Published: January 2022

This article describes and reflects upon a student art project assignment and accompanying issue-advocacy written piece that allows students to explore topics of social justice and environmental sustainability in a business and society senior seminar course. The process of producing art and creative writing allows students to critically reflect on current business ethics concepts that are relevant to their interests. The art is displayed in a gallery exhibit, allowing for further intellectual exploration as students explain their work to others. The learning outcomes of this art project are two-fold. First, students and faculty develop a greater sense of liberatory consciousness, a social identity-shaping mechanism that extends beyond disciplinary boundaries. Importantly, as faculty, we learn a great deal from our students, particularly during the art exhibit. Second, students develop competency in, and a passion for, issue advocacy about important social and environmental issues. Ultimately, this assignment inspires students to become future leaders in professional organizations that are ethical, inclusive, and environmentally sustainable.

Published: January 2022

This article describes the purpose and applications of the starter generator set. The modes of operation of a starter-generator set are considered both as a sequential excitation direct current electric motor, which rotates the shaft of an internal combustion engine, and as a generator, when an electric machine operates as a direct current source of independent excitation, supplying power to electric control circuits, electric motors of auxiliary electrical equipment, lighting and battery charging. Additional functions of a starter-generator set in the form of a start-stop system, regenerative braking, booster acceleration of a vehicle, damping of torsional moments of the shaft of an internal combustion engine and control of energy flows in the on-board network were studied.
The choice and substantiation of the optimal scheme, as well as the design of the starter-generator device, were carried out. The main technical and economic parameters of the starter-generator set were determined. The design of a starter-generator set was presented. This design is a reversible electric machine. A block diagram of a starter-generator set was developed.
Electrical machines used for starter-generator sets are considered. The design of an asynchronous machine with a squirrel-cage rotor, a synchronous machine with electromagnetic excitation, a valve machine with permanent magnets, a contactless machine, a synchronous machine with permanent magnets, and a valve machine with self-excitation are described. A review and analysis of electrical machines used in starter-generator sets of leading foreign companies is carried out.
The design of a reversible induction-dynamic machine is considered. The rotor rotates outside, and not inside the motor and is a short-circuited winding with a cast aluminum cage. The calculation of the main parameters of a reversible induction-dynamic machine was carried out both in the starting and in the generator modes. The calculation using a method similar to that of an induction motor was carried out.
Development of a complex of mathematical models of a vehicle suspension for fatigue life analysis
Authors: Kulagin V. A. 
Published: January 2022

The reduction in the duration of the development of new vehicles and the associated desire to reduce the costs of automotive plants contribute to a more active application of mathematical modeling to solve engineering problems. The tasks, which are analyzing and predicting the fatigue life of vehicle components and assemblies, can be solved using a set of methods and tools of mathematical modeling.
This article discusses the development of a complex of mathematical models of the front and rear suspensions of a passenger automobile, which have the properties necessary for accurate reproduction of wheel loads and dynamic behavior of the suspension as a mechanical system. The complex of mathematical models is implemented in a multi-link modeling environment. The models are designed to carry out a subsequent validation study of the loading of individual suspension components during forced service life tests. In the future, this complex of mathematical models can be used for simulation of semi-natural forced resource tests of the suspension module, as well as a sample for the development of suspension models of other automobiles.
The purpose of this work is to form sufficient requirements for mathematical models for the implementation of fatigue durability studies using mathematical modeling methods and obtaining reliable calculation results. Research engineers will be able to follow these requirements to determine and collect initial data for the development of their own mathematical models.
Results of experimental studies of an agricultural tractor with an elastic-damping mechanism in a power train
Authors: Sen'kevich S. E. 
Published: January 2022

Improving the operational efficiency of agricultural tractors is one of the main factors that helps to increase productivity while significantly reducing energy costs. The developments that are associated with improving the design of power transmissions for wheeled agricultural tractors are very important, because its indispensable condition is to increase labor productivity in agricultural production. Achievement of the required characteristics of agricultural tractors is determined by the properties of the power train and the interaction of associated systems. One of the main qualities of a power train should be the ability to absorb torsional vibrations and damp the load.
The article presents studies of the constructive improvement of the power transmission of an agricultural tractor by installing a developed elastic-damping mechanism using the example of a tractor of a small traction class. Considering the relevance of the topic, the article solved the problem of determining the influence of the elastic-damping mechanism installed in the power transmission of the tractor on its operation with the cultivator.
The paper analyzed the cross-correlation function and the mutual spectral density of two processes: the angular speed of rotation of the crankshaft of the engine and the angular speed of rotation of the drive wheel, which showed a change in the speed of propagation of passing frequencies of load oscillations along the shafting and displacement of the frequency of disturbing influences.
Analytical determination of static and dynamic elastic characteristics of pneumohydraulic suspension systems
Authors: Tsipilev A. A. , Nakaznoy O. A. 
Published: January 2022

