With the MapleSim Tire Component Library, engineers can extend
their high-fidelity, multi-domain MapleSim vehicle models with
high-performance pneumatic tire components. The MapleSim Tire Component
Library provides MapleSim users with industry standard tire force
model components such as Fiala, Calspan, and Pacejka’s magic
tire formula. In addition, linear tire models and user-defined
tire models are available to provide flexibility for investigation
and analysis. With the easy-to-use point-and-click MapleSim graphical
environment, these fully parameterized force models can be integrated
into existing vehicle dynamics models by simply dragging the component
into the diagram and connecting it to the vehicle model.
- Kinematic quantities, such as slip angle, longitudinal slip,
and inclination angle are derived automatically and are available
to the user. These quantities are used by the various tire force
models to determine tire forces and moments.
- Engineers can control
how the tire slip and rolling radius are calculated, and include
tire transients through differential equations involving relaxation
lengths.
- The following industry standard tire models are supported:
Fiala, Calspan, and Pacejka 2002. For custom research and development
applications, user-defined tire models can be easily constructed
using an intuitive interface.
Because the MapleSim Tire Component Library is a fully integrated
add-on package to MapleSim, models incorporating these components
can take full advantage of MapleSim functionality. As a result:
- Dynamic and kinematic quantities, such as normal force and
slip angle, can be plotted and analyzed easily.
- Parameter sets
can be stored and loaded from files to easily test and analyze
different sets of tire properties.
- Realistic tire motion can
be animated by attaching a CAD image to a tire model component.
- High-performance, high-fidelity vehicle dynamics models can
be exported for use in real-time simulations. Models can be exported
to C code using built-in code generation tools, and to Simulink™,
LabVIEW®, and NI VeriStand™ using MapleSim connector
products (available separately).
The MapleSim Tire Component Library will be of interest to the
following users:
- Engineers in the automotive industry requiring real-time
models of vehicle systems
- University teachers and researchers
in vehicle dynamics and stability control
