Overview

This research demonstrates the calibrated contact parameters in foxtail millet simulations, indicating their impact on seeding machinery design.

Key Points

  • The calibrated contact parameters improved the accuracy of DEM simulations, achieving a simulated repose angle of 22.2°.
  • Key parameters such as the restitution coefficient and friction coefficients were meticulously measured and optimized.
  • A Box–Behnken response surface methodology established a quadratic regression model for best parameter combinations.
  • The study shows the practical applicability of calibrated parameters for foxtail millet seeding machinery design.
