Abstract

This paper presents the investigation on the characteristics of bulldozing resistance arising at the sides of track of a revoluting tracked vehicle obtained from the two-dimensional bulldozing resistance experiment with various types of soils and the revolutionary bulldozing experiment using blades.<br>It was revealed that the horizontal bulldozing resistance can be expressed in the function of two variables, the cutting depth and the amount of heaped soil, and the bulldozing resistance moment at the steering center holds a constant without relying on the turning radius. It was also clarified that the bulldozing resistance moment is estimated satisfactorily by use of the horizontal bulldozing resistance formula. Based on the experimental results, a predicting formula for computing the required driving force for the revolution has been proposed.
