Abstract Modeling of workflows of electromechanical systems with linear electromagnetic motors (LEMM) is an integral tool for their improvement in relation to discrete operations, processes and technologies of the agricultural industry or the processing of agricultural products. At the same time, the use of typical application packages for the construction and analysis of low-cost virtual models seems to be especially convenient and relevant. (The purpose of the study) To evaluate the influence of the characteristics of a hollow (non-magnetic) axial channel in the LEMM magnetic system on the allowable changes in the output indicators of the electromechanical system by virtual simulation. (Materials and Methods) Using the specialized software COMSOL Multiphysics 4.3b (CM) Matlab, Simulink, a model of an armored cylindrical two-gap LEMM with a variable geometry of a hollow (air) axial channel, which determines the characteristics of the motor magnetic system and its output energy indicators, is obtained and analyzed. (Results and discussion) Based on the results of the analysis of the inductance matrices formed by the CM simulation, the field distribution in the LEMM magnetic system is presented and the most stressed, in terms of induction values, sections of the magnetic circuit that contribute to the deterioration of the motor properties are identified. Integral indicators are given that determine the quantitative estimates of the permissible decrease in the output characteristics of a LEMM with an axial channel in a magnetic system. (Conclusions) By comparative analysis of the output static characteristics of the motor, the range of ratios of the annular section of the ferromagnetic - non-magnetic (axial channel) parts of the LEMM cylindrical armature is substantiated, for which an acceptable decrease in the output mechanical parameters of the system is provided.

Abstract In today’s modern times, consumers have changed the idea of shopping. They want a functional product with performance at a low price. On the other hand, the consumer demands a variety of products in the market in terms of dimensions and usability. As the requirements are different, the engineers are challenged with different tasks related to the design of production systems, process design, organization and marketing. In this research, we will present some of the special materials used for knife blades manufactured worldwide. The proper selection of materials and their thickness significantly affects the production price, processing method, corrosion resistance, mass. Special emphasis in the work is devoted to the design of the knife blade for household requirements, model ARIA22, made of EN 1.4028 stainless steel material. It describes the work of the die block, blanking punch, the necessary energy parameters for the realization of the processing process with piercing and punching, as well as the profitability of the production.

Abstract The dynamic stability of an interconnected single-walled carbon nanotube is investigated on the basis of the Euler-beam model and with the employment of the spectral Galerkin method. The tubes under investigation are assumed hinged at its both ends and are embedded in an elastic medium. In order to investigate the effect of the surrounding elastic medium on the dynamic stability of the pipe the Pasternak elastic medium is introduced. The critical velocity is calculated for different stiffness of the elastic medium and different density of the conveyed fluid.

Abstract The paper presents the results of modelling and investigation of the gear cutting process using the power skiving method. The investigations are based on the developed geometrical model of undeformed chips. The approach is based on the original method of forming an integral three-dimensional model on the basis of discrete cross-sections of tool tooth in their successive positions on the cutting path, taking into account the shape and size of the gap previously formed by this tooth. The formulae for calculating the cutting force and the forces acting on the work gear and tool are derived as a function of the angular position of the cutter. The dependence of this force on the angle of tool shaft setting and the angle of inclination of gear teeth is studied. The formulae take into account how the cutting intensity changes due to the peculiarities of the kinematics of power skiving technology and the influence of the actual geometric parameters of the tool on the cutting force. Based on the obtained dependencies, a methodology has been developed for the selection of the axial feed rate and spindle set angle to ensure a compromise between the required productivity and the accuracy of the gear profile.

Abstract The paper focuses on analyzing and designing a mounting system for the modified rear powertrain of the E-up Boost. The initial section delves into the theoretical aspects, specifically examining the differing sources of vibration between internal combustion engines and electric powertrains. Following this, the subsequent section presents an in-depth analysis of the powertrain mounting system using ADAMS View. After the analysis is carried out, a robust mounting system is designed and verified through structural analysis.

Abstract For polymer-abrasive brush tools (PABT) working on CNC machines it is necessary to correct their wear constantly, since it is much higher compared to the wear of metal tools. Based on the dependence of tool wear on machining parameters for various materials, it is necessary to study the influence of the physical and mechanical properties of the material machined. The purpose of the paper is to study the process of finishing the surfaces of parts made of materials of different types with PABT. The analysis of dimensional wear of disc PABTs during the polishing various materials with certain physical and mechanical properties is provided in the article. The polishing was carried out in rational modes that ensure high quality and productivity of surface treatment. The similarity theory and dimensional analysis were used to assess the influence of the properties of the material machined on the intensity of PABT filament wear. To calculate it, dimensionless complexes were established, which take into account the physical and mechanical properties of the machined materials and evaluate their resistance to the penetration of abrasive grains, the ability of the material to absorb mechanical energy in the process of deformation and destruction under the impact of PABT filaments. The developed model was created for the first time. It made it possible to solve the problem of predicting the degree of dimensional wear of the disc PABT when polishing various materials, including difficult-to-machine ones. Prediction of the intensity of PABT filaments wear allows timely correction of the tool position during machining on CNC machines to ensure a constant pressing of the PABT to the surface being machined. The obtained Км material coefficient takes into account the influence of the physical and mechanical properties of the machined material and then estimates the intensity of PABT filaments wear. The KМ material coefficient can also be used to assess the PABT life and calculate the economic efficiency of the parts finishing treatment at the stage of technology development and the selection of polishing tools.

Abstract Technological parameters of the activation process in wastewater treatment plant activation systems are analyzed for basic bioreactor configurations, for the chemostat and for the plug flow, both with the recirculation of concentrated activated sludge. The first type of bioreactors represents conventional aerated tanks, but also loop bioreactors. The second type of bioreactors includes, for example, oxidation ditches. The paper presents an evaluation of the basic technological parameters of the activation process for the two mentioned configurations of bioreactor systems with recirculation of concentrated activated sludge. In addition, a new relation for sludge age evaluation is proposed for an activation system with a plug flow bioreactor. The article also provides examples of connections between the values of the technological parameters of the activation process for the two analyzed types of bioreactor systems.
