Mx Data (Overturning Moment)
SWIFT ® 45 GLP Sensors Analyzing SWIFT Data 65
Channel 4 Mx Data
The following figure shows the relationship between Mx, Fz, and Fy, during a
cornering event. Fz decreases as the vertical force is shifted to the opposite
wheel. Fy, the lateral force, increases to prevent side slip resulting in an increase
in the overturning moment, Mx.
Mx = Fy x Distance Z +
1
Fz x Distance Y
After zeroing the SWIFT sensor with the wheel off the ground, a moment Mx
will still be present, as the following figure shows.
1. Actual polarities depend upon how the polarity for each signal is set in the TI.
