顧名思義，就是控制試驗機運作的系統，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及各項試驗參數，若該機帶有電腦的話，也可以由電腦實現各項功能并進行數據處理分析、試驗結果打印。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。

開關機注意事項:

1開機時主機和計算機的開機順序會影響計算機的通訊初始化設置，所以務必請用戶嚴格按照上述開機順序進行。

2每次開機后要預熱5分鐘，待系統穩定后，才可進行試驗工作。

3如果剛剛開機，需要再開機，至少保證1分鐘的間隔時間。

4在更換夾具后，首先要注意調整好可調擋圈（上下限位開關）。

5尤其在用小力值傳感器做試驗時，一定要調整好可調擋圈的位置，以免操作失誤而損壞小力值傳感器。不要超過傳感器的額定量程。

6任何時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試驗過程中，不能遠離試驗機。

8試驗過程中，除停止按鍵和急停開關外，不要按控制盒上的其它按鍵，否則會影響試驗。

9試驗結束后，一定要關閉所有電源。

10本計算機是專門用于試驗機控制和數據處理的，請勿在計算機內安裝其它應用軟件，以免試驗機應用軟件不能正常運行。

11計算機要嚴格按照系統要求一步一步退出，正常關機，否則會損壞部分程序，導致軟件無法正常使用。

12不要使用來歷不明或與本機無關的軟盤在試驗機控制用計算機上寫盤或讀盤，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.

測試項目：（普通顯示值及計算值）

★拉伸應力　　★拉伸強度

★扯斷強度　　★扯斷伸長率

★定伸應力　　★定應力伸長率

★定應力力值　★撕裂強度

★任意點力值　★任意點伸長率

●拉伸應力　　　●拉伸強度                 ●扯斷強度　　　●扯斷伸長率
●定伸應力　　　●定應力伸長率           ●定應力力值　　●撕裂強度
●任意點力值　　●任意點伸長率           ●抽出力　　　　●粘合力及取峰值計算值
●壓力試驗　　　●剪切剝離力試驗        ●彎曲試驗　　　●拔出力穿刺力試驗

（二）特殊測試項目：
1.彈性系數即彈性楊氏模量定義：同相位的法向應力分量與法向應變之比。為測定材料剛性之系數，其值越高，材料越強韌。
2.比例限：荷重在一定范圍內與伸長可以維持成正比之關系，其醉大應力即為比極限。
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：材料拉伸時，變形增快而應力不變，此點即為屈服點。屈服點分為上下屈服點，一般以上屈服點作為屈服點。屈服（yield）：荷重超過比例限與伸長不再成正比，荷重會突降，然后在一段時間內，上下起伏，伸長發生較大變化，這種現象叫作屈服。
7.屈服強度：拉伸時，永久伸長率達到某一規定值之荷重，除以平行部原斷面積，所得之商。
8.彈簧K值：與變形同相位的作用力分量與形變之比。
9.有效彈性和滯后損失：在復合材料拉力試驗機上，以一定的速度將試樣拉伸到一定的伸長率或拉伸到規定的負荷時，測定試樣收縮時恢復的功和伸張時消耗的功之比的百分數，即為有效彈性；測定試樣伸長、收縮時所損失的能與伸長時所消耗的功之比的百分數，即為滯后損失。

Test items: (common display value and calculated value)

★ 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.
