Soil Deformation by a Track

Analysis of Tractive Performance of Track-laying Tractors

Abstract

Analyzing photographs of a soil deformation by a model track which was forced to slip, following results were found.
1) Soil was sheared by the track in an upper layer.
2) Soil displacement was proportional to a distance from a leading edge and a slippage.
3) Shear pattern was a plane at the depth of grousers in the case of no space track.
4) In the case of spaced tracks, shear patterns were able to hypothesize to consist of such a logarithmic spiral plane and a plane as the cast of a model shoe.
