Application of ultrasonic exposure for reducing material adhesion
Authors: Zenkov S A 
Published: December 2019

Abstract
When the moist cohesive soil is excavated, the soil sticking and freezing to the working units of the earth-moving machines take place, which considerably reduces their efficiency. There are four main groups of methods intended for eliminating adhesion of soil to the surface of the working bodies of earth-moving machines. As for the nature and the operating principles of the methods, they can be divided into the preventive methods and the means for cleaning working units of earth-moving machines. PM3-4/18 magnetostriction transducer was used in the experiment as a source of ultrasonic oscillations. Ultrasonic exposure belongs to a group of combined methods of eliminating adhesion. In order to evaluate efficiency of ultrasonic exposure the experiments were carried out on shear bench. Environment temperature range for the experiments was limited from -25 to +15 °C. Ultrasonic exposure allows to reduce soil adhesion to working bodies of earth-moving machines due to thermal and vibrational impact on contact surface.

Review of numerical methods for modeling the interaction of soil environments with the tools of soil tillage machines
Authors: Lysych M N 
Published: December 2019

Abstract
A classification is given of methods for studying the process of interaction of soil environments with the tillage tools of soil-cultivating machines. The methods are divided into two groups: mathematical modeling and experimental research. Mathematical methods for studying soil interactions using numerical modeling methods that allow one to overcome the shortcomings of analytical and empirical approaches are considered in more detail. A classification, existing software, and an analysis of the possibilities of continuous and discrete numerical methods are given. Studies were performed using continual methods are analyzed: finite element method (FEM) and computational fluid dynamics (CFD). Also studies using discrete methods are considered: the discrete element method (DEM) and the smooth particle hydrodynamics (SPH). An analysis of existing studies has shown that the finite element method can be used for cohesive soils, making it possible to obtain both strength characteristics and data on the process of destruction and displacement of the soil massif. The computational hydrodynamics method can be effectively applied only to the study of the power characteristics of overmoistened soils. Attempts to extend this approach to a wider range of soils lead to significant errors. Discrete methods are most versatile and reliable. So the method of discrete elements allows to reliably assess both the power and quality characteristics of the tillage process. For example, the shape of the transverse profile, the degree of loosening (compaction) of the soil, the nature of mixing of the soil layers.

Published: December 2019

Abstract
The hierarchical structure of load-lifting cranes of bridge type is considered as a complex dynamic system, on the basis of which the entire object is represented by six levels of ranks of elements. Based on the proposed hierarchical structure, the design process is represented by phases of closed design work. As a result, the main stages of modeling the process of designing a load-lifting cranes crane of bridge type, on the basis of which the algorithm of design automation is built, are identified. Thus, the use of modern modeling tools will allow to abandon field experiments, take into account the maximum number of measured parameters, that ultimately significantly reduces production expenses, reduce time and labor costs, achieve optimal characteristics.
A method to select the finite element models for the structural analysis of machine tools
Authors: Polyakov A N , Kamenev S V 
Published: December 2019

Abstract
This paper presents a method to select the finite element models for the structural systems of machine tools. The method based on the analysis of modelling results obtained for three different machine tools using the different variants of models. Performed numerical experiments have been shown that the most accurate model is one that involves modelling of feed drives and joints. Increased computational costs, however, may reduce applicability of the model. It was found that the elimination of the feed drives from the numerical model of a machine tool increases the error of modelling (up to 25 %) when static analysis performed. The results of modal and harmonic analysis are more stable to changes introduced to the numerical model of a machine tool, as the error of calculated parameters does not exceed 10 %. Moreover, it was found that the numerical models, which include preloaded joints with stiffness more than 16000 N/μm, are different a little from the models with ideal contact. Thus, it was shown that the use of the machine tool’s numerical model without non-ideal contact and feed drives is more preferable if the acceptable error of modelling does not exceed of 25 %.

Published: December 2019

Abstract
Authors propose a new method of information recording in the form of a relief on the surface of a membrane or film made of the thermo shrinkable polyvinyl chloride. The information is recorded with the help of printing equipment. The printing equipment should undergo partial modification to increase contact time of the film with liquid ink on a printing plate. The ink contains certain ingredients that quickly dissolve the film and reduce local internal compressive stresses in the contact zone. The paper represents the shape and size of the relief elements formed on a membrane made of the thermo shrinkable polyvinyl chloride using screen printing with the ink containing a solvent – tetrahydrofuran.

