Acceleration and Braking Events Example
Analyzing SWIFT Data
Mz: The Mz output noted is corrected to give the aligning moment at the center
of the tire. Minimal Mz moments are generated during these straight line
acceleration and braking events.
Time 6 to 10 seconds: During the relatively steady state acceleration of the
vehicle, note the forces recorded.
Fz: Approximately 100 lb of the weight of the vehicle can be seen transferring
from each front wheel to the rear of the vehicle during steady state acceleration.
Time 10 to 13 seconds: During the braking, many of the acceleration forces and
moments described above are reversed.
