Fx Data (Longitudinal Force)
This figure shows the Fx (longitudinal force) data.
•
The offset in Fx after zeroing the SWIFT sensor is due to frictional force
and rolling resistance on a flat road.
•
There is a strong similarity between Fx and Mz, due to the SWIFT sensor
measurement characteristics. That is, the SWIFT sensor measures at the
transducer centerline. As a result, any Fx load results in an additional Mz
output:
Mz due to Fx loading = Fx load x Distance
