“…In this study, the DEM was employed to optimize the bucket size of the metering device of the garlic planter. To accurately represent the actual shape of garlic cloves in the analysis model, a 3D mesh model was created using the 3D CAD model for each of the three garlic size groups, which was previously developed by Im et al [8]. Subsequently, the discrete element model parameters were determined through bulk density measurement, sliding test, and repose angle test.…”

“…In this investigation, as the target garlic, we used garlic from the cold Uiseong region, identical to the sample used by Im et al [8], and produced a 3D mesh model of garlic cloves using the 3D CAD model proposed in that study. Figure 3 displays samples of the actual garlic cloves of each group alongside the corresponding 3D CAD and mesh models for contact force calculation.…”

“…In addressing the limitations of the experimental method, studies have been conducted using simulations to predict the performance of garlic planters. Im et al [8] classified garlic samples into four groups based on size and developed a 3D computer-aided design (CAD) model using statistical results on garlic clove shape. The optimal bucket size of the metering device was then determined using the developed CAD model and multi-body dynamics model according to the size of the garlic cloves.…”

“…However, studies that utilized experimental approaches have limitations in design variables or operating conditions and are applicable only within specific sample ranges [3,[5][6][7]. Previous studies that used simulation models executed optimal designs without design variable constraints; however, in some cases, the analysis model was not validated [8], and the actual shape of garlic cloves was not considered in the analysis model, constraining its reliability [10,11].…”

“…Furthermore, we conducted a metering simulation to validate the optimization results and validated the reliability of the optimization technique by comparing the outcomes with the actual test results. To incorporate the actual shape of garlic cloves, we adopted the statistical data proposed by Im et al [8] into the discrete element model. We performed angle of repose and sliding tests to identify the mechanical parameters of the analysis model.…”

In this study, the discrete element method was used to optimize the bucket size for the metering device in a garlic planter for enhancing the productivity of garlic farming according to the garlic size. Statistical information concerning the actual shape of garlic cloves was incorporated, and the mechanical properties of garlic were determined using the bulk density, sliding test, and repose angle test for enhancing the fidelity of the simulation model. The optimal bucket size achieving the target plant rate of 97.5% was determined using the developed discrete element model for the three garlic size groups. The linear search method was used for optimization, and batch simulation was performed to validate the optimized results and confirm the performance index of the metering device. A Gaussian distribution based on statistical information accounted for the various garlic sizes in each group. Finally, a metering test verified the reliability of the optimization technique. The differences between the simulation and test results were within 10% for all performance indices, including missing plant rate, multi-plant rate, and planting rate, indicating the high reliability of the analysis model. Subsequently, the larger garlic groups (Groups 2 and 3) exhibited metering performance close to the target plant rate.

Removal of agricultural pipes used in crop support and greenhouse agriculture is manpower-intensive. However, most agricultural workers are elderly. Therefore, auxiliary devices should be used to allow pipe removal with as little force as possible. In this study, the design parameters of an extraction device were optimized within constraints to minimize the force required to remove agricultural pipes. The optimization parameters are the length of each link and the initial link angle of the device. The driving force, according to the design parameters, was calculated by applying the theory of kinematics. An optimal design plan was derived using an optimization algorithm to minimize the force driving the device within the desired constraint. As a result of the optimization, it was confirmed that the force required to remove the pipe was reduced by 87.1% compared with the initial design value and was designed to suit the user’s convenience.
