Published: July 2020

Современные подводные аппараты всё чаще оснащаются системами технического зрения (СТЗ). Это позволяет им решать сложные задачи, связанные с распознаванием образов и классификацией. Целью данной работы является описание способа идентификации подводных объектов по оптическому изображению. В отечественной и зарубежной литературе практически отсутствует описание автономных систем, решающих данную задачу, что делает представленную работу актуальной. В статье обоснована целесообразность использования систем технического зрения необитаемого подводного аппарата (НПА) в задачах идентификации подводных объектов. Показана необходимость компьютерного моделирования процесса идентификации объектов на изображении, описан опыт создания базы изображений. В статье приведено описание идентификационных признаков объектов на изображении. Представлен набор признаков, позволяющих идентифицировать внешне похожие объекты с высокой вероятностью. Описан опыт создания программной модели идентификации подводных объектов по оптическому изображению.
Many modern underwater vehicles are equipped with machine vision systems. This allows them to solve complex problems associated with pattern recognition and classification. The purpose of this work is to describe a method for identifying underwater objects from an optical image. In russian and foreign literature, there is practically no description of autonomous systems that solve this problem, which makes the presented work relevant. The article substantiates the feasibility of using the technical vision systems of an autonomous underwater vehicle (AUV) in the identification of underwater objects. The article illustrates necessity of computer modeling of the identifying objects process in an image. The experience of creating an image database is described. The article describes the identification features of objects in the image. A set of features that allows identifying externally similar objects with high probability is presented. The experience of creating a software model for identifying underwater objects from an optical image is described.

Published: July 2020

Учет масштабного эффекта имеет большое значение для задач проектирования судов и их движителей. Сложные формы корпусов судов и современных движителей могут быть представлены в виде комбинации простых базовых элементов, одним из которых является тело вращения. В работе представлен метод учета масштабного эффекта для частного случая тела вращения, обтекаемого в продольном направлении. Метод учета основан на численной оценке обтекания тела вращения с помощью методов идеальной жидкости и расчета пограничного слоя. Расчет пограничного слоя осуществляется путем перехода к плоскому течению. В методе моделируются эффекты ламинарно-турбулентного перехода и отрыва пограничного слоя. Моделирование масштабного эффекта осуществляется путем выбора значений ряда параметров из условия согласования расчета с модельными экспериментальными данными и последующего расчета на большие натурные числа Рейнольдса. Показаны особенности влияния параметров масштабирования на характеристики профиля. Эффективность разработанного метода подтверждена сопоставлением с натурными экспериментальными данными.
Taking into account the scale effect is important for the design of ships and its propulsors. Complex shapes of ship hulls and modern propulsors may be represented as a combination of simple basic elements. The axisymmetric body is one of its. The paper presents a method of accounting for the scale effect for the special case of a axisymmetric body in longitudinal flow. The method of accounting is based on the numerical evaluation of axisymmetric body flow using the methods of ideal fluid and boundary layer calculation. The boundary layer calculation realized by moving to the flat flow. The method simulates the effects of laminar-turbulent transition and separation of the boundary layer. Modeling of the scale effect is carried out by selecting the values of a number of parameters from the condition of coordination of the calculation with the model experimental data and the subsequent calculation for large full-scale Reynolds numbers. The features of the influence of scaling parameters on the profile characteristics are shown. The effectiveness of the developed method is confirmed by comparison with the full-scale experimental data.

Рассматривается возможность интенсификации процесса изготовления разнонаправленных внутренних винтовых пазов трубных корпусных деталей, используемых в судовых энергоустановках и пусковых устройствах для запуска подводных и летательных беспилотных аппаратов, и их элементов, испытывающих многократные нагрузки в период эксплуатации. Для выбора наиболее рационального и эффективного способа изготовления применен функционально-структурный анализ используемого оборудования для изготовления внутренних винтовых пазов трубных корпусных деталей, с помощью которого найдены закономерности процесса. Выявленный способ обработки, оборудования и применяемый инструмент являются наименее затратными и наиболее эффективными для выполнения необходимых технических требований. При проведении анализа зон локальных деформаций выявлен ряд зависимых величин, влияющих на конечное усилие и степень деформации при изготовлении разнонаправленных внутренних винтовых пазов трубных корпусных деталей.
The possibility of intensification of the process of manufacturing of multi-directional internal twist grooves of tubular bodyparts used in ship power plants and launching devices for launch of underwater and aerial unmanned vehicles and their elements experiencing multiple loads during operation is considered. In order to select the most rational and efficient method of manufacturing, functional-structural analysis of used equipment for making internal twist grooves of tubular body parts is used, with the help of which process regularities are found. The identified method of processing, equipment and tool used are the least expensive and most effective to meet the required technical requirements. Analysis of local deformation zones revealed a number of dependent values affecting final force and degree of deformation during manufacture of differently directed internal twist grooves of tubular body parts.

Крутильные колебания упруго-массовых систем относятся к тем опасным динамическим нагрузкам, которые могут приводить к аварийным повреждениям валов, упругих муфт и других элементов энергетических установок с дизельным приводом.
Указанные особенности побудили авторов на первом этапе аналитических и экспериментальных исследований крутильных колебаний универсальной дизель – генераторной установки ДГ-8,83 подготовить обоснованные исходные данные. Для этой цели определены моменты инерции и податливости элементов крутильной системы по известным эмпирическим формулам, по методу конечных элементов и частично экспериментально. Затем на основе анализа и обобщения полученных результатов проведен обоснованный выбор моментов инерции и податливостей в качестве уточненных исходных данных.
На базе выбранных исходных данных авторы намерены приступить к расчету крутильных колебаний с жестким и упругим соединением дизеля с генератором.
Для обеспечения точности аналитических и экспериментальных исследований крутильных колебаний других дизельных установок авторы рекомендуют, прежде всего, подготовки обоснованных исходных данных.
orsional vibrations of elastic-mass systems belong to those dangerous dynamic loads that can lead to emergency damage to shafts, elastic couplings and other elements of power plants with a diesel drive.
These features prompted the authors to prepare reasonable initial data at the first stage of analytical and experimental studies of torsional vibrations of the universal diesel generator set DG-8.83. For this purpose, the moments of inertia and pliability of the elements of the torsion system are determined using known empirical formulas, the finite element method, and partially experimentally. Then, based on the analysis and generalization of the results obtained, a reasonable choice of moments of inertia and pliability was made as updated initial data.
Based on the selected initial data, the authors intend to start calculating torsional vibrations with a rigid and elastic connection of a diesel engine with a generator.
To ensure the accuracy of analytical and experimental studies of torsional vibrations of other diesel installations, the authors recommend, first, the preparation of reasonable initial data.
