Description

In this study, we conducted the numerical analysis of excavation the wheel loader. In particular, we focused on bucket excavating behavior for a sloped gravel mountain and its collapse phenomenon after the excavation. The resistive force theory (RFT) was adopted for evaluating of excavation force, while a cellular automaton method was applied to the collapse behavior of gravel mountain.
