Technical description & usage range:
1 this machine adopts computer control, acquisition, analysis and processing of the test data, with stress, strain, displacement of three kinds of closed loop control function, can realize the constant load, constant deformation and stress rate and strain rate control, and can be achieved without the impact of conversion during the test. Draw stress-strain, stress time stress displacement curve, and print the test report; the machine uses the latest control technology, the digital controller, control servo motor drives the reducer, the two high precision screw movement test, test bench can run at 0.001 ~ 500mm/min speed. The use of high precision in measuring the source spoke sensor. Its accuracy is 1%, sensitivity is high, the whole system of 1 grade precision; equipped with mainstream brand commercial computer as the control unit, testing parameters, working state control, data acquisition, processing, display and print the test results; Configure the TEST SMART control system on the measurement control system.
2 control system:
A. this program uses open program ports, can be customized for the user specific test method, fast, convenient, reliable, the default implementation of the national standard GB/T228-2002, GB7314-87 and other test methods.
The full resolution of the B. is the same as the tension, compression test and peak, deformation, etc., and the minimum resolution can be set according to the need of automatic calibration and calibration;
C. at the same time, the time, deformation, time, force deformation and force displacement test curve, can be switched to observation, any zoom, horizontal or vertical movement, real-time high-speed sampling.
D. accurate and perfect data analysis function, the mechanical performance index of the test material is analyzed by means of man-machine interaction, which can automatically calculate the elastic modulus, yield strength, non proportional elongation stress, etc., and can also be used to analyze the process and improve the accuracy of the analysis;
E. data using the database management, automatic test data and curve to the database, to ensure the integrity and unity of the data, user query and management.
F. multiple output statements, statements of powerful editing function, the user can according to their own requirements in a very short time to compile any test report format, built-in report editing function can meet user requirements in all aspects of the report, and the operation is simple, easy to learn easily. At the same time the report output is compatible with Word, Excel and other formats.
G. can be used in the three levels of user rights management, for the use of different levels of test personnel.
H. measurement and control system software can work under the Windows98/2000/XP operating system, set aside the data interface, which can be directly connected to the enterprise (test room) of the integrated information management network.
I. control performance:
Including the constant speed, constant speed, constant velocity, displacement and force, and so on;
Variable structure PID control algorithm to adjust the loading process with the constant speed control, error less than 1%, the pressure control error is less than 0.5%;
To provide professional users "control program editor" software, users can customize the specific control procedures according to the actual needs.
3 applicable standards and data processing:
A. users can be customized to meet the national standards or other standard data processing software;
B. test process can simulate the re analysis of the data and test data
