廣州電子萬能材料拉力試驗機 組成
萬能材料試驗機是由測量系統(tǒng)、驅(qū)動系統(tǒng)、控制系統(tǒng)及電腦（電腦系統(tǒng)型拉力試驗機）等結(jié)構組成。
一.測量系統(tǒng)
1． 力值的測量
2． 變形的測量
3． 橫粱位移的測量
二.驅(qū)動系統(tǒng)
主要是用于試驗機的橫梁移動，其工作原理是由伺服系統(tǒng)控制電機，電機經(jīng)過減速箱等一系列傳動機構帶動絲桿轉(zhuǎn)動，從而達到控制橫梁移動的目的。通過改變電機的轉(zhuǎn)速，可以改變橫梁的移動速度。
三.控制系統(tǒng)
顧名思義，就是控制試驗機運作的系統(tǒng)，人們通過操作臺可以控制試驗機的運作，通過顯示屏可以獲知試驗機的狀態(tài)及各項試驗參數(shù)，若該機帶有電腦的話，也可以由電腦實現(xiàn)各項功能并進行數(shù)據(jù)處理分析、試驗結(jié)果打印。試驗機同電腦之間的通信一般都是使用RS232串行通信方式，它通過計算機背后的串口（COM號）進行通信，此技術比較成熟、可靠，使用方便。
四.電腦
用來采集和分析數(shù)據(jù)，進入試驗界面后，電腦會不斷采集各樣試驗數(shù)據(jù)，實時畫出試驗曲線，自動求出各試驗參數(shù)及輸出報表。
Form
Universal material testing machine is composed of measuring system, drive system, control system and computer (computer system type tensile testing machine).
I. measuring systems
Measurement of 1. force values
2. measurement of deformation
Measurement of displacement of 3. transverse beams
Two. Drive system
The utility model is mainly used for the crossbeam movement of the test machine, and the working principle of the utility model is that the motor is controlled by a servo system, and a series of transmission mechanisms, such as a motor and a reducer box, are used to drive the screw rod to rotate, so as to control the moving of the cross beam. By changing the speed of the motor, the moving speed of the beam can be changed.

As the name suggests, the system is to control the operation of the testing machine, people can use the console to control the operation of the testing machine, and the test parameters through the display screen can learn testing machines, if the machine with a computer, the computer can also realize the functions of data processing and analysis, test results of print. The communication between the tester and the computer usually uses the RS232 serial communication mode. It communicates through the serial port (COM number) behind the computer. This technology is mature, reliable and easy to use.
Four. Computer
To collect and analyze data and to enter the test interface, the computer will continuously collect a variety of test data, real-time test curve drawn, automatic test parameters and output statements.
