Coordinate System
SWIFT 10 ATV Sensors
Hardware Overview
25
The coordinate system shown below was originally loaded into the TI settings by
MTS. It uses the right-hand rule.
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. For instructions on how to change the coordinate
system polarities, see the chapter, “Setting up the Transducer Interface”.
