Numerical analysis on repeating excavation and collapse phenomena of mount gravel by wheel loaders

Abstract

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.
