Résumé :
|
The dynamics of several off road vehicles have been investigated using IBM's Continuous Systems Modelling Package with a view to improving the vehicles performance. Three different vehicles have been investigated : a 25 tonne articulated dump truck manufactured by DJB Engineering Ltd., a Vickers Mk 3b/3 battle tank and a small hovercraft designed for agricultural use. The modelling of the vehicle components incorporated many of the non linearities which are present in vehicle suspensions both by chance and by design such as friction and hydro-elastic suspension characteristics. The predictions of the models were then compared to actual measurements which could be made on prototype vehicles.
