“…It should be pointed out that the Lagrange equations were used earlier to study the dynamics of multi-element MTA (Beloev et al, 2015). Application of this method does not allow investigation of the aggregate dynamics, which may change the scheme of aggregation.…”

“…Increased crop production efficiency can be achieved by using combined tillage-sowing aggregates, which can perform two or more technological operations in one field pass. Such aggregates are usually multi-element machines consisting of three elements -a tractor, a seed tank and a sowing machine -moving in succession one after the other (Beloev et al, 2015;Ivanovs et al, 2018). The most frequent layout schemes of such aggregates are: 1 tractortank for seed material -sowing machine; 2 tractor -sowing machine -tank.…”

The paper presents a dynamic model of four-element machine-and-tractor designed on the basis of a combined soil-cultivating-sowing aggregate and a tractor with an articulated frame. The pseudo velocity of the first tractor half-frame was considered a generalised coordinate. The control impact upon the tractor was obtained by means of the bending angle of the tractor half-frames. The trajectories and movement speeds of the aggregate elements were calculated as a function of time for the driving mode along a straight-line path and the tractor movement according to the harmonic control law. By means of the measuring system, trajectories of the aggregate elements were obtained. It was established that the movement trajectories of the aggregate elements represent a complex assessment parameter of the mathematical model adequacy of the aggregate plane-parallel movement. There was found a regularity of the aggregate turning radius and the bending angle of the tractor half-frames.

“…Ballasting of tractors is carried out mainly by installing removable ballast weights in front of the tractor frame on a special bracket and on the disks of the rear wheels, as well as an additional set of front and rear wheels, or only the rear ones. Sometimes on some models (Terrion 5280, Terrion 7360), weights are also installed on the front wheel disks (Cviklovic et al, 2021;Artiomov et al, 2021;Ivanovs et al, 2020;Beloev et al, 2015).…”

When designing and determining the potential technical capabilities and characteristics of the tractor, the so-called traction calculation is carried out. The aim of the work is to study regularities of changes in the traction and coupling characteristics of a tractor with an articulated frame depending on the size of the ballast, the presence of dual wheels and other parameters, using the KhTZ-242K tractor as an example. The numerical solution of the deduced mathematical model made it possible to obtain graphical dependences of the change in the main traction and coupling characteristics of the tractor KhTZ-242K depending on the mass of the tractor, which varied from 8600 kg to 10100 kg by changing the ballast mass. The maximum tractive power of the tractor on single wheels without a ballast is 121 kW, which is achieved at a speed of 12 km∙h–1, and on single wheels with a ballast 122 kW, at a speed of 15 km∙h–1. This, in its turn, greatly affects the productivity and fuel efficiency of the aggregate.

In cassette-type selection seeders, a cassette loading device sequentially conveys cassettes filled with seed material to the planting mechanism of the seeder. (Research purpose) The research aims to calculate the geometric parameters and identify the cassette material in the development of a robotic cassette loading device for the selection seeder. (Materials and methods) The geometric parameters of the cassettes are determined based on the existing cassette loading device of the model SSS-2-6 selection seeder and the selection sowing specifi cations. Fourier transform infrared spectroscopy with the wavenumber range of 400-4000 cm–1 is used to identify a polymer material suitable for manufacturing cassettes and a guide plate for a selection seeder. (Results and discussion) The geometric parameters of cassettes, cells, cassette blocks, and guide plates are determined by using various design solutions employed in previous cassettes for the loading device. The objectives of the study also encompass the selection of polymer material for the manufacture of the cassette using 3D modeling techniques. To accomplish this, it was necessary to identify the specific polymer material of the plastic cassette and guide plate samples currently used in the loading device of the SSSe-6 selection seeder. The qualitative composition of these samples is determined by infrared spectroscopy using a Simex FT-801 Infrared Fourier spectrometer. (Conclusions) The geometric parameters essential for modeling, manufacturing and further development of a robotic cassette loading device are calculated. It has been established that the device is made of a copolymer consisting of acrylonitrile, polybutadiene and styrene (known as ABS plastic), which has a sliding friction coefficient approximately 0.47-0.54. In order to decrease the coefficient of cassette friction when driving along the guide plates, additives like ceramide can be introduced into ABS during their production enhancing its sliding properties.
