Тип записи:Публикация, SIGNALS PROCESSING METHOD FOR FIBER-OPTIC SENSORS WITH TILTED FIBER BRAGG GRATING(Mukhametzhan Tynyshbayev ALT University, 2022-10-10); The article presents signals processing method for fiber-optic sensors with tilted Bragg grating. Developed technique is based on the analysis of signals output spectrum to capture Fourier-images in the area. The main idea of the being offered method is in using sensitive tilted fiber Bragg grating fiber-optic sensors. The given sensor is insensitive to any influence in multimode fibers and other parts of the device. Devices, based on such principles, do not need recalibration after switching on and further operation. There is presented the sensor parameters optimization on the basis of numerical modeling. Outcomes of numerical modeling permitted to broaden the domain of internal parameters of sensor’s sustainable operation. - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, ПОСТРОЕНИЕ МОДЕЛИ БРЭГГОВСКОЙ СТРУКТУРЫ С ПЕРЕМЕННЫМИ ТЕХНОЛОГИЧЕСКИМИ ПАРАМЕТРАМИ(Mukhametzhan Tynyshbayev ALT University, 2024-03-28); Построение модели брэгговской структуры с переменными технологическими параметрами остаётся актуальной задачей в современной науке и инжиниринге. Моделирование брэгговских структур с переменными параметрами может помочь в разработке новых материалов с уникальными свойствами, которые могут быть применены в различных областях, от оптики до электроники. В работе представлены результаты численных расчетов, направленных на построение спектров волоконных брэгговских решеток с различными структурными параметрами. Также представлен метод, используемый для разработки математических моделей изучаемых структур. Для этого использовалась система уравнений, сопряженных модов, которая решалась численно с использованием метода матрицы перехода TMM (Transfer Matrix Method). Результаты моделирования брэгговских структур могут быть использованы в различных технологических инновациях, в создании новых типов оптических устройств или в области фотоники. - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, RESEARCH AND ANALYSIS OF THE PROPERTIES OF COMPOSITE MATERIALS. DEFINITION AND CLASSIFICATION OF COMPOSITE MATERIALS(Mukhametzhan Tynyshbayev ALT University, 2023-10-19); Unlike conventional materials, composites have become a suitable form for a range of current applications in industry, hospital and sports. This is combined with their remarkable physical, thermal, galvanic and mechanical properties, as well as, in addition, their low weight and investment cost in the given cases. This review article attempts to provide a general concept of composite materials, definition and classification of composite materials, most commonly polymer matrix composites and metal matrix composites. Polypropylene polyurethane and aluminum alloy were selected as matrices for this extract given their attractive properties and their use in various applications. All kinds of research are devoted to a variety of building materials, material processing and various properties. The determination of mechanical data appears to be a significant iterative process in the development and design of composite materials and their components. With regard to the mechanical properties of composite materials, this article highlights some of the uncertainties and limitations that affect the evaluation of mechanical properties, ranging from material constituents, industrial process, test characteristics and environmental conditions.Цитирования (OpenAlex) 2Цитирования (OpenCitations) 2 - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, TESTING OF AN OPTOELECTRONIC SYSTEM OF DISTRIBUTED FIBER-OPTIC SENSORS FOR MONITORING AND DIAGNOSING THE STATE OF BUILDING STRUCTURES(Mukhametzhan Tynyshbayev ALT University, 2023-04-28); ; Shyngys KenshimovThis article discusses distributed systems of fiber-optic sensors based on Bragg fiber gratings for monitoring and diagnosing the state of building structures, which allow periodic measurements and monitoring of the state of engineering structures, assess trends in their technical condition and thereby facilitate the identification of possible threats. The paper presents the results of experimental tests of an optoelectronic system of distributed fiber-optic sensors based on fiber Bragg gratings. The distribution of deformations has been estimated. The results of the study show that shape changes can be reliably detected using all installation methods and fiber optic sensors before significant cracking occurs in the cement.Цитирования (OpenAlex) 1Цитирования (OpenCitations) 1 - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, INVESTIGATION OF THE EFFECT OF A HYBRID ELECTRIC MOTOR ON THE DYNAMICS AND STABILITY OF THE FUNCTIONING OF UNMANNED AERIAL VEHICLES (UAV)(Mukhametzhan Tynyshbayev ALT University, 2025-11-29); ; The paper discusses the structural features of a hybrid power plant, the ratio of electrical and thermal circuit power, and algorithms for controlling energy and thrust distribution in various flight modes. A mathematical model of UAV motion is proposed, taking into account the thrust, inertial, and energy characteristics of the power plant, on the basis of which an analysis of transient processes, stability along orientation channels, and sensitivity to external disturbances is carried out. A comparison with traditional power plants in terms of maneuverability, stability, energy efficiency, and reliability has been performed. It has been shown that the optimal choice of hybrid drive configuration and control strategies can improve flight stability, reduce oscillation, and improve the quality of response to control actions. The aim of the study is to identify how the choice of hybrid power plant structure, the ratio of electrical and thermal circuit power, and energy flow control algorithms affect the maneuverability, transient modes, and stability of UAVs in various mission profiles. The study proposes a mathematical model of UAV motion dynamics that takes into account the characteristics of the hybrid electric drive, thrust and inertia limitations, as well as simulation of the thrust control and power distribution system operating modes. A comparison with traditional power plants is made in terms of control quality, stability, energy efficiency, and reliability. The results obtained allow determining the optimal ranges of hybrid electric motor parameters and control strategies that ensure increased stability, reduced oscillation in orientation channels, and improved response to control actions. The practical significance of the work lies in the formation of scientifically based recommendations for the design and configuration of hybrid power plants for UAVs intended for long flights, monitoring, and special tasks in difficult operating conditions. The results obtained can be used in the design and tuning of UAV power plants intended for long flights, monitoring, and special tasks in difficult operating conditions. - Некоторые метрики заблокированы вашиминастройками согласия
