The paper studies the properties of brass workpieces for antifriction rings under severe plastic deformation by high-pressure torsion. evolution microstructure and mechanical deformed after six cycles torsion at 500 °C have been studied. All metallographic were performed using modern methods: transmission electron microscopy (TEM) analysis back scatter diffraction patterns (EBSD). resulted in an ultrafine grained structure with a large number large-angle boundaries. strength increased...
предложен вариант кинематического метода теории предельного равновесия; рассматриваются массивные элементы конструкций, материал которых, в общем случае, анизотропный. Принята жесткопластическая модель деформируемого твердого тела. Принято допущение, что конструкций разрушаются путем разделения на части, которые относительно мало деформируются («абсолютно жесткие конечные элементы»,АЖКЭ) и имеют 6 степенней свободы трехмерном пространстве. Процесс разрушения материала идет по бесконечно...
A promising method of obtaining mineral fiber fillers for dry building mixtures is the processing waste that comes from production technogenic fibrous materials (TFM). The novelty work lies in fact that, first time, basalt wastes were studied not only as reinforcing components, but also binder ones involved concrete structure formation. purpose article to study physical and mechanical properties additives optimizing composition raw mixes. To assess possibility using complex TFM ground 5 10...
С увеличением рабочей высоты конструкции ее абсолютная несущая способность растет, а относительная — падает. Подобное поведение является следствием масштабного энергетического эффекта. Данный фактор не учтен в методиках расчета железобетонных плит на продавливание ряда нормативных документов из за отсутствия результатов испытаний толстых плит. Лабораторные испытания подобных конструкций сопряжены с высокими трудовыми и финансовыми затратами. Альтернативой может быть численное моделирование....
The current stage of development building materials science is characterized by the widespread use dispersed reinforcement various compositions and sizes in mortars concretes. In paper, priority scientific technical directions for rational reinforcing fibers, including secondary ones, was established effective resource energy-saving technologies production competitive commercial products construction industry. A study phase formation concrete using technogenic fibrous carried out. Using...
With the constant increase of terrorist attacks on power engineering facilities, including those using UAVs, article notes urgency developing technical solutions to protect these facilities. The describes individual unsuccessful examples protection against UAVs. goal is development constructive and technological energy facilities from UAV attacks. emphasis placed with high reliability, expressed by possibility placing a protective structure in confined nature industrial sites. existing...
The article examines the technology of crushed wood pelletizing from perspective computer simulation modeling. process fine raw material movement inside pelletizer during pressing was studied to identify particle motion characteristics. widespread use specialized software based on Discrete Element Method (DEM) for solving practical industrial tasks related bulk materials revealed. A functional digital model developed in Altair EDEM software, describing while accounting characteristics...
The article considers the approach to determining structure of a high-cross-country chassis and principles calculating its main weight, size energy parameters. relevance problem is determined by lack Russian developments in field creating for road construction machines suitable work difficult terrain. need such ensure implementation operational landscape conditions areas natural man-made disasters. proposed weighing 11 ... 13 tons articulated, three-section. source heat engine (diesel...
Abstract The paper presents data on the resource and wear of gears agricultural tractor transmissions, basis which research problem novelty proposed methodology are formulated, based development application stress state model gear, taking into account surface hardening. calculation scheme for determining power parameters gearing described in detail. In this case, dependences results previous studies field increasing durability reducing transmission elements vehicles various functional...
Abstract Insulation materials play an important role in district heating pipeline networks. Thermal losses pipe insulation systems depend on the thermal conductivity of materials. The is influenced by temperature and moisture content. In this paper effect content rock wool produced different manufacturers was considered. Experimental studies were performed using standard guarded hot plate (GHP) method. Higher always associated with higher for all investigated samples.
The integrated use of agricultural resources, waste processing and the production modern products demanded by market are a steady trend in economy. building materials form light organo-mineral composite with mineral organic fillers is one ways for their utilization. choice especially important conditions high seismic activity proposed construction area. paper presents results studies strength characteristics an made on basis available raw materials-agricultural waste. Straw cotton stalks...
In this article, a method is considered to increase the efficiency of boiler room operation with PTVM-180 boilers by use flue gas in condensing economizer. The evaluation utilization heat exchanger accordance operating mode house was evaluated, and technical economic parameters project were assessed, depending on unplanned changes such key factors as capital costs, time, mode.
This present study developed two predictive and associative Bayesian network models to forecast the tolerable travel time of university students campus. considered built environment experiences during their early life-course as main predictors this study. The were hybridized with Pearson chi-square test select most relevant variables predict time. Two developed. first model was applied only environment, while second all that identified using tests. results showed inclined choose 0–20 min....
The main reason for the emergence of operational characteristics tractor diesel engines is uneven fuel consumption. Fuel equipment one most responsible systems engines. purpose study was to improve efficiency an agricultural engine by using injector sprayer. Modernization needle atomizer carried out directing its guiding surface helical groove at angle α, advancing direction axisymmetric pressure. This includes needle, as it likely be skewed, stuck, and dependent. novelty this design...
Abstract The operation of thermal power plants on the basis steam-gas and gas-turbine installations in summer period year is accompanied by a drop generation electric energy, which leads to decrease profitability station as whole. article discusses one options for improving efficiency gas turbines through use absorption chillers.
