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。

开关机注意事项:

1开机时主机和计算机的开机顺序会影响计算机的通讯初始化设置，所以务必请用户严格按照上述开机顺序进行。

2每次开机后要预热5分钟，待系统稳定后，才可进行试验工作。

3如果刚刚开机，需要再开机，至少保证1分钟的间隔时间。

4在更换夹具后，首先要注意调整好可调挡圈（上下限位开关）。

5尤其在用小力值传感器做试验时，一定要调整好可调挡圈的位置，以免操作失误而损坏小力值传感器。不要超过传感器的额定量程。

6任何时候都不能带电插拨电源线，否则很容易损坏电气控制部分。

7试验过程中，不能远离试验机。

8试验过程中，除停止按键和急停开关外，不要按控制盒上的其它按键，否则会影响试验。

9试验结束后，一定要关闭所有电源。

10本计算机是专门用于试验机控制和数据处理的，请勿在计算机内安装其它应用软件，以免试验机应用软件不能正常运行。

11计算机要严格按照系统要求一步一步退出，正常关机，否则会损坏部分程序，导致软件无法正常使用。

12不要使用来历不明或与本机无关的软盘在试验机控制用计算机上写盘或读盘，以免病毒感染。

Note on and off:

1 The boot order of the host and the computer will affect the communication initialization Settings of the computer, so be sure to strictly follow the above boot order.

2 Preheat for 5 minutes after each startup, and test work can be carried out only after the system is stable.

3 If you have just started the machine and need to start it again, ensure that the interval is at least 1 minute.

4 After replacing the fixture, first pay attention to adjusting the adjustable stop ring (upper and lower limit switch).

5 Especially when testing with a small force value sensor, it is necessary to adjust the position of the adjustable stop ring to avoid damage to the small force value sensor due to misoperation. Do not exceed the rated range of the sensor.

6 Do not plug or dial the power cord at any time, otherwise it is easy to damage the electrical control part.

7 During the test, do not stay away from the testing machine.

8 During the test, except for the stop button and the emergency stop switch, do not press other keys on the control box, otherwise it will affect the test.

9 After the test, be sure to turn off all power supplies.

This computer is specially used for testing machine control and data processing, do not install other application software in the computer, so as to avoid the normal operation of the testing machine application software.

11 The computer must exit step by step in strict accordance with the system requirements and shut down normally. Otherwise, some programs will be damaged and the software cannot be used normally.

12 Do not use floppy disks of unknown origin or unrelated to the machine to write or read disks on the test machine control computer to avoid virus infection.

（二）特殊测试项目：
1.弹性系数即弹性杨氏模量定义：同相位的法向应力分量与法向应变之比。为测定材料刚性之系数，其值越高，材料越强韧。
2.比例限：荷重在一定范围内与伸长可以维持成正比之关系，其醉大应力即为比极限。
3.弹性限：为材料所能承受而不呈永久变形之醉大应力。
4.弹性变形：除去荷重后，材料的变形完全消失。
5.永久变形：除去荷重后，材料仍残留变形。
6.屈服点：材料拉伸时，变形增快而应力不变，此点即为屈服点。屈服点分为上下屈服点，一般以上屈服点作为屈服点。屈服（yield）：荷重超过比例限与伸长不再成正比，荷重会突降，然后在一段时间内，上下起伏，伸长发生较大变化，这种现象叫作屈服。
7.屈服强度：拉伸时，永久伸长率达到某一规定值之荷重，除以平行部原断面积，所得之商。
8.弹簧K值：与变形同相位的作用力分量与形变之比。
9.有效弹性和滞后损失：在复合材料拉力试验机上，以一定的速度将试样拉伸到一定的伸长率或拉伸到规定的负荷时，测定试样收缩时恢复的功和伸张时消耗的功之比的百分数，即为有效弹性；测定试样伸长、收缩时所损失的能与伸长时所消耗的功之比的百分数，即为滞后损失。

★ Tensile stress ★ tensile strength

★ Tensile strength ★ tensile elongation

★ Constant elongation stress ★ constant elongation

★ Constant stress force value ★ Tear strength

★ Arbitrary point force value ★ arbitrary point elongation

★ Extraction force ★ Adhesive force and take the peak value of calculation

(1) Common test items: (common display value and calculated value)

● Constant elongation at constant stress ● Constant stress force value ● Tearing strength

● Arbitrary point force value ● arbitrary point elongation ● Withdrawal force ● Adhesive force and take the peak calculated value

● Pressure test ● Shear stripping force test ● Bending test ● Extraction force puncture force test

(2) Special test items:

1. Elastic coefficient is defined as elastic Young's modulus: the ratio of normal stress component and normal strain in the same phase. To determine the coefficient of material rigidity, the higher the value, the stronger the material.

2. Proportional limit: the load can be maintained in direct proportion to the elongation within a certain range, and the large stress is the ratio limit.

3. Elastic limit: the great stress that the material can withstand without permanent deformation.

4. Elastic deformation: After removing the load, the deformation of the material completely disappears.

5. Permanent deformation: After removing the load, the material remains deformed.

6. Yield point: When the material is stretched, the deformation increases and the stress remains unchanged, which is the yield point. Yield points are divided into upper and lower yield points, and generally the above yield points are used as yield points. yield: the load exceeding the proportional limit is no longer proportional to the elongation, the load will drop suddenly, and then over a period of time, up and down, and the elongation will change greatly, this phenomenon is called yield.

7. Yield strength: when stretching, the load of permanent elongation reaching a specified value is divided by the original fault area of the parallel part.

8. Spring K value: the ratio of the force component in phase with deformation to deformation.

9. Effective elasticity and hysteresis loss: In the composite tensile test machine, when the sample is stretched to a certain elongation or stretched to a specified load at a certain speed, the percentage of the ratio of the work recovered when the sample is contracted and the work consumed when stretched is measured, that is, the effective elasticity; The percentage of the ratio between the energy lost during the elongation and contraction of the sample and the work consumed during the elongation is the hysteresis loss.
