A Study of the Braking Performance of Heavy Trucks Using the “Static Equilibrium” or “Centre of Gravity Range” Technique

This paper shows a performance analysis of a tractor-semitrailer during the braking process, on a dry road surface, under any operating condition. In order to carry out this analysis, mathematical modelling with the “static equilibrium” or “centre of gravity range” technique application was used. The results obtained were corroborated by experimental data and were very satisfactory.

The related computer program was developed in association with Mercedes-Benz of Brazil. At present, this mathematical modelling and the related computer program are being used by Mercedes-Benz of Brazil for definition of the brake system of their heavy vehicles.
