Abstract: This paper presents a method of simplifying the calculations required when Dugoff|s tyre friction model is used for simulation purposes. It also provides a physical interpretation in that it brings to light an idea similar to the traditional friction circle concept implicit in Dugoff|s model. The procedure for calculating the tyre forces is presented, together with a flow chart for use in preparing a suitable computer model.

Keywords: Dugoff|s model; friction circle concept; tyres; tyre force calculation; vehicle dynamics; modelling.