Analysis of the influence of instrumental and regime factors on the quality of wood grinding
Authors: Sergeevichev A , Kushnerev V , Sergeevichev V , Sokolova V , Onegin V 
Published: December 2019

Abstract
The grinding tool does not have a solid cutting edge, in most cases the front angles for abrasive grains are negative, the grains have rounded vertices and an irregular geometric shape. Grinding should be considered as a process of cutting-scratching the surface layer of wood with a large number of abrasive grains of the grinding tool. The main purpose of the grinding process is to prepare the surface for finishing by eliminating irregularities and defects of the previous processing. The effectiveness of grinding to a greater extent depends on the processing conditions, characteristics and properties of the grinding tool. Theoretical studies and analysis of the derived equations for determining the critical values of the rake angle, cut thickness and cutting speed show that all of the above parameters have a significant effect on the amount of lifting of the processed material by abrasive grain and the intensity of the appearance of contact fractures. An increase in the critical thickness of the slice leads to an increase in the deformation of the surface layers of the processed material, and, consequently, to an increase in the depth and number of contact fractures. The increase in the absolute value of the rake angle leads to the need to increase the critical cutting speed to ensure the conditions of chip formation. In general, an increase in cutting speed always has a positive effect on chip formation conditions and on the quality of the machined surface. An increase in the modulus of the rake angle leads to a deterioration in the conditions of chip formation and surface quality. An increase in the radius of curvature of the cutting edge of the grain leads to an increase in the critical thickness of the slice, which entails an increase in contact deformations and fractures.

Published: December 2019

Abstract
This article discusses the possible types of group management strategies. The rationale for choosing a specific group management strategy is given. This article also provides an algorithm for group movement. Then the phases and results of its simulation will be described. Many models can be built for the same system. These models will differ in the degree of detail and account for certain features and modes of operation of the real object, reflect a certain facet of the essence of the system, focus on the study of a certain property or group of properties of the system. Therefore, it is important to state clearly the purpose of modeling at the initial stage of model construction. It is also taken into account that the model is built to solve a specific research problem. The experience of creating universal models has not justified itself due to the bulkiness of the created models and their unsuitability for practical use. To solve each specific problem, you need to have a model that reflects the most important aspects and connections from the point of view of the study. The importance of a specific task of modeling goals is also dictated by the fact that all subsequent stages of modeling are carried out with a focus on a specific goal of the study.

Abstract
The paper presents an algorithm for non-parametric modeling of the process of cutting dense snow formations with snow plow blade. The following parameters are used as parameters involved in the model: cutting force components, width, cutting angles and installation of snow plow blade, depth of cut and physicomechanical properties of dense snow formations (density from 400 to 500 kg/m3). The initial data for the construction of the model were the results of experiments conducted on a laboratory model of snow plow blade for snow removal equipment. Optimization of the non-parametric regression model was carried out using evolutionary strategies, and the result was improved by local descent methods. The model is necessary to predict the course of the cutting process in a wide range of changes in the parameters in the process of studying and using it on full-scale real snow removal equipment.

Published: December 2019

Abstract
The intensification of the transportation processes of mined minerals is one of the key factors in solving the problems of increasing the productivity and competitiveness of the extractive industries. The processes of transportation of mining minerals are associated with their spatial movement by means of belt conveyors. Existing tools for assessing the weight of mining minerals transported by conveyors are based on the use of strain gauge methods and means of control, which allow weighing of mining rocks with acceptable accuracy at a conveyor belt speed of up to 5 m/sec. For conveyors with a high length (more than 10 km), such speed and weighing speed is unacceptable. Therefore, the development of methods and means of controlling the weight of rock transported by a conveyor at high speed is an urgent task. This paper is devoted to the substantiation of the dynamic method of controlling the weight of cargo transported by a belt conveyor based on an assessment of the dynamics of acceleration and deceleration of the rotor of a driving electric motor in steady–state operating conditions.

Abstract
This work demonstrates that the molding technique for polymer-based flexible microwave electronics with various polymers in order to evaluate acceptable boundaries for conductivity and tan loss. Performance evaluation has been done on the microstrip line and patch antennas with and without material improvements. We have demonstrated that improvements in conductivity after 106 S/m do not give significant benefits. The attenuation in microstrip lines has been reduced from 0.16dB/cm to 0.05dB/cm. However, reduction in the tan loss is able to boost antenna gain from 4.2dBi to 6.5dBi.
