materials with large sample deformation and fast test speed. It is suitable for
quality supervision, teaching and scientific research, aerospace, iron and steel
metallurgy, automobile, construction materials and other experimental fields.
Standards
It meets the requirements of GB/T
228.1-2010 <<Tensile
test method for metallic materials at room temperature>> and

as well as
ISO 7500-1,
ASTM E4, EN10002-2, BS 1610, DIN 51221, ISO6892,
etc. It conforms to the requirement of
data
processing of GB, ISO, ASTM, DIN and other standards.
Main machine structure
The main
machine
adopts double space portal structure, with upper space stretching, lower space
compressing and bending. The crossbeam is stepless lifting. The transmission
part adopts arc synchronous toothed belt, and the lead screw pair drives, with

connect with intranet or Internet.
Description of main functions and features of the software
The software is used for testing various metals and nonmetals (e.g. wood-based
panel) by microcomputer controlled electronic universal testing machine. It can
complete real-time measurement and display, real-time control and data
processing, result output and other functions according to the corresponding
standards.

Sub
authority management, different levels of operators have different operation
authority, the menu can be operated is also different, not only the ordinary
operator operation is simple, convenient, fast, but also effectively protect
the system.

deformation and other signals.
Real-time
acquisition and control under
Windows platforms
such as Win
XP, Win 7 & Win 10, etc.
Accurate
timing and high-speed sampling are realized.
-
The
real-time screen display of load deformation, load displacement and other
test curves is realized, and the observation can be switched at any time.
-
The
computer storage, setting, loading and other functions of test parameters,
zero setting, calibration and other operations are carried out from the
software, and each parameter can be conveniently stored and transferred in,
so that a host with multiple sensors can be easily switched, and there is no
number limit.
-
It
supports the constant velocity displacement control mode, and gives the
standard reference curve in the process of debugging parameters by advanced
operators, so that users can actually observe the influence of various
parameters on the effect.
-
Human
computer interaction was used to analyze the data. The processing method can
meet the requirements of GB/T 228-2010 metallic materials tensile test at
room temperature, which is widely used. It can automatically calculate the
elastic modulus, yield strength, specified non proportional elongation
strength and other performance parameters. It can also manually intervene in
the analysis process to improve the accuracy of analysis. It can also
process other data according to the standards provided by users.
-
The
test data is stored in text file to facilitate users' query, and
reprocessing the test data by using any general commercial report and word
processing software. At the same time, it is convenient to transfer data on
the Internet.
-
It can
record and save the data curve of the whole process of the test, and has the
demonstration function to realize the reappearance of the test curve. It can
also be used for curve superposition and comparison, which is convenient for
comparative analysis.
-
The
test report can be printed in the format required by users. Users can choose
the basic information of report output and the content of test results and
curves to meet various needs.
