This paper describes the applications of a computer aided method known as RTVPM to the selection and optimization of the basic design parameters of track systems with rigid links, commonly in use in agricultural and industrial vehicles. It is found that the ratio of roadwheel spacing to track pitch is a significant parameter that affects the tractive performance, particularly on soft terrain. For a given track system configuration and roadwheel spacing, it is important to select an appropriate track pitch to ensure good tractive performance on the one hand and minimal vehicle speed fluctuation on the other. It is also shown that the initial track tension has a considerable effect on tractive performance when the ratio of roadwheel spacing to track pitch is high and that its effect decreases with the decrease of the roadwheel spacing to track pitch ratio. The effect on tractive performance of the ratio of roadwheel spacing to track pitch becomes less significant with the increase of soil strength. It is demonstrated that by selecting the appropriate ratio of roadwheel spacing to track pitch, initial track tension, location of the centre of gravity and other design parameters, an optimum track system configuration for a given operating environment can be evolved.
