Characteristics of dynamics of tracked vehicles steering on ramp

Based on the ground's vertical linear pressure, and by the theories and methods of vector analysis in mathematics and mechanics, the calculation formulas of relationship among instantaneous steering center, resistance moment, tractive force needed, consumed power and the position of vehicle's gravity, steering radius, moving velocity, moving acceleration, vehicle's orientation on ramp, when the vehicle being on ramp were derived. Based on these, the corresponding procedures were compiled and an actual analysis on an actual tracked vehicle was made. Then, the curves of the relationships among these parameters were made, the rules were analysed and the contrast with the steering on horizontal road surface was made. The reference for distributing the moment and power between two driving sprocket wheel of the tracked vehicle is provided.
