The areas of construction machinery and conveyor technology generally combine the problem of the interaction between goods and machines. The term “good” generally stands for the granular media that are moved by the construction machine during the actual work process or during regular transport on continuously operating continuous conveyors. The interaction of machine and goods defines the work and transport process.
The particle mechanical processes are usually represented by the Discrete Element Method (DEM), the idealized good parameters of which have to be determined by complex calibration procedures. Calibration is a procedure for inverse parameter value determination, in which experimental investigations are compared with the results of simulation series with varying parameters. So far, the focus of scientific considerations has primarily been the mapping of realistic flow behavior of the granular substances, which is not sufficient for realistic prospective load analyzes.
The aim of the research project was to develop a method for the automated parameterization of DEM models, which can be used to calculate the dynamic working and movement resistances on components of mobile construction machines and conveyors. This is the key to realistically determining process loads and resistance to movement. This enables a simulation-based prospective analysis of such machines.
