控制系統(tǒng) 
顧名思義，就是控制試驗(yàn)機(jī)運(yùn)作的系統(tǒng)，人們通過(guò)操作臺(tái)可以控制試驗(yàn)機(jī)的運(yùn)作，通過(guò)顯示屏可以獲知試驗(yàn)機(jī)的狀態(tài)及各項(xiàng)試驗(yàn)參數(shù)，若該機(jī)帶有電腦的話，也可以由電腦實(shí)現(xiàn)各項(xiàng)功能并進(jìn)行數(shù)據(jù)處理分析、試驗(yàn)結(jié)果打印。試驗(yàn)機(jī)同電腦之間的通信一般都是使用RS232串行通信方式，它通過(guò)計(jì)算機(jī)背后的串口（COM號(hào)）進(jìn)行通信，此技術(shù)比較成熟、可靠，使用方便。

開(kāi)關(guān)機(jī)注意事項(xiàng):

1開(kāi)機(jī)時(shí)主機(jī)和計(jì)算機(jī)的開(kāi)機(jī)順序會(huì)影響計(jì)算機(jī)的通訊初始化設(shè)置，所以務(wù)必請(qǐng)用戶嚴(yán)格按照上述開(kāi)機(jī)順序進(jìn)行。

2每次開(kāi)機(jī)后要預(yù)熱5分鐘，待系統(tǒng)穩(wěn)定后，才可進(jìn)行試驗(yàn)工作。

3如果剛剛開(kāi)機(jī)，需要再開(kāi)機(jī)，至少保證1分鐘的間隔時(shí)間。

4在更換夾具后，首先要注意調(diào)整好可調(diào)擋圈（上下限位開(kāi)關(guān)）。

5尤其在用小力值傳感器做試驗(yàn)時(shí)，一定要調(diào)整好可調(diào)擋圈的位置，以免操作失誤而損壞小力值傳感器。不要超過(guò)傳感器的額定量程。

6任何時(shí)候都不能帶電插撥電源線，否則很容易損壞電氣控制部分。

7試驗(yàn)過(guò)程中，不能遠(yuǎn)離試驗(yàn)機(jī)。

8試驗(yàn)過(guò)程中，除停止按鍵和急停開(kāi)關(guān)外，不要按控制盒上的其它按鍵，否則會(huì)影響試驗(yàn)。

9試驗(yàn)結(jié)束后，一定要關(guān)閉所有電源。

10本計(jì)算機(jī)是專(zhuān)門(mén)用于試驗(yàn)機(jī)控制和數(shù)據(jù)處理的，請(qǐng)勿在計(jì)算機(jī)內(nèi)安裝其它應(yīng)用軟件，以免試驗(yàn)機(jī)應(yīng)用軟件不能正常運(yùn)行。

11計(jì)算機(jī)要嚴(yán)格按照系統(tǒng)要求一步一步退出，正常關(guān)機(jī)，否則會(huì)損壞部分程序，導(dǎo)致軟件無(wú)法正常使用。

12不要使用來(lái)歷不明或與本機(jī)無(wú)關(guān)的軟盤(pán)在試驗(yàn)機(jī)控制用計(jì)算機(jī)上寫(xiě)盤(pán)或讀盤(pán)，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）特殊測(cè)試項(xiàng)目：
1.彈性系數(shù)即彈性楊氏模量定義：同相位的法向應(yīng)力分量與法向應(yīng)變之比。為測(cè)定材料剛性之系數(shù)，其值越高，材料越強(qiáng)韌。
2.比例限：荷重在一定范圍內(nèi)與伸長(zhǎng)可以維持成正比之關(guān)系，其醉大應(yīng)力即為比極限。
3.彈性限：為材料所能承受而不呈永久變形之醉大應(yīng)力。
4.彈性變形：除去荷重后，材料的變形完全消失。
5.永久變形：除去荷重后，材料仍殘留變形。
6.屈服點(diǎn)：材料拉伸時(shí)，變形增快而應(yīng)力不變，此點(diǎn)即為屈服點(diǎn)。屈服點(diǎn)分為上下屈服點(diǎn)，一般以上屈服點(diǎn)作為屈服點(diǎn)。屈服（yield）：荷重超過(guò)比例限與伸長(zhǎng)不再成正比，荷重會(huì)突降，然后在一段時(shí)間內(nèi)，上下起伏，伸長(zhǎng)發(fā)生較大變化，這種現(xiàn)象叫作屈服。

★ 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)

● Tensile stress ● Tensile strength ● Tensile strength ● elongation at break

● 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.
