regulation)
(3) The test curve is displayed in real time, and the horizontal and vertical coordinates are automatically shifted.
(4) It can be set to automatically judge the crack or not and automatically return to the starting point or not. The fixed time stop can be set, the fixed load stops, the fixed deformation stops, and the fracture determination condition can be set.
(5) The data of a sample that has been made can be arbitrarily deleted.
(6) The curve can be arbitrarily scaled, printed, and parameter points (yield points, elastic segments, etc.) are selected on the curve.
The glass four-point bending tester forms a frame structure by a high-precision ball screw. The all-digital AC servo motor driver is driven by the machine reducer and the Japanese synchronous gear belt to drive the high-precision, gap-free ball screw to move up and down. It has the characteristics of reasonable structure, large rigidity, stable loading and good stability. The data processing analysis is carried out by PC, and the test results can be automatically saved. After the test, the test song can be recalled, the test process can be reproduced through the curve, or the curve comparison and curve enlargement can be performed. The test software under Windows and Vista platform has strong data and graphics processing functions, which can print out complete test reports and test curves in real time.
