Abstract
The effect of side cutting angle β of an equilateral trapezoid grouser on the tractive performance of the flexible rubber tracked vehicle was investigated by means of a rigorous simulation program. As a result, it is clarified that the optimum side cutting angle β is π/6rad when the vehicle is moving up a sloped terrain during driving state and turning on a flat terrain and the optimum angle β is 0rad when the vehicle is moving down on a sloped terrain during braking state.
