The vehicle during travel is primarily dependent on two forces, namely the bearing capacity of the soil-supporting vehicle and the shear strength of the ground-propelling vehicle's undercarriage. Because the soil on the soft ground has extremely high water content, the soil is soft and heavy, the plasticity and the adhesiveness are high, and the mechanical strength is poor, the adhesion of a walking mechanism on the soil is small, and the walking mechanism is easy to slip and sink. In addition, although the soil has a certain supporting force, the friction between the wheels and the soil is insufficient due to the small shearing resistance of the soil, so that the vehicle cannot obtain enough propelling force and cannot advance.
At present, the serious adhesion of soil to vehicles and the poor trafficability of the vehicles on soft ground are two technical problems in the field of soil-vehicle systems, and many researchers are dedicated to the research on the soil-vehicle systems, so that a large number of theoretical and experimental researches are carried out, and a basis is provided for the design and development of soft ground running mechanisms.
