DynaFlexPro/Tire

Product Description:

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.
