DEVELOPMENT OF A MATHEMATICAL MODEL FOR CALCULATING THE STRENGTH OF THE MAIN FRAME OF THE VL80s ELECTRIC TRUCK BODY FOR RAILWAY ENGINEERING

A mathematical model was developed for the main body frame of the VL80s locomotive for railway engineering, including the justification of the design modes available in operation, the calculation of quasistatic characteristics for static loading modes, for single-thrust and double-thrust modes, for compression and tension modes. A calculation is also made on the effect of distributed inertial loads, then the power factors and stresses in the calculated sections of the main body frame of the VL80s electric locomotive are calculated. Summarizing conclusions are given on the maximum voltages in the design modes of the main frame of the VL80s electric locomotive after upgrading with amplification.

THE DYNAMICS OF SYSTEMS WITH FLEXIBLE OPERATING LINKS AND DRIVES WITH THE IMPULSE AND PULSING OPERATING FLUID PRESSURE

The object of investigation: the system of flexible pipelines, hoses of high pressure, bellows elements. The purpose of the works: the development of the new and existing methods of design of the dynamics of systems with flexible operating links and drives with impulse and pulsing pressure of the operating fluid. The scientific novelty of the investigation is in the generalization, development of methods of modeling of the system dynamics provides with flexible operating links and drives with impulse and pulsing pressure of the operating fluid, and scientific justification of the technical developments. The developed means for modeling of the operational vibration loads for flexible operating links allow to essentially widen the range of the experimental investigations to be performed. The means of small mechanisation for the water pipeline-sewage works with application of the hydraulic drive can be used for the manual mechanization and facilitation of the servicing personnel work. The results of the work can be used in the machine construction, building, medicine and etcAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

Two-axle bogie vibration damping system with additional damping elements

There are no optimal vibration damping designs for safe movement at the present stage of the development of high-speed rail transport. The purpose of improving existing structures is their ability to simultaneously dampen both longitudinal and transverse vibrations. For dynamic research, an analytical method has been developed for calculating the stresses and deformations of the sidewall of the frame of an electric locomotive bogie in motion, taking into account the unevenness of the joints. The result of the work on creating a new design of a two-axle bogie of a railway vehicle, with additional damping elements of the vibration damping system, is the Patent of the Republic of Uzbekistan for the invention No. IAP 06498 [1]. The considered design is universal and suitable for a subway car, motor locomotive, or railcar

Vibration simulation of the spring element of the locomotive swing link

The article presents the simulation of vibrations of a cylindrical elastic rod bent along a helix for the swing link of a locomotive. As a result, methods for calculating the dynamic strength of helical springs for locomotives were developed

Generalized dynamic model of hydrodynamic vibration dampener subject to viscous damping

Use as an elastic body of the working fluid improves the efficiency of the hydraulic damper, reliability, and durability, in this case, the issues of improving the reliability of existing locomotives hydraulic dampers by upgrading separate the components for major repairs with the extension of the useful life are relevant. To increase the efficiency of damping dynamic vibrations and reduce the load on the support units and running gear elements, a modernized design of a hydro friction damper with improved damping properties was developed, for which an application was filed for the Patent of the Republic of Uzbekistan for Invention No. IAP 2021 0002

Hybrid Principles in the Novel “Steamship to Argentina” by Alexei Makushinsky

Цель настоящей статьи — исследовать роман Алексея Макушинского «Пароход в Аргентину» (2014) с позиций теории гибридности. Эта одна из наиболее популярных на сегодняшний день концепций рассматривается в бахтинской интерпретации, где гибридные свойства романа напрямую связаны с его полифонизмом. Ключевым теоретическим основанием работы выступает термин Михаила Бахтина «гибридная конструкция», благодаря чему «Пароход в Аргентину» предстает в виде диалога и спора голосов двух главных героев — архитектора и писателя. Исследуя эти голоса и особенности их взаимодействия в пределах отдельных грамматических высказываний, мы приходим к мысли, что этот вид разноречия связан со стилистическими, смыслообразующими особенностями текста и имеет прямой выход на формальные моменты организации романа. В частности, именно он позволяет наиболее продуктивно рассмотреть особый авторский синтаксис, для обозначения которого мы вводим термин «архитектурное письмо». В статье были использованы следующие методы: сравнительно-сопоставительный (в работе с теоретическими источниками), описательный и метод структурного анализа, которые позволили выявить гибридные конструкции и проследить их связи с идейно-тематическим, смысловым и формальным уровнями текста. Полученные результаты могут быть перспективны для более глубокого изучения творчества Алексея Макушинского, а также в исследованиях идиостиля и эстетической уникальности романов других современных . This paper aims to investigate the novel “Steamship to Argentina” by Aleksei Makushinsky (2014) from the standpoint of hybrid theory. The key theoretical basis of the work is Mikhail Bakhtin’s term “hybrid construction” which is directly related to the polyphonic nature of the novel genre. From this position, the novel appears as a dialogue of voices and languages of the two main characters: the architect and the writer. The authors explore these voices and their interaction within specific grammatical utterances and conclude that they are linked to the stylistic features of the text and its formal properties. To describe Makushinsky’s unconventional syntax, the authors of this article introduce the term “architectural writing”. The obtained results can be used for a deeper study of Aleksey Makushinsky’s creativity, as well as in studies of the idiostyle and aesthetic uniqueness of novels by other contemporary authors
