The working principle of electronic universal material testing machine
The design of the mainframe and auxiliary equipment of the electronic universal testing machine draws on the technology of Shimadzu, Japan, with beautiful appearance, convenient operation, stable and reliable performance. The electronic tensile testing machine is composed of a measuring system, a driving system, a control system, and a computer. The working principles are as follows: The deformation measurement is measured by a deformation measuring device, which is used to measure the deformation of the sample during the test. There are two chucks on the device, which are connected to the photoelectric encoder mounted on the top of the measuring device through a series of transmission mechanisms. When the distance between the two chucks changes, the shaft of the photoelectric encoder is driven to rotate, and the photoelectric encoder There will be pulse signal output. The signal is processed by the single-chip microcomputer, and the deformation of the sample can be obtained. The principle of beam displacement measurement is roughly the same as that of deformation measurement. The displacement of the beam is obtained by measuring the number of output pulses of the photoelectric encoder. The driving system is mainly used for the movement of the beam of the testing machine. Its working principle is that the servo system controls the motor. The motor drives the screw through a series of transmission mechanisms such as a gearbox to achieve the purpose of controlling the movement of the beam. By changing the speed of the motor, the moving speed of the beam can be changed. The control system, as the name implies, is a system that controls the operation of the testing machine. People can control the operation of the testing machine through the console. The status of the testing machine and various test parameters can be obtained through the display screen. If the machine is equipped with a computer, it can also be controlled by the computer. Realize various functions and perform data processing and analysis, and print test results. The communication between the testing machine and the computer generally uses RS232 serial communication, communicating through the serial port (COM number) on the back of the computer. This technology is relatively mature, reliable and easy to use. The computer host is used to collect and analyze data. After entering the test interface, the computer will continuously collect various test data, draw test curves in real time, automatically calculate various test parameters and output reports.
