| Abstract | ||
| It is generally accepted that normal pressure beneath a track laying vehicle has great influence on the slip and the tractive effort developed by the vehicle. However, and for simplicity, most of the previous works assume uniform pressure underneath the track. Consequently values of experimental results were quiet different from those of the predicted theoretical values.In this paper, emphasizes have been directed towards proper selection of vehicle configuration which is of almost importance. So, and as a result , different types of normal pressure underneath the track have been analyzed, ranging from constant , to uniform sinusoidal, and then to non uniform values. The magnitudes of drawbar pull for each type of pressure distribution on soft ground were evaluated theoretically with the aid of computer, using (''MATLAB'' package). The aim is to obtain the best value of draw-bar pull among these pressure distributions, thus achieving the optimum design criteria | ||
