Analysis of the Resistance to Teeth During the Picking Process Based on DEM-MBD Coupling Simulation

Year: 2025

Type: article

Abstract: To improve the film-picking performance of toothed chain tillage residual film recycling machines, the working parameters of a film-picking device were optimized using a Box–Behnken design, with the film-picking rate as the response parameter. The effectiveness of the film-picking device, along with soil compaction, torque, and stress on the picking teeth during the process, was evaluated through DEM-MBD coupling simulations and experiments. The optimized working parameters for the film-lifting device were found to be forward speed v=1.94 m·s−1, picking tooth speed n=10.47 rad·s−1, and penetration depth h=125 mm. Under these conditions, the film-picking rate for the single-tooth and multi-tooth devices were 88% and 90%, respectively, with a 2% error. The simulation and experimental values for soil compaction, torque, and stress during the film-picking process were 800 Pa, 2.72 N·m, and 6.4 N, respectively. The corresponding simulation values were 870 Pa, 2.53 N·m, and 6.5 N, with errors of 8%, 7%, and 2%. This study provides valuable insights for optimizing the design of residual film recycling machines and predicting soil compaction, tooth torque, and stress.
