Model of steered tyred wheel, three-dimensional problem

The paper presents a tyred wheel model. It describes an interaction between tyre and even as well as uneven road surface, in steady state or transient state. The influence of kingpin axis positioning as well as elastic properties of tyre and steering system is taken into account. The model results from a compromise between the following requirements: accuracy of phenomenon description, limitations of formal clearness, length of the computer program code, calculation time and feasibility of experimental verification of car movement simulation model. This tyred wheel model has been used effectively in simulation of biaxial vehicles movement and dynamics.
