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 serves as the first stepping stone in full vehicle simulation because it is simple enough to be comprehended
completely 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 MotionView and MotionSolve:
