Office chair leg testing machine 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, the performance is greatly improved.The
speed of arithmetic is much faster,The precision of control is
higher.
