Abstract: This paper deals with a bond graph (BG) model of road truck, which includes roll and pitch motions. The vehicle system comprises cab, cargo, base frame, suspension system and pneumatic tyres. The dynamic behaviour of the truck has also been presented, which incorporates the wheel/tyres, axle/suspension and frame of the vehicle. The potential usefulness of the integrated BG model of vehicle may be used for the evaluation of the ride comfort. Another focus of the paper is the dynamic and thermal analysis of tyre system, which demonstrates its behaviour at different temperature conditions. The simulation of the model is carried out to obtain the vertical accelerations of the cab, cargo and base frame at various operating speeds. The ride comfort of the cab is evaluated using the FFT analysis at various speeds and the analysis is corroborated with the standard ISO 2631.

Keywords: over the road truck; comfort evaluation; bond graph modelling; ride comfort.
