Description of universal material testing machine

  This testing machine is suitable for multiple mechanical tests such as tension, compression, bending, bending resistance, peeling, tearing, shearing, puncture, low-key fatigue, etc. in the product, and can meet GB, ISO, JIS, ASTM, DIN, JG , JT, YB, QB, YD, YY, QC, SY, SL, BB, HG and other international standards and industry standards to test and provide data. With a powerful CNC display system and microcomputer control system, full LCD CNC settings are required Parameters, curves, displacements, and force values can be dynamically displayed on the LCD digital display, connected to a computer printer to realize full computer control and print standard test reports; the test data curve is dynamically displayed with the windows operating system, and the test data can be arbitrarily deleted. Curve operation is more convenient and easy. Curve traversal, overlay, separation, zoom printing and other full electronic display monitoring can be performed anytime and anywhere.

2. Working principle and performance of universal material testing machine:

Driven by a servo motor, the servo motor drives the moving beam to move up and down through a transmission mechanism to realize the test loading process. This machine uses an advanced fully digital closed-loop control system for control and measurement, and a computer for dynamic display of the test process and test curve, and data processing. After the test, the curve can be amplified by software for data analysis and editing.
