摘 要：Quinoa is an ancient crop that is nutritious,balanced,and suitable for most ***,it has not been known and sought by the public until modern *** recent years,quinoa has been intensively known and widely grown in *** mechanized production machines have also been *** the help of DEM,we design and optimize the quinoa combined seeder,improving seeding efficiency and *** this paper,the basic physical and contact mechanics parameters required for the Hertz-Mindlin(no slip)of quinoa seeds in EDEM software were *** coefficient of rolling friction of quinoa seeds was calibrated on DEM,and which of Long Quinoa 4 is 0.043,and that of Meng Quinoa 4 was ***,we can find that the coefficient of rolling friction strengthens the shape to restrict rolling and weakens the shape to increase *** above research provides simulation parameters for the design and optimization of quinoa seed seeding machinery.
