Maplesoft expands scope of automotive models with tire components

New add-on lets MapleSim users produce more accurate real-time vehicle system models.

January 14, 2010   by DE Staff

Maplesoft announced MapleSim Tire Component Library, an add-on for MapleSim, that extends multi-domain MapleSim vehicle models with high-performance pneumatic tire components. Within MapleSim’s graphical environment, fully parameterized force models can be integrated into existing vehicle dynamics models by dragging the component into a diagram and connecting the component to the vehicle model.


Using MapleSim Tire Component Library, engineers can control how the tire slip and rolling radius are calculated and include tire transients through differential equations involving relaxation lengths. In addition, kinematic quantities—such as slip angle, longitudinal slip, and inclination angle—are derived automatically to determine the tire forces and moments. The library also adds support for industry-standard tire models, including Fiala, Calspan, and Pacejka 2002, as well as user-defined tire models.
