Studies on the Traction Resistance of Wheel on Wet Soil (1)

Abstract

The traction resistance of the single wheel rolling on soil was measured under various conditions. The results obtained are summerized as follows: (1) The resistance and the weight of wheel stand in logarithmic linear relationship.
(2) Within the plastic range of soil, the wheel oflarger width decreases the resistance as much.
(3) The minimum resistance is observed near the plastic limit. (4) The reaction of soils to the applied pressure and the adhesion of soils seems to play an important rôle in the traction resistance.
