Study of vehicle dynamics response to collision in windrows of mine access roads through computer simulation

Abstract

The study presents an ore transport vehicle in simulated collision against the protection windrow (berm), located on the side of the roads, in order to prevent the vehicle from escaping in transit on the road. The work presents a study developed through computer simulation to validate the safety of access roads to mines owned by MRN. The objective is to dimension a windrow that it guarantees the safety of employees who travel with heavy-duty vehicles within the mine's operating fields. The computational simulations were carried out using the software EDEM and motion view to simulate granular particles through the discrete element method (DEM) methodology and the theory of vehicle dynamics respectively. The information for the elaboration of the works was provided by MRN and complemented through scientific studies developed by the Naves Engenharia team. The results presented satisfactory data to the conditions required initially.
