 DynaFlexPro/Tire is an optional
add-on package to DynaFlexPro, the Maple package
for modeling and simulating the dynamics of mechanical
multibody systems. A graphical user interface,
DynaFlexPro/ModelBuilder, facilitates the rapid
creation of system models using block diagrams
and drop-down menus. DynaFlexPro combines graph
theory with engineering mechanics in algorithms
that automatically generate the system equations
from the system model. Maple’s powerful computer
algebra technologies are used to create small and
efficient sets of system equations in symbolic
form, which facilitates viewing, physical insight,
and sharing.
With DynaFlexPro/Tire, users can incorporate the
latest pneumatic tire models into simulations of
vehicle systems. Kinematic quantities, such as
slip angle, longitudinal slip, and inclination
angle, are derived as optimized computational sequences.
These are used by various tire force models, including
Fiala, Calspan, and Pacejka’s magic tire
formula, to determine the tire forces and moments.
Optional features allow the user to control how
the tire slip and rolling radius are calculated,
and to include tire transients through differential
equations involving relaxation lengths. By generating
optimized simulation code from the symbolic equations,
real-time simulations of complex vehicle models
are obtained.
