The pneumatic metering device has the advantages of high qualified index, less mechanical
damage to seeds and good adaptability for high-speed operation. But traditional calculation …

Angle of repose is an important macroscopic feature in characterising the interactions within
an assembly of particles. In order to accurately predict the angle of repose of the particle …

Rice bud seeds exhibit different physical properties from other crop seeds as high moisture
content and large length difference of rice buds. Therefore, it is essential to calibrate the …

In order to improve the accuracy of the simulation parameters used in the discrete element
