“…Macroscopically, the shovel and soil model were used as research objects to compare the horizontal plowing resistance and soil force; microscopically, the horizontal and vertical soil particle layers were intercepted, and the arching angle and a velocity trajectory cloud map of the particle layer were investigated. Yeon-Soo Kim developed a comprehensive geotechnical soil-mechanical coupled model based on coupling of the discrete element method (DEM) and multi-body dynamics (MBD) to predict traction forces during plowing,by considering the target tillage depth, which reflects the distribution of soil properties with the change in soil depth, the DEM soil foundation bed was simulated [13]. Regarding soil disturbance, Aili Hasimu and Zhao et al [14][15][16] studied the soil disturbance mainly in terms of the entry earth resistance of the hole-forming device and the transport speed and trajectory of the soil particles.…”

This paper addresses the hole-forming process of a duckbilled hole-forming device. Based on a coupled simulation using the multi-body dynamics software RecurDyn and the discrete element software EDEM, the hole-forming mechanism of a duckbilled hole-forming device and the influence of control parameters on the hole-forming performance of the hole-forming device were studied. In this paper, we analyze the direction and speed of soil particles transported under soil disturbance by a hole-forming device through the simulation and study of the hole-forming mechanism of the hole-forming device. By controlling parameters such as the traction angle, forward speed, and mass of the hole-forming device, the influence of the control parameters on the hole-forming trajectory of the duckbilled hole-forming device was investigated. Orthogonal tests determined the optimal combination of control parameters. The results show that the hole-forming process of the hole-forming device mainly comprises squeezing and shearing the soil to form holes, and the hole-forming performance of the hole-forming device was optimal when the traction angle was 17.3°, the forward speed was 1.11 m/s, and the mass of the hole-forming device was 17.9 kg.

“…Simulating the motion of complex seed-metering device components using EDEM software alone can be challenging, while employing a combined simulation approach using the discrete element method (DEM) and multi-body dynamics (MBD) allows for modeling the effects of complex seed-metering device component motion on particles [18][19][20]. This coupled simulation method has been applied in various agricultural engineering projects; for example: Kim et al [21] developed a full-scale soil-tool-machine coupled model based on DEM and MBD coupling to predict the traction force during tillage according to the tillage depth; Liu et al [22] developed a mathematical model and performed DEM and MBD coupled simulation to investigate the effects of feeding volume and threshing clearance on the load force of the piston rod of the hydraulic cylinder; Zhang et al [23] used MBD-DEM two-way coupling to analyze the harvesting process. Therefore, the coupled simulation method has been proven to be able to fully explain the interactions between the design components and the particles along with the particle motion.…”

In order to solve the problems of poor hole-filling performance and the high seed-breakage rate of conventional rice bud seed precision hole direct seed-metering devices, a side-filled rice precision hole direct seed-metering device was developed, and the mechanism and force analyses for seeding operations were carried out. The key factors affecting seeding quality were determined: rotation speed, seeding angle and seeding height. By coupling the discrete element method (DEM) and multi-rigid body dynamics (MBD), the seed breakage rate and seeding performance at different rotation speeds were analyzed. Single-factor bench testing was used to analyze the effect of a duckbill unit on seeding performance under different factor levels. The three-factor and five-level quadratic regression orthogonal rotation center combination test methods were used to obtain the optimal working parameter combination. The test results showed that when the rotation speed was 47 r/min, the seeding angle was 19°, and the seeding height was 180 mm, the qualified index of seeding was 92.03%, the hole diameter qualified index was 91.62%, and the hole distance variation index was 7.17%. This study provides a reference for the research of mechanical rice sprouting seed-metering devices.

“…Quantification of all forces and moments between tractor and implement when coupled through a three-point linkage is of interest for various purposes, including optimization of implement design, evaluation of tractor settings, or precision farming applications. In [1][2][3], a full-scale soil-implement-machine coupling model based on a combination of DEM (discrete element method) and MBD (multi-body dynamics) was established to predict the traction force as a function of the depth of the tillage during tillage. First, a plowing test was conducted with a field load measurement system to develop a DEM-MBD coupling model to predict traction force according to the depth of the tillage during the calibration and validation of the DEM-MBD coupling model.…”

Efficient use of agricultural tractors is largely determined by the operating modes of its power units. Taking into account the variable nature of external loads, it is necessary to provide structural devices in the tractor, which smooth out changes in hook load, thus reducing the negative impact of external conditions on the operation of its power plant. The present paper is devoted to the design of a tractor attachment with variable characteristics. The methods of studying the variable traction force are analyzed on the output parameters of the technological process, as well as on the power and economic indicators of the power unit. Force analysis of the proposed attachment device is carried out and formulas are obtained to determine the forces and moments at the characteristic points of the device. The paper is of interest to engineers and technicians involved in the creation of promising design schemes for tractor tractors of various operational purposes.
