PhD student »Parameter identification for soil-tool interaction simulation«
The area "Mathematics for Vehicle Development" works on modeling and simulation methods for the virtual product development of vehicles. One focus is the simulation of the interaction of construction and agricultural machinery with soil and material. We develop, implement and qualify new modeling and simulation methods and apply them in projects with leading industry partners. In this context, we model and simulate soft soils based on the Discrete Element Method (DEM). In order to predict correct reaction forces with this method, it is essential to parametrize the simulation model accordingly. The parameterization step includes a calibration based on real measurements from soil mechanics laboratory tests such as so-called triaxial or adhesion tests.

What you will do
The focus of this PhD project is the development, implementation and validation of an adequate automated parameterization algorithm for DEM-based soil simulation and soil-tool interaction.
For this purpose, different soil mechanics laboratory tests will be investigated and analyzed with respect to their suitability for the parameterization of the soil-tool interaction, also for different physical contact laws. Based on this, different nonlinear optimization approaches will be implemented and analyzed with respect to accuracy, stability and performance. Thereby, the appropriate and problem-related choice of the optimization objective is a crucial aspect of the optimization procedure.
