Simulation of front end loader bucket-soil interaction

Abstract. The design of earthmoving equipment requires reliable estimates of resisting forces from the soil or rock to be manipulated. A series of discrete element simulations with polyhedral particles designed to replicate a series of bucket-soil interaction experiments are presented. The experiments involve manipulation of a pile of gravel, consisting of angular and sub-rounded particles, with a …

Optimization of the Angle of Frog in Mouldboard Tillage

This paper investigated the effect of three independent variables including: tillage speed (ranges of below 2.5 m/s and between 2.5 m/s and 5 m/s), tillage depth (range of 10 cm from 0 cm to 30 cm) and frog angle (30° 40°, and 50°) on draught forces. The experimental work was completed with determination of the draught forces using an analytical method (Saunders Equation).
