In the field of agricultural machinery, various empirical field tests are performed to measure the tillage force for precision tillage. However, the field test performance is costly and time-consuming, and there are many constraints on weather and field soil conditions; the utilization of simulation studies is required to overcome these shortcomings. As a result, the SPH method and the coupled FEM-SPH method are used in this paper to investigate the mouldboard plough–soil interaction. In this paper, the finite element software LS-DYNA was used to build the SPH model and the FEM-SPH coupling model of soil cutting, as well as to investigate the change in cutting resistance during the soil cutting process. The simulation results are compared with those of the experiments, and the curves of the simulation and experiment are in good agreement, which verifies the reliability of the model. The validated simulation model was used to investigate the effects of the cutting speed, depth of cut, inclination angle, and lifting angle of the mouldboard plough on cutting resistance. The simulation studies show that the SPH model takes 5 h and 2 min to compute, while the FEM-SPH coupled model takes 38 min; obviously, the computational efficiency of the FEM-SPH coupled model is higher. The relative errors between the SPH model and the experiment are 2.17% and 3.65%, respectively. The relative errors between the FEM-SPH coupled model and the experiment are 5.96% and 10.67%, respectively. Obviously, the SPH model has a higher computational accuracy. The average cutting resistances predicted by the SPH model and the FEM-SPH coupled model, respectively, were 349.48 N and 306.25 N; these resistances are useful for precision tillage. The cutting resistance increases with the increase in cutting speed and is quadratic; the cutting resistance increases with the increase in cutting depth and is quadratic; the horizontal cutting resistance and the combined cutting resistance increase with the increase in inclination angle, while the vertical cutting resistance remains essentially constant with the increase in inclination angle; the horizontal cutting resistance and combined cutting resistance increase as the lifting angle increases, while the vertical cutting resistance decreases as the lifting angle increases.

When performing various technological operations in crop production, the working bodies of tillage equipment in contact with the soil wear out under the influence of an abrasive environment. (Research purpose) The research purpose is in theoretical substantiation for a method for quantifying the wear capacity of soils with different abrasive characteristics. (Materials and methods) The article presents the evaluation of the abrasive ability of the soil by the wear of a steel rod vertically immersed in the soil and moving translationally. Authors used the standard rod of steel St0; geometric parameters of the worn rod are diameter d = 25-30 millimeters, height h = 250 millimeters; dynamic characteristics during the test are moving speed V = 3 kilometers per hour, distance of movement L = 100 meters. The worn rod sinks to a certain depth, moves in the soil at a constant speed. A device was used to determine the abrasive characteristics of the soil. (Results and discussion) The numerical characteristic of the wear capacity of the soil was determined as the physical value of the wear of the standard worn rod when moving in the soil as A=Q/L, grams per meter. The lower the value of this ratio, the less abrasive components are in the soil; based on the wear data of a standard rod, it is possible to obtain a characteristic of the wear capacity of various soils. (Conclusions) The proposed method allows us to determine the abrasive and wear characteristics of various types of soils. The results of the study make it possible to install working bodies on tillage machines in accordance with the type and wear capacity of the soil in which they will work, which will reduce the cost of their manufacture and increase the efficiency of the use of equipment.
