Optimization of Rotary Blade Wear and Tillage Resistance Based on DEM-MBD Coupling Model

Optimization of Rotary Blade Wear and Tillage Resistance Based on DEM-MBD Coupling Model

To solve the problems of high tillage resistance and the rapid wear of the rotary blade during tillage, this study employed a coupled algorithm of the discrete element method (DEM) and multi-body dynamics (MBD) with Hertz–Mindlin with JKR particle contact theory to establish a rotary blade–sandy soi...
