A Travelling Performance of Rigid Lugged Wheels (Part 3)

Analysis of Soil Reactions Acting on a Lug Surface and its Comparison with Experiment

Abstract

Based on the slip-line fields proposed in the part 2, a soil reaction acting on a lug surface is elucidated in this part of study by analyzing areas of soil-lug interface. Besides, a soil bin test was performed to obtain an experimental evidence for soil reaction on a lug, in which especially a lug angle and a slippage were changed in several stages. A good approximation of theory to experiment for waves of a horizontal (net thrust) and a vertical (dynamic contact) forces was obtained qualitatively as shown in Fig. 5 to 7, while a more precise analysis is desirable for a quantitative prediction.
