Abstract

Abstract:

A mathematics model of automobiles braked on a rough road surface is established.The nonlinear and time varying footprint tyre model braked crossing the rough road surfaces is presented.Braking processes of BJ 212 automobile crossing even and uneven road surfaces are simulated.Exemplary results show that the more braking distance of automobile increase, the more braking deceleration decrease if the more rough the road surface is.

Key words: automobile, rough road-surface, brak ing, modelling, simulat ion

CLC Number:

TB122
