“…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.

“…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.

“…By comparison, ADAMS was used to simulate complex device motion behaviors, numerically simulating a system composed of multiple objects with consideration of the mass, inertia, and degrees of freedom ( Wang J. W. et al, 2023 ), and has been proven to be an effective tool for motion analysis of multi body dynamics (MBD). Some researchers ( Yuan and Yu, 2020 ; Kim et al., 2022 ) found that the coupling algorithm of DEM and MBD can be used to simulate and analyze the process of complex device operation, such as the vibration of springs. By utilizing the simulation process of the equipment and the interaction with soil particles, the resistance reduction mechanism of the machine can be qualitatively explained.…”

In plant horticulture, furrow fertilizing is a common method to promote plant nutrient absorption and to effectively avoid fertilizer waste. Considering the high resistance caused by soil compaction in southern orchards, an energy-saving ditching device was proposed. A standard ditching blade with self-excited vibration device was designed, and operated in sandy clay with a tillage depth of 30cm. To conduct self-excited vibration ditching experiments, a simulation model of the interaction between soil and the ditching mechanism was established by coupling the ADAMS and EDEM software. To begin with, the ditching device model was first set up, taking into account its motion and morphological characteristics. Then, the MBD-DEM coupling method was employed to investigate the interaction mechanism and the effect of ditching between the soil particles and the ditching blade. Afterwards, the time-domain and frequency-domain characteristics of vibration signals during the ditching process were analyzed using the fast fourier transform (FFT) method, and the energy distribution characteristics were extracted using power spectral density (PSD). The experimental results revealed that the vibrations ditching device has reciprocating displacement in the Dx direction and torsional displacements in the θy and θz directions during operation, verifying the correctness of the coupling simulation and the effectiveness of vibrations ditching resistance reduction. Also, a load vibrations ditching bench test was conducted, and the results demonstrated that the self-excited vibrations ditching device, compared with common ditching device, achieved a reduction in ditching resistance of up to 12.3%. The reasonable parameters of spring stiffness, spring damping, and spring quality in self-excited vibrations ditching device can achieve a satisfied ditching performance with relatively low torque consumption at an appropriate speed.
