Simulating Soil–Disc Plough Interaction Using Discrete Element Method–Multi-Body Dynamic Coupling

Due to their (a) lower draught force requirements and (b) ability work at deeper operation depths faster speeds, disc ploughs have gained interest in Australia. A modified version of the plough that involves removing every second fitting larger often more concave discs has become popular. However, development one-way is its infancy, a detailed analysis required, particularly on soil movement. Historically, movement soil–tool interactions conducted using empirical methods. experimental tests are resource labour intensive. When tool interaction can be accurately modelled, efficient tools designed without performing expensive field tests, which may only undertaken certain times year. This study modelled between discrete element method (DEM). As passive-driven tool, rotational speed was DEM-MBD (multi-body dynamic) coupling. The results show coupling predict with maximum relative error 6.9%, good correlation obtained DEM-predicted actual (R2 = 0.68).
