Abstract:

In the context of off-road vehicle simulations, deformable terrain models mostly fall into three categories simple visualization of an assumed terrain deformation, use of empirical relationships for the deformation, or finitediscrete element approaches for the terrain. A real-time vehicle dynamics simulation with a physics-based tire model brush, beam-based or Finite Element models requires a terrain model that accurately reflects the deformation and response of the soil to all possible inputs of the tire in order to correctly simulate the response of the vehicle. The real-time requirement makes complex finitediscrete element approaches unfeasible, and the use of a ring or beam -based tire model excludes purely empirical terrain models.
