Abstract
It is obvious that the tracked vehicles are superior in trafficability on the off road operation. However, their turning performance has still a considerable problem. The previous proposed concept by Ito et. al., regarding the reduction of turning motion resistance of the tracked vehicle by using circular grouser with the application of a pivot turn by controlling the contact length of the braked track have been considered as the effective ways in order to improve the turning performance of tracked vehicles. This paper discusses about the theoretical model for the estimation of the turning motion resistance for both rectangular and circular grouser track models, and for the evaluation of their ratio as well. Validation of the proposed model reveals that the estimated results were closely coincided to the experimental ones.
