“…Under the influence of cyclic loads, there is a change in the soil structure (Pulido-Moncada et al, 2019) and a shift in soil layers (Huang et al, 2021), which has a more negative impact than deformation and compaction. As a result, the conditions for the development of plant root systems worsen (Nawaz et al, 2013;Batey, 2009), which leads to a decrease in crop productivity and yield (Mueller et al, 2010;Golub et al, 2019). Taking into account global trends, the issue of reducing soil degradation under the influence of running systems is an urgent task.…”

“…The use of such models for determining deformations and compaction of the soil is somewhat limited by the fact that the soil has a heterogeneous structure and the effect of contact loads exceed the elasticity of the soil. A number of analytical models of VTI (Vehicle Terrain Interface) have been developed to determine the indicators of soil deformation and track formation (Carman, 2002;Vahedifard et al, 2016;Golub et al, 2019). The use of analytical models requires a significant amount of experimental data on determining the parameters of the agrotechnological environment.…”

The article defines the influence of structural and operational parameters of a machine-tractor unit on changes in the hardness of freshly plowed soil due to deformation and compaction of the soil by wheeled running systems. An experimental model of the effect of pressure in the pneumatic chamber of the wheel, working width and speed of the unit on changes in soil hardness in the area of operation of running systems is obtained. The obtained mathematical models make it possible to predict changes in soil hardness, which makes it possible to reduce the negative impact on the soil of running systems by optimally completing, configuring and selecting the MTU operating mode.

Biomass gasification has been regarded as a promising technology to utilize bioenergy sustainably. However, further exploitation of biomass gasification still needs to overcome a significant number of technical and technological challenges. The results of an investigation of straw pellet air-steam gasification process effectiveness in downdraft gasifier are presented. The method is based on definition of CoP of a gasification process through composing material and heat balances. A design of a pilot gasifier plant with a downdraft gasifier is presented. An outcome of dry syngas from 1kg of pellets with HHV 14.18 MJ•kg -1 was 2.25 m 3 •kg -1 . The HHV of dry syngas was 11.836 MJ•kg -1 . The calculation errors of balances are: 1.82 % for material and 0.83 % for heat. It was found that use of an air-steam mixture as blast gases raises CoP of the gasification process to 83.4 %, which is more than classical methods of gasification. The analysis of balance made it possible to define harmful heat loses of the proсess. It was revealed that losses into environment 861 kJ•kg -1 (6.04 %), losses with coke-like remainder 861 kJ•kg -1 (6.0 %) and around 1 % in total of losses are with moisture and tar. Directions of improvement of a downdraft gasifier are the design or operational mode optimization. The presented investigations could become a basis for a modern method of defining the effectiveness of the gasification process for stationary and mobile gasifiers as well. Using the obtained results the new laboratory practice for students of engineering courses was prepared and successfully tested.

“…To reduce greenhouse gas emissions, it is necessary to increase the use of renewable energy sources [1,2]. In this case, it is a good idea to use pellets, briquettes, rolls of straw from grain crops, sunflower husks and other plant biomass [3] as a renewable fuel for gasifiers [4,5]. In particular, the use of straw pellets to produce generator gas can provide energy autonomy of agricultural production [6].…”

Analysis of studies of the process of generator gas obtaining from straw allows us to draw a conclusion about the suitability of using straw as a fuel for a gasifier. However, the main obstacle to producing generator gas from straw is the formation of solid agglomerates in the process of producing generator gas. In order to avoid the formation of agglomerates, the researchers went through the creation of complex designs of gasifiers. In addition, it was not possible to completely avoid the formation of agglomerates on the working surfaces of gasifiers, in particular on grates. The article discusses the design of the gasifier, which does not have a grate, and gas is extracted through grooves in the side surface of the recovery zone. The article also presents the results of experimental studies of such a gasifier operation. The influence of the air supply to the gasifier and the height of the recovery zone on the concentration of carbon monoxide in the generator gas was established. It was determined that when the air supply is 3.8 l/s, the optimal height of the recovery zone, at which the maximum output of CO is reached, is 100±2 mm. When the air supply is 8.3 l/s, the optimal height of the recovery zone is 90±2 mm, and when the supply is of 12.8 l/s -70±2 mm. Experimental studies of the operation of the power plant using generator gas obtained from straw were also carried out.
