Since computing tire forces and moments during a vehicle simulation is one of the most costly tasks, multi-threaded execution
of tire models on a multi-core computer can substantially reduce the clock time for a simulation.
CD-Tire (Comfort and Durability Tire model) is a mathematical model of a tire that is built using a combination of physical
tire information and measured test data of the tire.
The FIALA tire model provides a stepping stone in full vehicle simulation because it is simple enough to be completely
understandable by the MBD analyst. Furthermore, the forces, and torques produced by the tire/road interaction use a series
of physically meaningful parameters.
User Written Tire models are implemented as user subroutines that compute the tire forces and moments, and the user road
model is implemented as a subroutine that computes the road height at a given point.
RMOD-K tire is a series of mathematical tire and road models designed for predicting
vehicle tire response and tire contribution to the overall vehicle response for a wide variety
of operating conditions.
The following topics describe the implementation of RMOD-K tire in
