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 “Setting up the Transducer Interface” in the SWIFT 50
GLP Sensor Product Information manual (MTS part number 100-162-722).
