Coordinate System
Hardware Overview
The SWIFT coordinate system is transducer-based, with the origin located at the
center of the transducer. Positive loads are defined as applied to the outer ring of
the transducer.
•
Vertical force (Fz) is positive up
•
Lateral force (Fy) is positive out of the vehicle
•
Longitudinal force (Fx) is positive out of the transducer
You can change to the MTS Model 329 Road Simulator convention (lateral load
into the vehicle is always positive) or to any coordinate system by changing the
polarities in the calibration file. For instructions on how to change the coordinate
system polarities, see the chapter, “Setting up the Transducer Interface”.
