Calibration Strategy to Determine the Interaction Properties of Fertilizer Particles Using Two Laboratory Tests and DEM

Investigating the interactions of granular fertilizers with various types equipment is an essential part agricultural research. A numerical technique simulating mechanical behavior assemblies has advantage data trackings, such as trajectories, velocities, and transient forces particles at any stage test. The interaction parameters were calibrated to simulate responses in EDEM, a discrete element method (DEM) software. Without proper calibration between materials, simulations may not represent real fertilizers. Therefore, this study, strategy presented identify select set DEM input using central composite design (CCD) establish nonlinear relationship dynamic macroscopic fertilizer properties parameters. determined can be used EDEM.
