| description | The operating parameters and operating effect of a residual film recycling device can be predicted, and the key parameters can be determined based on the DEM–MBD coupling simulation. The parameters obtained from the parameter calibration are the basis of the simulation. This study calibrates DEM parameters for the soil-touching components of a tillage residual film recycling machine. A film-picking model for elastic tooth–soil–residual film interactions was established. The reliability of the contact parameters was verified by comparing the simulation and experimental angle of repose for soil–soil (43.6° vs. 42.42°, error was 2.7%) and residual film–residual film (43° vs. 43.7°, error was 1.6%) using the funnel and bucket methods. A DEM model for film–soil detachment was developed, with a force analysis showing an 8.1% error between the simulation (0.34 N) and experiment (0.37 N). Additionally, a DEM–MBD coupling model was used to analyze the recovery rate of residual film under elastic teeth, yielding a 2% error between simulation (90%) and experiment (92%). This study provides a basis for DEM parameter optimization in soil-touching components. |
