| ABSTRACT Mobility is the ability to move freely and rapidly over the terrain of interest to accomplish varied combat objectives. The vehicle weight and its footprint determine the resultant ground pressure that the vehicle imparts on the soil. The soil strength, coupled with the ground pressure, determines vehicle cone index, VCI, which is the key for vehicle mobility. This paper presented a theoretical evaluation of the vehicle mobility and predicts its performance on deformable soil. For this purpose, soil field test was carried out using cone penetrometer in situ to measure the strength of different soils. The vehicle cone index was calculated using vehicle parameters. A comparison of rating cone index with the vehicle cone index indicates whether the vehicle can negotiate the given soil condition for a given number of passes. | ||
