Seat tester full backrest
- Requirements
The client required a station to test a seat’s back frame 2-way displacement (depth and height adjustment).
The station also required to measure angular displacement of the seat, as well as linear displacement of its H-Frame.
All tests also required simulating a loaded seat by applying weight to it during the test.
- Solution
LG AUTOMATION designed a standalone station with adjustable parameters to redefine the valid range conditions of the unlocking and seat effort.
Several data acquisition components were proposed, such as inclinometers, accelerometers and load cells.
- Results
The station integrated RACE LAKE load cells as well as POSITAL FRABA inclinometers, while reporting and analyzing their measurements in LabVIEW.
The seat was unlocked by using a FESTO servomotor from the underside of the seat by leveraging THOMSON linear rails and KEYENCE contact displacement sensors (LVDT).
