Flexible DEM-Based Analysis of Rice Straw Shear Fracture Mechanisms and Comminution Parameter Optimization for Whole-Feed Combine Harvesters
High-moisture rice straw processed by whole-feed combine harvesters often exhibits high cutting resistance and uneven particle size distribution after comminution. To address these issues, a straw comminution device integrated with the straw outlet of the threshing and cleaning system was developed, and the shear fract...
