Based on mechanism and vehicle theories theoretical analysis is pursued and normal driving conditions are put forward. The relations are analyzed between load distribution and power consumption. Mechanical formula is proposed. Furthermore in this paper the theoretical model of the total power consumption is established, and the relations of the total minimized power consumption with the air-cushion pressure and the fan revolution are discussed. The optimum operation point is put forward. The dynamic digital simulation studies are carried out on the operating procedure of the half-track air-cushion vehicle on soft terrain. Mechanical parameters and soil mechanics characteristics affecting vehicle power consumption and riding performance are analyzed. At the same time according to the model formula, the automation control problem is discussed. It is a theoretical instruction for further automation control.
