广州电子万能材料拉力试验机  组成

万能材料试验机是由测量系统、驱动系统、控制系统及电脑（电脑系统型拉力试验机）等结构组成。

一.测量系统
1． 力值的测量

2． 变形的测量

3． 横粱位移的测量

二.驱动系统 
主要是用于试验机的横梁移动，其工作原理是由伺服系统控制电机，电机经过减速箱等一系列传动机构带动丝杆转动，从而达到控制横梁移动的目的。通过改变电机的转速，可以改变横梁的移动速度。 
三.控制系统 
顾名思义，就是控制试验机运作的系统，人们通过操作台可以控制试验机的运作，通过显示屏可以获知试验机的状态及各项试验参数，若该机带有电脑的话，也可以由电脑实现各项功能并进行数据处理分析、试验结果打印。试验机同电脑之间的通信一般都是使用RS232串行通信方式，它通过计算机背后的串口（COM号）进行通信，此技术比较成熟、可靠，使用方便。 
四.电脑 
用来采集和分析数据，进入试验界面后，电脑会不断采集各样试验数据，实时画出试验曲线，自动求出各试验参数及输出报表。

Form
Universal material testing machine is composed of measuring system, drive system, control system and computer (computer system type tensile testing machine).

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.
Three. Control system
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.
