 Название: Гравитационная ориентация искусственных спутников Земли: Специальный курс
Автор: Сазонов В.В., Барбашова Т.Ф.
Издательство: Курс
Год: 2023
Страниц: 146
Язык: русский
Формат: pdf
Размер: 11.5 MB
В предлагаемом курсе рассматривается динамика пассивной гравитационной ориентации искусственных спутников Земли. Основное внимание уделено режиму одноосной гравитационной ориентации. В рамках метода Н.Н. Боголюбова - Ю.А. Митропольского построены интегральные поверхности уравнений вращательного движения спутника, описывающие его номинальные невозмущенные движения в этом режиме. В случае, когда уравнения движения допускают обобщенный интеграл энергии или обладают свойствами симметрии, указанные интегральные поверхности состоят из периодических решений. Эти решения детально изучены с помощью аналитических и численных методов. Приведены примеры исследования интегральных поверхностей ориентированного движения в общем непериодическом случае. Исследовано дестабилизирующее влияние сопротивления атмосферы на режим гравитационной ориентации.

Information and communication technology is penetrating all areas of daily life at a rapid pace in private and professional areas. These technologies enable companies to aggregate huge volumes of data. Collected personal data of employees creates the opportunity of a digital representation of the human being itself, that is conformant with the definition of a digital twin. These digital twins of humans include selected characteristics and behaviour of the humans, that are linked to models, information, and data. According to existing trend studies, the digital twin of humans is a technology that will have a significant impact on the economy, society, and people. It is important to consider the regulatory framework for the use of personal data and threats of misuse.

This book investigates in detail cutting-edge technologies of underactuated manipulator control, which is a frontier topic in robotics that possesses great significance in energy conservation as well as fault tolerance for industrial applications. It is also the crucial technology associated with systems in special environments, including underwater or aerospace environments. So far, the topic of underactuated manipulator control has attracted engineers and scientists from various disciplines, such as applied physics, material, automation and robotics. Pursuing a holistic approach, the book establishes a fundamental framework for this topic, while emphasizing the importance of design and optimization in the control of underactuated manipulators. Chapters of the book cover a wide variety of manipulator systems, including vertical underactuated manipulator, planar underactuated manipulator with first-order nonholonomic constraint, planar underactuated manipulator with second-order nonholonomic constraint and flexible underactuated manipulator. The book is intended for undergraduate and graduate students that are interested in underactuated manipulators, researchers that investigate the design and optimization for controllers of underactuated manipulators and engineers working with underactuated systems.

 Название: Creep: Fatigue Models of Composites and Nanocomposites

In recent years, the application of composites and nanocomposites has been increasing steadily in industries such as aerospace, automotive, marine, and civil engineering. It is among the most complex and crucial aspects of the mechanics of a deformable solid, due to several specific phenomena and analytic factors arising from cyclic loading. The problems are primarily associated with the development of fatigue damage, and the need to assess the cyclic and structural instability of composite and nanocomposite materials. The study of structural strength under cyclic loading has gained much attention, especially in aircraft manufacturing, power engineering, aviation, and rocket technology. Cyclic loading significantly reduces creep-fatigue lifespan during the entire frequency range. It is clear that characteristics such as endurance limit, static creep limits and long-term static strength will not suffice in the design criteria for fatigue life. New aspects have emerged in high-temperature strength - cyclical creep and long-term cyclic strength, leading to the creation of new methods and means of determining the resistance of composites and nanocomposites materials and continuum damage development under cyclic loading to the creation of appropriate physical models. Particularly relevant is the intensification of creep by high-frequency cyclic loading in composite materials, which usually occurs at high temperatures.
