Abstract:This study is aimed to solve the parameter shortage during discrete element method (DEM) simulation in mechanized deseeding of fresh Rhizoma polygonati, and to calibrate DEM simulation parameters of fresh R. polygonati using physical measurement and simulation trials. First, the physical properties of fresh R. polygonati from picking to 15 days of stacking, and the contact parameters between fresh R. polygonati and different materials along with the prolonging of stacking days were measured through physical ex… Show more