When developing new suspensions for tracked and wheeled vehicles, as well as in the so-called reverse engineering of existing structures (including in the educational process of training personnel), it is necessary to solve the problem of finding the elastic characteristics of the suspension. In the first case, it is necessary to ensure the fulfillment of the specified tactical and technical requirements, in the second - to restore the form of characteristics according to a known design. Both of these tasks are greatly complicated in the absence of precise and universal analytical dependencies suitable for determining the characteristics of elastic suspension elements of various design implementations. The experience of interaction with some factories shows that designers, not being able to qualitatively calculate the elastic characteristics, use the method of selection and analogy, when for a new vehicle they use the suspension as on the old one, scaling it in size in order to approximately keep the values of working pressures. The numerous bench tests are carried out, which results are used for selecting required charging volume and pressure. Suspensions with backpressure cause particular difficulty, since not only the final characteristic, but also the performance of the entire unit depends on the combination of volumes and pressures of the two chambers, which work in antiphase: when one is loaded, the other is unloaded, and vice versa. Using analytical dependencies will reduce the time spent on design, to parameterize, to a certain extent, the suspension kinematics, to obtain the values of the equivalent suspension stiffness, and also to be able to develop the characteristics of the model range of pneumohydraulic springs for vehicles of various weight categories.
This article presents a technique for the analytical determination of the characteristics of pneumohydraulic springs of various designs. The options include both actually used in modern and historical technology (in particular, on BMD-1, 2, 3, 4; GM-352; Ural Typhoon; Object 775, etc.), and obtained by combining various structural elements, which implementation can be useful in the educational process in training personnel. The dependences presented in the article make it possible to obtain static and dynamic elastic characteristics at various polytropic indices and are suitable for the design of suspensions for wheeled and tracked vehicles for various purposes.

Published: January 2022

The perspective energy sources alternative to hydrocarbons, which are currently used in the world, are considered. Energy-saving technologies for the use of hydrocarbon fuel in vehicles are analyzed.
The need to develop the use of electric drives on automobiles is noted. The importance of systematical accumulation and analyzing of the existing experience of operating vehicles with electric drives abroad and in the Russian Federation is considered. Monitoring the technologies developed abroad and the problems arising during the operation of electric vehicles will make it possible to determine the priority ways of their development and to concentrate the efforts of researchers in the direction ensuring the maximum efficiency of their application.
One of the currently attractive and economically viable ways of developing road transport for domestic practice is the use of vehicles with hybrid power plants. It is shown that the production of hybrid vehicles and electric vehicles abroad is successfully developing and is nowadays one of the most dynamic in the world.
Indicators of efficiency of electric power consumption of vehicles with electric drive of various automobile manufacturers are given. A comparative analysis of technologies for the use of electric automobiles to improve the environmental situation in megalopolises is carried out and the problems of increasing the efficiency of automobile power plants are considered.
It is shown that the climatic conditions of the Russian Federation with long periods of low temperatures of atmospheric air strongly affect the energy losses associated with heating the passenger compartment, and to a large extent - on the energy efficiency of the power plant of electric vehicles.
To assess the efficiency of using electric vehicles, it is proposed to use a universal indicator of the efficiency of energy consumption. It is proposed to carry out a comparative assessment of the energy consumption of various vehicles by the energy parameter qEL.
The calculated data show that the use of vehicles with electric drive and, in particular, rechargeable hybrids is more profitable in comparison with the use of vehicles equipped exclusively with internal combustion engines.
Foreign experience of interaction of forensic science institutions with law enforcement agencies and possibility of its use in Ukraine
Authors: Polianskyi Anton , Juodkaitė-Granskienė Gabrielė 
Published: January 2022

The law enforcement sector of our state is a separate mechanism which each element performs a clearly defined functional role that ensures social justice, protection and security of population, territorial integrity of Ukraine. These factors are an incomplete list of features that explain the importance of state activity in law enforcement or human rights. The latter brings together a large array of different actors each of which is entrusted with part of power or socially significant tasks. However, when carrying out law enforcement activities, authorized entities cannot always be able to address certain complex issues that require specific professional knowledge, skills and abilities. Therefore, for their resolving, law enforcement agencies cooperate with specially authorized entities that powers include conducting forensic examinations, in particular, forensic science institutions. In this context, it should be emphasized that ensuring effective cooperation between forensic institutions and law enforcement agencies is virtually impossible without creating appropriate administrative and legal framework for implementation of legal relations in this direction.
It should be noted that in recent years, the legislator scientific circles pays more and more attention to activities of forensic science institutions and law enforcement agencies. However, this does not preclude existence of a number of organizational and legal issues in implementation of these entities of their joint activities.
Thereby in the framework of the presented research we aimed to find out essence, content and features of administrative and legal bases of interaction of forensic science institutions with law enforcement agencies, make maximum use of foreign experience, and develop proposals and recommendations to improve legislation in this area.
