Three, the main composition:

1) Frame combined cylinder control system, 12 sets of output control, can be set a cylinder action including words or multiple reciprocating test, can be set in pairs of coordinated action in the same direction and reciprocating test.

2) The effective stroke of the cylinder is adjustable, and the cylinder can be combined with any other combination.

3) Test number 0 ~ 999,999 can be set arbitrarily, after reaching the set number of automatic stop, stoppage or power off will automatically retain the test results.

4) There is no damage to the self-dynamic test parts equipped with position sensors, and the test will automatically stop.

5) Computer + force value + displacement sensor to achieve double closed-loop control of force and displacement.

6) The parallel port high-speed communication technology of NI, MATLAB and MTS is used to ensure that all channels can collect data, and the servo motor is directly controlled by the computer to complete the accurate loading of all tests to ensure that the data of all channels can be collected at high speed to control the test force and deformation displacement in real time. The display displays all force waveform, maximum, minimum and offset data in real time.

7) With remote control and monitoring capabilities, the manager can remotely watch the test situation and data on the computer, monitor the test process, and can send all or part of the experimental data to the designated screen according to the need.

8) The use of special control software can achieve multi-channel closed-loop control, complete the test of automatic control, automatic measurement and other functions.

9) The use of computer control, directly on the computer to set the work program (that is, directly on the computer to set the test requirements, such as test force, displacement, test times, etc.) automatically run by the computer control equipment, and can directly display the test force and test times in real time, and automatically alarm various failures. Automatically stops testing and retains test results when detecting specimen damage.

10) The test system has automatic correction ability, when the force value is corrected with standard weights, if there is a deviation system automatically correction, while the same machine correction coefficient and force value can be stored, you can call historical correction data, easy to operate.

11) Test real-time display: computer automatic digital and curve dual display, and display 12 groups of different test interfaces at the same time.

12) The cylinder can be horizontally (up and down) on the beam or column, and its own fixed equipment can adjust the Angle, and the fixed way can choose any force Angle. The space between the cylinder and various samples is adjustable. The loading head and the cylinder body are connected by quick joint, which is easy to replace.

13) Unattended test can be basically realized, the test will be automatically stopped after the test is completed or the specimen is damaged, and there will be sound and light alarm, and the test results will be automatically retained.

14) The system adopts electric and gas control.

Four, the main technical parameters:

Measurement accuracy: force (F) ±5%; Size <1mm, ±0.5mm; ≥1mm, ±1mm; Mass ±1%; Angle ±2°; The position error of loading pad is ±5mm.

Full closed-loop computer control is adopted, and the computer display screen is used as the interface of personnel operation equipment, which is intuitive and convenient.
