Abstract: A simulation study on the steerability of a segmented rubber tracked vehicle on low-bearing-capacity peat terrain is performed by considering the position of the vehicle|s turning pole. A set of mathematical equations in the analytical model is used to predict all the important operating parameters of the vehicle during turning to establish the vehicle|s steerability. Seven road wheels are used on each side of the track in order to avoid the track deflection between two consecutive road wheels. A road wheel diameter of 0.22 m and road wheel spacing of 0.225 m are employed to keep the track on the terrain as a rigid footing. The simulation of vehicle steerability in this study is focused on considering the vehicle|s speed of 10 km/h. The turning pole coincides with the same level of the amount of eccentricity of nominal ground pressure and the resultant turning moment resistance.
