Description:
Master Thesis – Evaluation of DEM simulation software for Wheel Loader applications.
The purpose of the thesis work is to evaluate how detailed DEM (Descrete element Method) particles compares with a simplified representation when simulating full vehicle models.
DEM simulation software can be used as a tool to represent the interaction of particles and their environment. These particles are having interaction with each other and other objects in their environment, this interaction is critical to the result of the simulation and how they correlate to the real world. A simplified representation of these particles reduces the knowledge needed to produce results, but is limited in its ability to accurately represent reality. A more detailed particle have the potential to move the simulation closer to the real world at the expense of more initial work on the model.
This investigation will explore the potential of improving our simulation models by implementing a detailed DEM particle and evaluating the changed behavior compared to a simplified model. A baseline is set with the current simulation model, and then a more detailed DEM software is set up and compared to the baseline in terms of modeling complexity, computational demand, correlation to each other and to real world measurements using full vehicle simulations in Simulink and Adams.
