Published: October 2020

При эксплуатации автотракторной техники в двигателях периодически могут возникать такие неисправности, как задиры и провороты вкладышей в расточках шатунов и коренных опорах коленчатого вала, требующие капитального ремонта двигателей внутреннего сгорания (ДВС) с заменой, как правило, базовых деталей (блока цилиндров и коленчатого вала). Исследованием установлено, что причиной указанного дефекта являются твёрдые частицы (продукты износа деталей и абразивная пыль), попадающие в зазор «вкладыш – шейка коленчатого вала». Эти частицы нарезают кольцевые риски до бронзы на антифрикционном слое вкладышей, приводя к их нагреву и изменению их первоначальных размеров и в конечном итоге – к провороту вкладышей в постелях шатунов и коренных опорах коленчатого вала на блоке цилиндров. Избежать аварийного состояния двигателей в эксплуатации можно путём применения моторных масел в строгом соответствии с рекомендациями заводов-изготовителей и не допускать увеличения сроков замены масел, указанных в руководствах по эксплуатации.
During the operation of automotive equipment in engines, faults such as scuffings and cranks of bushes in the bores of connecting rods and in the main supports of crankshaft may periodically occur, requiring overhaul of internal combustion engines (ICE) with the replacement of as a rule basic parts (cylinder block and crankshaft). The research found that the reason for this defect is solid particles (parts wear products and abrasive dust) falling into the clearance "thrust bearing – crankshaft pin". These particles cut the annular marks to bronze on the antifriction layer of the thrust bearings leading to their heating and changing their original dimensions and ultimately to the turning of the thrust bearings in the beds of the connecting rods and the main supports of crankshaft on the cylinder block. It is possible to avoid the emergency situation of engines in operation by using engine oils in strict accordance with the recommendations of makers and to prevent an increase in the oil drain intervals specified in the operations manual.

Published: October 2020

Рассмотрены вопросы передачи тепла в хлебопекарной печи от теплогенератора к вторичному холодному теплоносителю – воздуху, особенностью которого является высокая влажность. Передача тепла от теплогенератора к вторичному теплоносителю – сложный процесс. Несмотря на то, что по этой тематике написано много работ и проведено множество исследований, вопрос остаётся до сих пор не полностью изученным. Критериального уравнения, с помощью которого можно было бы определить числа Нуссельта для условий теплоотдачи к влажному теплоносителю, проходящему через шахматный пучок теплообменника, в источниках не представлено. С помощью трёхмерного численного моделирования воспроизведена виртуальная работа теплогенератора, в результате по полученным данным было выведено новое критериальное уравнение и получены коэффициенты теплоотдачи (α), позволяющие в конструктивном методе расчёта теплообменных аппаратов определить площадь теплоотдачи для условий влагосодержания в теплоносителе в интервале d = 0,1…0,6 кг влаги на 1 кг воздуха (в хлебопекарной печи другие условия влагосодержания не используются). Предлагаемое уравнение существенно повышает точность расчёта площади теплоотдачи самого теплогенератора, поскольку учитывает влияние влажности на процесс теплоотдачи.
The issues of heat transfer in the bakery oven from the heat generator to the secondary cold heat-conducting medium, the peculiarity of which is high humidity are considered. Heat transfer from the heat generator to the secondary heat-conducting medium is a complex process. Despite the fact that many works have been written on this topic and many researches have been carried out, the question remains still not completely understood. The sources do not provide a criterion equation by which the Nusselt numbers can be determined for the heat transfer conditions to the humid coolant passing through the staggered bundle of the heat exchanger. Using three-dimensional numerical modeling the virtual operation of the heat generator was reproduced, as a result according to the obtained data a new criterion equation was derived and heat transfer coefficients (α) were obtained allowing in the constructive method of calculating heat exchangers to determine the heat transfer area for moisture content conditions in the heat carrier in the range d = 0.1...0.6 kg of moisture per 1 kg of air (other moisture content conditions are not used in the bakery oven). The proposed equation significantly increases the accuracy of calculating the heat dissipation area of ​ ​ the heat generator itself since it takes into account the influence of humidity on the heat transfer process.

Published: October 2020

В системе SORPAS®метод конечных элементов используется для создания численных моделей, позволяющих моделировать процессы контактной сварки. Моделирование процессов сварки выполняется для определения (испытания) свариваемости новых материалов путём прогнозирования результатов, возникающих в ходе использования конкретных базовых материалов, электродных материалов и параметров процесса сварки. Моделирование является основой для более сложных задач, связанных с оптимизацией и проектированием сварочных процессов. Удобный графический интерфейс содержит автоматические процедуры, позволяющие подготовить входные данные, ускорить построение модели, выполнить численные расчёты (моделирование), а также представить результаты сварочных процессов. После выполнения моделирования программа позволяет отображать кривые параметров динамического процесса в зависимости от времени (например, формы напряжения, тока, мощности и сопротивления, изменения силы и хода электрода, увеличения диаметра сварного шва и т. д.). В процессе сварки система обеспечивает визуализацию распределения температуры, тока, напряжения, твёрдости, а также деформаций и напряжений во всех материалах (элементах данной модели).
The SORPAS®system uses the finite-element method to create numerical models enable to simulate contact welding processes. Simulation of welding processes is carried out to determine (test) the weldability of new materials by predicting the results arising during the use of specific base materials, electrode materials and parameters of the welding process. Simulation is the basis for more complex tasks related to the optimization and design of welding processes. The convenient graphic interface contains automatic procedures that allow you to prepare input data, speed up the model building, perform numerical calculations (modeling) and also present the results of welding processes. After the simulation the program allows you to display dynamic process parameter curves depending on time (for example, the shape of the voltage, current, power and resistance, changes in the force and stroke of the electrode, an increase in the diameter of the weld, etc.). During the welding process the system provides visualization of the distribution of temperature, current, voltage, hardness as well as deformations and stresses in all materials (elements of this model).

Biomechanical Impacts of Forward Head Posture on the Respiratory Function
Authors: Kevin Triangto  , Siti Chandra Widjanantie  , Nury Nusdwinuringtyas  
Published: October 2020

Introduction: Forward head posture (FHP) is a very common problem among the working population. Being one of the most subconscious function in humans, respiratory function utilizes both the diaphragmand external intercostal muscles for quiet breathing. However during labored breathing, many other muscles will be recruited, and mostly these muscles have attachments in the cervical, thoracic ribcage,and even lumbar vertebrae. By the nature of attachments of these muscles on the cervical vertebra and thoracic cage, it is then plausible that FHP would affect the respiratory function.
Methods: Thorough searches were done through international journals for the last ten years regarding the topic of FHP and its impacts to the respiratory biomechanics.
Discussion: Previous studies have reported how prolonged FHP will result in kyphotic posture, reducing the mobility of ribcage, and modifies all respiratory muscular attachments such as sternocleidomastoids, intercostals, and to a certain extent, the diaphragm. All these result in a restrictive lung disorder, signified by reducing spirometry values, such as Forced Vital Capacity, Sniff Nasal Inspiratory Pressure, and Peak Flow Rate.
Conclusion: Forward head posture disturb the respiratory biomechanics.
