Destructive Fatigue Furniture Testing Machines for Chair Vertical
Pressure
1. Introduction :
Sofa Seat , Arm and Back Testing Machine is to simulate normal
functional use to determine the strength of the sofa structure by
applying to various parts with loads or forces . Using certain
shape and load modules , with specific form , frequency ,
respectively , repeating load seat , back and armrest . Each point
have force sensor to show the pressure .

3. Main Parameters :
The machine consists form several parts
- Tension mechanism , servo motor and the strap pulley architecture ,
the intensity of the rotation transformed into tension and
supplemented force values turn sensor read correctly tension ,
the action of the closed-loop control of servo motor to achieve a
number of pull . Static and cyclic testing . Rally and speed can be
set free . Mainly used for 5 , 6 , 13 , 14 , 15 , and 16 test .
- In addition to this machine is also configured with two groups of
electric actuator , respectively , for a group of the vertical
apparatus and the horizontal apparatus 1 group , each group
independently adjust the speed and thrust . Stroke is 500mm
- The vertical means of the servo motor can be used for the actuator
, the vertical position adjustment , mainly used for the first 11 .
4 , 22 , 23 and 24 of the test ; the maximum pressure is 150 kg .
- Level device servo motor caused the brake position adjustment of
the pieces up and down and left and right mobile and flexible to
meet the demand for different test location , is mainly used for 10
, 12 . 3 and 12 . 4 testing . 50 kg maximum thrust , adjustable up
and down the range from 500 mm to 1200 mm.
- the bottom plate of the test machine drilling multiple rows of
screw holes for easy installation of different
Attachments and fixed test conditions
- each electric actuator front-end with a quick connector for easy
replacement of the load block and fixture
- control mode : PLC with LCD touch screen
- the maximum tension value:150kg
- the maximum thrust value(horizontal):50kg
- the maximum pressure value(Vertical)150kg
- Can be equipped with computers , recording force and displacement
changes .
