Coordinate System
Hardware Overview
The coordinate system shown below was originally loaded into the TI settings by
MTS. It uses the right-hand rule.
By default, 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) follows the right-hand rule, consistent with Fz and
Fy described above.
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. The coordinate system can be moved along the y-
axis by changing the y-axis parameter in the calibration file. For instructions on
how to change the coordinate system polarities and offset, see
