测试项目：

（一）普通测试项目：（普通显示值及计算值）
●拉伸应力　　　●拉伸强度                 ●扯断强度　　　●扯断伸长率
●定伸应力　　　●定应力伸长率           ●定应力力值　　●撕裂强度

（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。

Precautions for turning on/off the machine:

When starting up, the order in which the host and computer start up will affect the communication initialization settings of the computer, so it is essential for users to strictly follow the above startup order.

After each startup, it is necessary to preheat for 5 minutes and wait for the system to stabilize before conducting the test work.

If it has just started up and needs to be restarted, ensure at least a 1-minute interval.

After replacing the fixture, first pay attention to adjusting the adjustable retaining ring (upper and lower limit switches).

Especially when conducting experiments with small force sensors, it is important to adjust the position of the adjustable retaining ring to avoid damaging the small force sensor due to operational errors. Do not exceed the rated range of the sensor.

At any time, do not plug or unplug the power cord with electricity, otherwise it is easy to damage the electrical control part.

During the testing process, do not stay away from the testing machine.

During the test, do not press any other buttons on the control box except for the stop button and emergency stop switch, as this will affect the test.

After the experiment, all power sources must be turned off.

10 computers are specifically designed for testing machine control and data processing. Please do not install other application software inside the computer to prevent the testing machine application software from running properly.

11. The computer must strictly follow the system requirements to exit step by step and shut down normally, otherwise it may damage some programs and cause the software to not function properly.

Do not use floppy disks of unknown origin or unrelated to the machine to write or read on the computer controlled by the testing machine, in order to avoid virus infection.

Performance characteristics:

The microcomputer controlled electronic tensile testing machine adopts advanced design concepts from abroad, with beautiful appearance, convenient operation, and stable and reliable performance. The computer collects and controls data through the fully digital control system developed by our company, and directly controls the rotation of the fully digital speed control motor through the fully digital speed control controller. The motor speed is reduced by the arc synchronous reduction system and transmitted to the precision ball screw pair to achieve the lifting and lowering of the crossbeam, completing mechanical performance tests such as tensile, peeling, and compression of the specimen.

The professional software of the testing machine can automatically obtain data such as fixed elongation, fixed force elongation, tensile strength, sample elongation, upper and lower yield, and yield strength, and can also meet the requirements of displacement control. The control and data processing of the computer control system for the experimental process comply with the requirements of corresponding national standards for metals, non-metals, and composite materials, and the test reports are diverse, such as WORD, EXECEL, and other methods.

Instrument characteristics

1. Using a high-precision, fully digital speed control system and precision reduction system, the precision screw pair is driven for testing, achieving a wide range of speed adjustment during the testing process with low noise and smooth operation.

2. The universal joint cross pin structure can be selected, which is convenient for sample clamping and ensures the concentricity of the test. On the other hand, it effectively eliminates the influence of irregular samples on the sensor.

3. The Windows operating system has a user-friendly interface, which can display the interface for selecting test methods, selecting test parameters, displaying test operations and results, and displaying curves. It can also display various parameter curves in real time, making it easy to analyze test data and monitor the process. The test results can be output in WORD and EXCEL format, which can directly realize the experimental process。

Attachment:

One one-year warranty certificate and one Chinese operating manual each.

Two sets of testing machine fixtures.

One set of specialized testing software for 3 tensile testing machines.

One set of 4-brand computers and one color printer (optional).

Test items:

（1） Normal test items: (Normal display value and calculated value)

● Tensile stress ● Tensile strength ● Breaking strength ● Elongation at break

● Constant tensile stress ● Constant stress elongation rate ● Constant stress value ● Tear strength

● Force value at any point ● Elongation at any point ● Extraction force ● Adhesive force and peak value calculation

● Pressure test ● Shear peeling force test ● Bending test ● Pulling force puncture force test

（2） Special testing items:

1. The elastic coefficient, also known as the Young's modulus of elasticity, is defined as the ratio of the normal stress component in the same phase to the normal strain. To determine the coefficient of material rigidity, the higher the value, the stronger and tougher the material.

2. Proportional limit: The load can maintain a proportional relationship with elongation within a certain range, and its maximum stress is the proportional limit.

3. Elastic limit: The maximum stress that a 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 still retains deformation.

6. Yield point: When the material is stretched, the deformation increases rapidly while the stress remains constant, and this point is called the yield point. The yield point is divided into upper and lower yield points, and generally the yield point above is used as the yield point. Yield: When the load exceeds the proportional limit and is no longer proportional to elongation, the load will suddenly decrease, and then fluctuate up and down over a period of time, causing significant changes in elongation. This phenomenon is called yield.

7. Yield strength: The quotient obtained by dividing the load at which the permanent elongation reaches a specified value during tension by the original cross-sectional area of the parallel part.

8. Spring K value: The ratio of the force component in the same phase as the deformation to the deformation.

9. Effective elasticity and hysteresis loss: On a composite material tensile testing machine, when the specimen is stretched at a certain speed to a certain elongation or to a specified load, the percentage of work recovered during contraction and consumed during extension is measured, which is the effective elasticity; The percentage of the energy lost during the elongation and contraction of the sample compared to the work consumed during elongation is called the hysteresis loss.

Test steps

1. Tensile test

One is to select the measuring range based on the sample, hang the thallium and align it with the marking line, and adjust the buffer valve to match the range. The second step is to turn on the power, start the oil pump, open the oil delivery valve, and let the piston rise and fall by 200mm, 2-3 times. The third is to raise the piston by 20mm to 40mm and align the pointer with the zero position. The fourth is to adjust and move the crossbeam to the appropriate position. Close the oil delivery valve, press the "open" and "clamp" buttons on the chuck, clamp the sample, and make sure that the sample is in a vertical and middle position. Adjust the speed of the indicator disk according to the required loading speed in the experiment. The fifth step is to open the oil delivery valve and start loading, so that the rotation speed of the pointer is basically consistent with the speed of the tracking plate. After the sample is damaged, close the oil delivery valve, record the test data, set the passive needle back to the zero position, and remove the broken sample. Seven is to repeat the content from two to six and continue with the next experiment.

2. Compression test

One is to select the range based on the test block, hang the thallium and align it with the marking line, and adjust the buffer valve to match the range range. The second is to connect the power supply, start the oil pump, open the oil delivery valve to raise the piston by a certain distance, adjust the pointer to zero, and close the oil delivery valve. The third is to activate the loading speed indicator and adjust the indicator disk to rotate at a certain speed based on the loading speed. The fourth is to place the test blocks properly. The fifth is to quickly adjust the oil supply valve to the corresponding position, keeping the pointer and indicator plate rotating synchronously until the test block is crushed. Close the oil supply valve and open the return valve. Six is to record the experimental data and retract the driven needle. Seven is to remove the crushed test block. Repeat the content from four to eight until all test blocks are completed.
