What is 63 47 N352 Zhiqi Zheng about?
This study establishes a maize straw cutting model using the discrete element method (DEM) to simulate the straw cutting process and calibrate relevant parameters. The maximum straw cutting resistance was found to be 199 N, with significant parameters identified as normal and shear stiffness between particles and blades. The model demonstrated high accuracy, with a relative error of less than 9.1% between simulation and experimental results, providing insights for improving straw management practices.
