In order to improve the performance of tracked vehicle, dimensions of grouser shoe of tracked vehicle were analyzed for its optimum tractive performance in this study. To investigate the effects of the grouser thickness ratio and the grouser height on the tractive performance, thrust, rolling resistance and traction generated by the grouser shoe were analyzed by using threedimensional model of soil shearing by changing in grouser thickness ratio and grouser height. According to the results of the theoretical and computer simulation analysis on the grouser shoe dimensions and tractive performance, it was concluded that maximum traction could be obtained when the grouser thickness ratio was 0.1 and the grouser height was 6.5cm for the given soil. It is clear that there were remarkable effects of grouser thickness and grouser height on tractive performance of the tracked vehicle.
