High Resolution Chair Legs Pressure-resistant Tester , Servo Motor
Control
Chair Legs Pressure-resistant Tester is used to test the Office Chair supports five claws,by loading
vertical pressure to test compressive strength of five claws.
The motor which is used as power source is controlled by
computer.Driving the precision screw rod and dragging the bar to
make pressure down.
Purpose of test:test compressive strength of the Office Chair
claws.Control the quality of products.Find out the defect
position.Provide a reference for improvement.
Program of test:Load to 11120N slowly,keep one minute.unload;Then
load to 11120N slowly again,keep one minute,record the process of
test.
Assessment of results:controlled by a servo motor which can
maintain constant pressure when chair legs are in plastic
deformation status.
Breakpoint,autostop,automatic operation by computer.Customers can
write test program by themselves;The computer generates force -
time and force - shift curve automatically.
Main controller adopts most advanced 32 bit ARM processor in the
21st century.Processing speed has already reached the level of
Pentium general computer.Compared with the traditional 8-bit SCM
measure-control system, theperformance is greatly improved.The
speed of arithmetic is much faster,The precision of control is
higher.
The core device which is used for collecting data adopts the latest
ultra-high precision 24-bit AD.The rate of sampling can reach 2000
times per second,can capture the process of the force variation in
short-term fluctuation.No step in whole journey.Resolution comes up
to500000 degrees,and uses the original 6 point calibration
technology,improving the accuracy further.
The force measurement accuracy is much higher than 0.5 (the
highest) standards of the state.
Windows standard style.Distinct operating mode,detailed
documentation and tips make it becomes the most simple and easy
software to use in testing machine industry.
Your training efficiency of modulation and software will be
improved significantly.
Using multi-threaded parallel processing technology.Real-time
display force - shift, force - time, shift-time and stress-strain
curve in the testing process.Can switch to the picture of curve
what you want to see, and can check the user setting etc.Cabinet
protection structure, guarantee safety absolutely.The tester stops
automatically when the five claws of chair damaged.Fixed pressure
and time can bet set.
