Analysis of Inter-particle Contact Parameters of Garlic Cloves Using Discrete Element Method

Abstract Purpose The discrete element method (DEM) can be used in agricultural fields such as crop sowing, harvesting, and transportation. Nevertheless, modeling complex crops appropriately shaped particles remains challenging. of the calibration input parameters are important for simulating realistic behaviors using DEM. Methods In this study, particle models representing morphological characteristics size deviations garlic cloves were proposed. Additionally, coefficients friction analyzed contact based on heap formation experiments simultations swing-arm 150 cloves. Results simulation results that residual number particles, a bulk property measured simply experiment, is related to friction. with low counts, properties more clearly differentiated by than angle repose. Moreover, similar actual could not expressed spherical model. Thus, an equation predicting was derived non-spherical clove Five sets presented prediction equation, all close repose garlic. Conclusions Although sizes have wide distribution, appropriate inter-particle predicted. Therefore, process DEM shortened proposed particles.
